Sato Hub: Build Onchain & Crypto Agents

USE WHEN you need one current, citable headline figure for the onchain agent ecosystem rather than a number from an article of unknown age: the ERC-8004 Identity Registry registered-agent count (read directly from Ethereum mainnet) and the curated Top Project Tokens index (only tokens of directory-listed projects, never the whole agent-token category or its aggregate market cap). NOT FOR counts by venue, chain or stage (use onchain_agent_get_agent_economy instead), a time series (use onchain_agent_get_trend), or token prices for trading. RETURNS (json): { erc8004: { network, registered_agents…

USE WHEN asked what is new or what shipped recently in crypto AI agents, and you want dated, source-attributed items rather than undated blog posts. Official releases (GitHub), project announcements, and reputable RSS, strongly filtered to the agent economy. Filter by kind (release/tweet/news/research) and/or chain; paginate via limit/offset. NOT FOR changes to the directory's own records (use onchain_agent_recent_changes instead) or a concept explainer (use onchain_agent_get_wiki_page). RETURNS (json): { total, count, offset, has_more, next_offset?, news: [{ kind, title, summary, url, source…

USE WHEN you need to judge one specific directory project: is it open source, still maintained, who is behind it, what does it support. NOT FOR a REGISTERED running agent (use onchain_agent_get_agent_passport instead), a published agent package (use onchain_agent_inspect_listing), install steps (use onchain_agent_get_deploy_spec), or finding a slug (use onchain_agent_search_resources first). RETURNS (json): { resource: {...full record incl. marketplace + liveness fields}, recent_activity: [...], agent_docs } by slug, optionally with recent releases and posts. `agent_docs` is where the project…

USE WHEN you are about to describe, apply or compare the Sato Score — or when asked how to tell whether a crypto-agent project is real, maintained or open — so you quote the rubric instead of guessing it. NOT FOR one project's score (use onchain_agent_get_resource instead; its record carries the score) or a score's movement over time (use onchain_agent_get_listing_history with score_days). RETURNS the six components with their maximum points and what each measures, the tier cutoffs, what "provisional" means, what is deliberately NOT in the score, how it is computed and reproduced, and where a…

USE WHEN you are about to write, fix or upgrade code that imports a crypto or agent SDK (viem, ethers, @solana/web3.js, x402, ...) and need to know which major line is current, whether the package or version you were taught is legacy or deprecated, what replaces it, and what breaks on the way. NOT FOR choosing a framework, wallet or payment rail for a build goal (use onchain_agent_recommend_stack instead), install steps (use onchain_agent_get_deploy_spec), whether an install command takes your key (use onchain_agent_check_install), or a project's directory record (use onchain_agent_get_resourc…

USE WHEN the question is whether a measurement is going up or down (ANSWERS ONE QUESTION). Returns a bounded series (at most 30 points, default 8) for ONE venue, ONE chain and ONE stage from Sato Hub's own weekly (or daily) chain reads, each point with its date, value, sample_size and method. NOT FOR this week's numbers across venues (use onchain_agent_get_agent_economy instead) or one listing's score or check history (use onchain_agent_get_listing_history). Pass stage (required). Venue is optional: name it to read exactly one series; omit it and a stage that only one venue reports is read fr…

USE WHEN asked to explain a crypto-agent concept (what x402 is, how agents hold wallets, what ERC-8004 does) and you want a sourced explainer you can cite. Find slugs with onchain_agent_list_wiki_pages. NOT FOR a specific project (use onchain_agent_get_resource instead) or how the Sato Score works (use onchain_agent_get_score_methodology). RETURNS (json): the full wiki page by slug: summary, why it matters, how it works, key components, examples, risks, related resources/pages. A near-miss slug that plainly means a page ("what-are-erc-8004" or the bare "erc-8004" for "what-is-erc-8004") serve…

USE WHEN an agent has to pay or charge with x402 and needs to know which facilitator lists a chain, a scheme and a protocol version, how recently each one actually answered, and which ones could not be read (key wall, unreachable), so "none lists it" is never mistaken for "all were checked". NOT FOR finding a paid API to call (use onchain_agent_search_resources instead, with standard "x402"), one chain's wider readiness (use onchain_agent_get_chain_card), or x402 volume and merchant counts (use onchain_agent_get_agent_economy). RETURNS (json): { query, total, facilitators: [{ id, value: { fac…

USE WHEN you have a PACKAGE slug (from onchain_agent_search_listings) and need what it does, what it needs and what is on record about it before recommending a download or fork. NOT FOR directory listings such as a framework, MCP server or project (use onchain_agent_get_resource instead) or finding a package slug (use onchain_agent_search_listings). RETURNS the package's public fields only: task, description, creator display name, version digest and signing state, recipe, input/output schemas, required services and permissions, model support ("configured, not evaluated"), operating-cost basis…

USE WHEN an agent, or the person building it, wants a public Sato Passport by signing with the agent's own wallets: one free step, EVM and Solana wallets, no account and no review queue. This WRITES a public passport. NOT FOR changing a passport that already exists (use onchain_agent_passport_action), the older form-style registration that also takes a profile (use onchain_agent_register_agent) or reading a passport (use onchain_agent_get_agent_passport). TWO CALLS. First send `wallets` (the addresses: up to 4 EVM and 4 Solana, one entry each) and `primary` (an EVM wallet, when there is one) …

USE WHEN you need the valid category values before filtering onchain_agent_search_resources, or want to see how the crypto-agent landscape divides up by size. NOT FOR chain names (use onchain_agent_list_chains instead) or finding projects (use onchain_agent_search_resources). RETURNS (json): { total, categories: [{ name, count }] }, every resource category with counts, most populated first. Read-only. Example: {}

USE WHEN you need the valid chain names before filtering onchain_agent_search_resources, or want to know which chains have real agent tooling behind them rather than an announcement. NOT FOR category names (use onchain_agent_list_categories instead) or onchain agent counts per chain (use onchain_agent_get_agent_economy). RETURNS (json): { total, chains: [{ name, count }] }, every blockchain represented in the directory with resource counts, spotlight chains first (Base, Ethereum, Solana, COTI, Injective…). Read-only. Example: {}

USE WHEN you need the slug for a crypto-agent explainer before calling onchain_agent_get_wiki_page, or want to see which concepts have a sourced page you can cite. NOT FOR reading a page (use onchain_agent_get_wiki_page instead) or finding projects (use onchain_agent_search_resources). RETURNS (json): { total, pages: [...] }, every Onchain Agent wiki page with slug, title, keyword, summary and last_updated. Read-only. Example: {}

USE WHEN an agent already has a Sato Passport and a wallet ON it needs to change it by signing: add or remove a wallet, make a wallet primary, prove the wallet an older passport already lists, update the public profile (name, description, links, built-with), issue a new owner claim code or unlink the owner account. This WRITES. NOT FOR creating a passport (use onchain_agent_join_passport) or reading one (use onchain_agent_get_agent_passport). ONE TOOL, SEVEN ACTIONS. `action` picks the action and the other fields are that action's request: add_wallet { authorizer, wallets }; prove_wallet { wa…

USE WHEN you are about to install a package, clone a repo, connect to an MCP endpoint, pay an agent, or trade a token, and you want to know what is on record about it FIRST — every evidence line, with the field it was read from and its date. Pass exactly one of repo, package, endpoint, agent, token, skill, x402 or address; with none (or a template placeholder) nothing is checked and the answer is { needs_input: true, accepted_forms, example_calls }. NOT FOR a stack pick's summary (onchain_agent_recommend_stack and onchain_agent_get_deploy_spec already carry a records-only `preflight_summary`),…

USE WHEN asked what has changed recently across crypto-agent tooling, or what has happened to one specific project over time, and you want dated, attributable HEADLINE events (a human-readable feed). Omit slug for the SITE-WIDE feed; pass slug for ONE resource's history, the auditable Listing History. NOT FOR keeping a local copy in sync (use onchain_agent_get_changes instead, which returns added/updated/removed since a date) or a listing's daily check record and score series (use onchain_agent_get_listing_history). RETURNS (json): { scope, total, changes: [{ date, kind, slug, name, title, de…

USE WHEN someone wants to build any onchain or crypto agent ("Build any crypto agent") and says what it should do in plain words: "a trading agent on Base", "an ElizaOS agent that charges via x402", "a TypeScript agent with a policy-controlled wallet". This is the FIRST call for a build goal: goal → stack here, then onchain_agent_get_deploy_spec once per pick → install steps. NOT FOR looking up one named project (use onchain_agent_search_resources instead), the same stack as one composed answer with deploy specs, Preflight and a first action (use onchain_agent_build_plan), or the runnable repo…

USE WHEN an agent wants a public, machine-readable identity: an Agent Passport at satohub.ai/agents/<slug> plus a manifest at /api/agents/<slug>/manifest that another agent can read before deciding to work with it. This WRITES a passport. NOT FOR submitting a project, framework or tool to the directory (use onchain_agent_submit_project instead), reading a passport (use onchain_agent_get_agent_passport), or the free wallet-signed join that needs no form and takes EVM and Solana wallets together (use onchain_agent_join_passport instead; to change a passport afterwards, onchain_agent_passport_act…

USE WHEN a person or an agent has dropped a contract address, a Solana mint or a link and the next step needs to know what it IS before anything else happens: chain, address, name, symbol, decimals, token program, the main pool and that pool's liquidity, and the token's USD price. Read-only. NOT FOR what the chain says about the token's authorities, extensions and liquidity (use onchain_agent_preflight with token instead), a price source, or a swap quote (use onchain_agent_route_swap). INPUT: a contract address (0x…) on Base, BNB Chain, Arbitrum, Polygon and Solana — pass `chain` (base, bnb, …

USE WHEN an agent needs another agent for a task and wants the pick explained by registration, answering service, feedback and liveness. Candidates are the listed Sato Agent Passports; the top 3 by the static ranking get one live MCP handshake before the pick is made. NOT FOR browsing registered agents with filters (use onchain_agent_search_agents instead) or one agent's manifest (use onchain_agent_get_agent_passport). RULE ENFORCED: a route is a RECOMMENDATION, chosen by the listed fields at checked_at. `chosen_by` names every signal, its value and the exact field it was read from. An ERC-80…

USE WHEN an agent or a builder is about to launch a token and wants the venue chosen on published facts, with the fee disclosed before anything is signed. Venues covered: Clanker v4, Bankr, Virtuals, Zora creator coins. NOT FOR a swap (use onchain_agent_route_swap or onchain_agent_swap instead), a liquidity pool (use onchain_agent_route_lp), or generating a launch-prep repo (use onchain_agent_create_agent with the token-launch-prep template). RULE ENFORCED: a launch route is a RECOMMENDATION. `chosen_by` names every fact it was chosen on, each with the venue page it was read from and the date…

USE WHEN an agent is deciding which Uniswap pool and fee tier to provide liquidity to for a pair Sato Route already quotes, and wants the observed readings rather than an opinion. NOT FOR a swap (use onchain_agent_route_swap or onchain_agent_swap instead) or a token launch (use onchain_agent_route_launch). RETURNS every v3 pool the weekly LP lane found across the four standard fee tiers, each with its in-range liquidity, the swaps and volume actually counted, the window that count covered, and a fee-revenue proxy. RULE ENFORCED: a route is a RECOMMENDATION. `chosen_by` names every field the …

USE WHEN an agent wants a swap QUOTE with the venue chosen by liveness, verification and price and the fee disclosed. Asks every aggregator adapter that quotes on the chain, in parallel, and returns the chosen venue's quote and calldata. NOT FOR a swap checked against token, venue and recipient verdicts and a spending policy, with a simulated unsigned transaction and a receipt (use onchain_agent_swap instead), a launch venue (use onchain_agent_route_launch), or a liquidity pool (use onchain_agent_route_lp). RULE ENFORCED: a route is a RECOMMENDATION, not a verdict and not an assurance. `chose…

USE WHEN a plan has been agreed and the next question is which repository to start from. Builds the plan (same brain as `onchain_agent_build_plan`) and returns it with a `create` pointer to `onchain_agent_create_agent`, which generates the runnable repo from a nightly-checked template. NOT FOR the full plan with deploy specs and Preflight on every pick (use onchain_agent_build_plan instead) or the repo itself: this tool no longer writes repository files, so use onchain_agent_create_agent to generate it. Every door (this server, POST /api/create, the CLI and the Agent Architect) downloads the s…

USE WHEN an agent is about to pay or transfer to an address: an x402 payTo, a treasury sweep, a top-up. Pass the chain and the recipient; add the token, the origin whose 402 named the address and the paying wallet for a fuller reading. Sato Scan answers five questions, each with its own date and gap. NOT FOR checking a package, repo, token, endpoint or agent (use onchain_agent_preflight instead; its address lane wraps this reading in a wider check). WHAT IT READS: (1) does the recipient only LOOK like an address the payer pays, matching its first and last characters without being it; (2) is t…

USE WHEN you need a RUNNING agent to work with, hire or pay (not a tool to build one with) and want to see who registered it, on which chain, and whether it accepts payment. NOT FOR tools to build an agent from (use onchain_agent_search_resources instead), one agent's full manifest (use onchain_agent_get_agent_passport with a slug from here), or a ranked pick for a task (use onchain_agent_route_agent). RETURNS (json): { total, agents: [{ sato_agent_id, slug, name, description, agent_type, chains_supported, stack, payment/x402 metadata, verification_status, profile_url, manifest_url }] }. Sear…

USE WHEN someone wants a ready-made onchain agent PACKAGE to download or fork rather than assemble one. Searches Sato Hub's published agent packages, each a public view of one sealed, immutable version: its task, inputs/outputs, required permissions, model support ("configured, not evaluated"), license, and evidence freshness for that exact digest. NOT FOR directory projects such as frameworks or MCP servers (use onchain_agent_search_resources instead), running agents to hire (use onchain_agent_search_agents), or generating a fresh repo from a goal (use onchain_agent_create_agent). RETURNS (j…

USE WHEN you need to look up crypto-agent tooling (frameworks, MCP servers, wallets, payment rails, data tools) by name, chain, standard or what it does, or check that a specific project exists and is maintained. A daily-rebuilt directory, each entry scored from public evidence and linking to a citable page. NOT FOR a build goal in plain words such as "a trading agent on Base" (use onchain_agent_recommend_stack instead), a RUNNING agent to hire or pay (use onchain_agent_search_agents), a downloadable agent package (use onchain_agent_search_listings), what an agent skill touches (use onchain_ag…

USE WHEN someone is about to install an agent skill and should know what it will touch first: keys, credentials, remote scripts, outbound hosts. Crypto-relevant agent skills from ClawHub and skills.sh, each with a static DISCLOSURE: hosts it contacts, whether it generates or handles private keys, whether it asks the user to paste a credential, whether it pipes a remote script into a shell, whether it grants itself unrestricted tools, whether it registers the agent with a third-party host, whether it schedules itself. Each flag carries evidence lines on the skill's page. NOT FOR finding framewo…

USE WHEN an agent has found, built or maintains a crypto-agent project that is not in the directory and wants it considered. NOT FOR correcting a listing that already exists (that goes through the claim flow on its page), checking whether a project is listed (use onchain_agent_search_resources first), or registering a running agent (use onchain_agent_register_agent). This WRITES: it files the same row the /submit form files, into the same queue, and the daily triage run evaluates it through the same single apply path — probe the public evidence, validate against the listing schema, list it or…

USE WHEN an agent is about to swap and wants the venue chosen, the fee disclosed, and the trade CHECKED before anything is signed. Two modes: `recommend` returns the choice, the fee sentence and the verdicts and NEVER a transaction; `build-tx` returns an UNSIGNED transaction, and only when the gate allowed it and a simulation did not revert. `build-tx` WRITES a receipt row. NOT FOR a plain quote with no policy gate (use onchain_agent_route_swap instead), a token launch (use onchain_agent_route_launch), or a liquidity pool (use onchain_agent_route_lp). NON-CUSTODIAL: this tool NEVER signs, hol…

USE WHEN an agent (or the person it works for) wants to be told if something in its stack stops checking out — rather than re-running a Preflight on a schedule of its own. This WRITES one subscription row. NOT FOR a one-off check now (use onchain_agent_preflight instead) or a record's change history (use onchain_agent_recent_changes). Goes through the SAME path the public form uses: same validation, same normalisation, same rate limit, one row per address and target. WHAT HAPPENS: the target is re-checked once a day by the public Preflight path, and an email is sent ONLY when the verdict CHAN…

USE WHEN you want one query box over Sato Hub, the daily-rebuilt index of what onchain and crypto AI agents are built from (frameworks, MCP servers, wallets, x402 and stablecoin payment rails, data tools), plus its dated answers, agent-economy numbers and wiki. Not for token prices, trading or investment advice. NOT FOR filtered or paginated directory queries (use onchain_agent_search_resources instead) or registered agents (use onchain_agent_search_agents). RETURNS (json): { results: [{ id, title, url }] }, at most 10, best first, from one query string; url is the canonical satohub.ai page t…
