Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

• arxiv_search
• calldata_decode

  Use when you hold raw EVM calldata and need to know what function it calls: returns selector, matching signatures (built-in + openchain/4byte) and ABI-decoded args for each candidate; unknown selectors return signaturesFound:0 instead of an error. Optional {signature} override. Example: 0xa9059cbb… -> transfer(address,uint256) with args. $0.002, no signup; not charged if the call errors.

• domain_lookup

  Domain intelligence: DNS A/AAAA/CNAME/MX/NS/TXT/CAA (DNS-over-HTTPS), SPF + DMARC, RDAP registration/expiry/registrar/status, domain age in days. Useful for phishing/fraud checks and lead qualification.

• eip712_decode

  Decode EIP-712 typed data: domain separator, signing digest, message, and plain-language risk notes (Permit, Permit2, EIP-3009, unlimited values).

• evm_address_lookup

  Look up an EVM address or ENS name on Ethereum + Base: ENS forward/reverse + text records, EOA vs contract (EIP-7702 delegation flag), native balance, tx count, USDC/USDT balances, and ERC-20 name/symbol/decimals/supply if it is a token.

• explain_before_sign
• polymarket_markets
• pubmed_search
• sec_filings
• url_unfurl

  Unfurl a URL: final URL after redirects, HTTP status, title, description, OpenGraph/Twitter image, site name, canonical, favicon, language, published time.

• weather_forecast
• web_markdown

  Use when you need to read a public web page as clean LLM-ready Markdown: Readability main-content extraction (nav/scripts stripped) plus title, byline, excerpt, OpenGraph metadata. {fullPage:true} keeps the whole body; {maxChars} caps output (default 100k). No JavaScript rendering, no PDFs. Example: {url:"https://example.com"} -> {title:"Example Domain", markdown:"# Example Domain …"}. $0.001, no signup; not charged if the fetch fails.

• x402_lint

  Decode and lint an x402 PAYMENT-REQUIRED / PAYMENT-SIGNATURE / PAYMENT-RESPONSE header (base64 or JSON): kind, decoded object, errors/warnings (CAIP-2, checksum, EIP-712 domain, expiry).

• x402_payment_safety_check

  FREE, deterministic pre-payment check for an x402 endpoint. Give {url} (we fetch its unpaid 402) and/or {payment_required} (402 JSON or base64 header), plus optional expected_pay_to, expected_network, max_price_usdc, listed_price_usdc, facilitator_url, client_config {max_per_call_usdc, max_daily_usdc, idempotency_key, allow_any_pay_to}. Returns verdict ok/review/do_not_pay with checks: HTTPS/health, payTo validity & mismatch, unknown asset/network, price sanity vs cap/listing, timeout/replay window, multiple payTo, unknown facilitator, missing spend caps/idempotency.
