  • deliverable_acceptance_readRead your delivered-version acceptanceread-only

    Owner-only ordinary prepaid A2A deliverable state. Requires explicit deliverable:read. Historical remedy:none and missing response window remain visible. Native/enrolled, Monthly, private v2 and browser-only originals are unavailable. Not source-decision agreement or semantic verification.

  • deliverable_acceptance_submitRecord your deliverable choice or request

    Record Accept, Request revision or Reject for the original customer's exact retained delivery. Requires explicit deliverable:write, expected current revision/digests and an idempotency key. Reason is private; publishState explicitly shares state/timestamp only. Request storage does not execute a revision/refund, recharge, change reservations or claw back rewards. Your MCP client may retain private messages.

  • draft_checkCheck a draft's cited claims against supplied source textread-only

    Split a private passage into sentences, bind citation markers ([3], cite{key}, [@key], Author (Year)) to a BibTeX, RIS or DOI/link reference list, and compare each cited sentence with source text you supply. Each verdict (supported, partly-supported, not-found, source-unavailable) carries a verbatim excerpt of that text or states that no supporting passage was found; a source without supplied text is always source-unavailable. Deterministic wording comparison, not semantic review. No fetching, model, database, history, payment or reward I/O. Inputs and results can be retained by your MCP clien…

  • evidence_draftAssemble a private retained-evidence draftread-only

    Assemble user-selected claim spans and related-work quote themes from saved Include paper records and caller-supplied retained Keryx report rows. A theme may carry author-written statements (contribution, agreement, disagreement, gap); a statement naming a paper is exported only with a citation and a selected retained excerpt from each named paper, otherwise it is withheld. Exported citations and BibTeX/RIS entries are checked to correspond one to one. Exact version/excerpt matching does not authenticate imported reports or verify semantic support. No fetching, model, database, history, paymen…

  • evidence_procurementPlan and inspect private evidence procurementread-only

    Assess missing evidence requirements, supplied provider offers, selections, deliveries and caller reviews with the shared private evidence procurement contract. Amounts are exact integer micro-USDC. Signature and content-binding checks do not establish delivery quality, buyer authority, payment or settlement. No fetching, model, provider, database, history, purchase, escrow or reward I/O. Caller selections and reviews are assertions, not financial authorization. Inputs and results may be retained by your MCP client; choose its privacy settings before sharing private material.

  • history_exportExport your owned history metadataread-only

    Same owner-private v2 contract as /api/me/asks. Explicit history:read required. Current store, bounded filters/keysets; missing membership/claims stay explicit. Export has explicit truncation/continuation. No research, signer, payment, public-owner selector or mutation authority.

  • history_owned_readRead your owned historyread-only

    Same owner-private v2 contract as /api/me/asks. Explicit history:read required. Current store, bounded filters/keysets; missing membership/claims stay explicit. Export has explicit truncation/continuation. No research, signer, payment, public-owner selector or mutation authority.

  • history_private_jobs_detailRead one of your completed private resultsread-only

    Private data for this authenticated caller only. Exact-payer completed private jobs in the current store; explicit history:read required. Bounded scan/continuation, unknown provenance and NULL own spend/creator settlement remain explicit. No wallet selector, public report/share link, model prompt, research, source fetch, signer, purchase or mutation authority.

  • history_private_jobs_exportExport your private job metadataread-only

    Private data for this authenticated caller only. Exact-payer completed private jobs in the current store; explicit history:read required. Bounded scan/continuation, unknown provenance and NULL own spend/creator settlement remain explicit. No wallet selector, public report/share link, model prompt, research, source fetch, signer, purchase or mutation authority. Manual finite JSON metadata export only; complete/truncated and continuation are returned. Result bodies are excluded.

  • history_private_jobs_listList your completed private jobsread-only

    Private data for this authenticated caller only. Exact-payer completed private jobs in the current store; explicit history:read required. Bounded scan/continuation, unknown provenance and NULL own spend/creator settlement remain explicit. No wallet selector, public report/share link, model prompt, research, source fetch, signer, purchase or mutation authority.

  • history_readRead your attributed dispatch historyread-only

    Read bounded pages of the verified API-key wallet's ordinary current-store runs. Requires explicit history:read. Literal case-sensitive question search; storeNetwork describes the deployment, not per-run settlement. Recorded spend/allocation is not a payment receipt. No wallet selector, linked accounts, archive, private jobs, research or payment.

  • keryx_operator_statusKeryx business Operator statusread-only

    Observe public prepaid research operations, queue, recorded ordinary/recovered/unknown completion latency cohorts and hold/review rationale. Timing is order createdAt to updatedAt (acceptance to recorded completion/update); later reconciliation can extend it. It is not first-answer or settlement time. Missing capability stays null. No spending or execution authority; exact books and customer jobs stay private.

  • keryx_public_job_ledgerPublic job transfer ledgerread-only

    Inspect a partial selected-network public web-dispatch transfer ledger and balanced exact micro-USDC vouchers. Browser funding and Keryx sponsorship are separate. Pending/ambiguous/batched-attribution legs do not enter settled totals. No customer questions/identities, private invoices, complete business books, margin, cash balance, signing or execution authority. days1–31, default7. Export via /api/operator/ledger; a checksum is not authenticity or independent settlement proof.

  • keryx_purchase_outcomesRecorded dispatch purchase outcomesread-only

    Read a public dispatch's retained exact-version BUY/citation/payment observations. Returns bounded sample counts, citation hit rate, calibration bands and integer micro-USDC uncited access cost. Recorded settlement is not revalidated on chain. Historical participant cohort is unknown; causal regret, missed value and cost per supported claim are unmeasured. No research, paid read, current-source backfill, private reviews, signing or learning. Use an existing dispatch ID, never a URL.

  • keryx_source_learningRecorded source learning sampleread-only

    Read the same bounded observational source/topic record as the public creator page and API. Only write-time independently classified/funded outside observations qualify; owners, unknown and private history are excluded. Source-declared public topics, counts, recorded citation contribution, exact rational average access price, descriptive uncertainty and abrupt-shift flag. No questions, wallets or receipt identifiers. Recorded settlement is not independently revalidated. Live learned selection and exploration are withheld, with zero live exploration allowance. No research, source read, payment,…

  • keryx_statusKeryx remote MCP statusread-only

    Describe this MCP surface, its payment behavior, and the active caller tier.

  • operator_obligations_readRead delegated Operator obligationsread-only

    Read a private conservative obligation projection for the exact server-delegated reader with explicit operator:read API-key scope. Disabled without protected reader/role configuration. Partial native history remains unknown with zero safe/advisory surplus. No cash probe, signer, custody, spending, release, refund or scheduler authority. No caller owner/role selectors.

  • paper_lookupLook up paper bibliographyread-only

    Find paper titles, recorded contributors, DOI and exact repository versions without research or payment. Default: retained catalog metadata with observation times. Set searchRepositories=true only to explicitly send the query to arXiv/Crossref (at most two requests, no paper-body reading). Missing DOI, peer review and withdrawal/replacement status remain unknown. Returns a field-scoped bibliography card with provenance, a short reference and reusable BibTeX/RIS text. Use this for exact title/ordered author/year/journal/DOI/version questions before requesting paid research; original paper text …

  • profile_identities_readRead your verified profile identitiesread-only

    Read only the verified key owner's saved ORCID/GitHub identities. Requires explicit profile:read scope. No wallet selector, provider OAuth, linking, unlinking, research or payment. Link identities interactively in your private profile browser page.

  • researchResearch with Keryx

    Research a question under a USDC creator-payment budget. Keryx selects sources, pays access tolls and weighted citation rewards on the configured Arc network, then returns qualified source excerpts and a receipt. Complete synthesis and per-assertion entailment remain unverified. This remote surface uses Keryx's treasury; anonymous research is sponsored, not caller-funded usage. Public research may send your question to our search provider. The source USDC budget is separate from model and search operating costs. For retained or repository bibliography use free paper_lookup with an exact identi…

  • research_feedback_readRead feedback for your original answerread-only

    Original-caller private opinion on the exact delivered ordinary research answer. Requires its private bearer capability; a public report ID or link grants no authority. First choice is retained, exact retries are idempotent. Silence is no response. No research, source fetching, revision execution, refunds, signing or payments.

  • research_feedback_submitRecord usefulness of your original answer

    Original-caller private opinion on the exact delivered ordinary research answer. Requires its private bearer capability; a public report ID or link grants no authority. First choice is retained, exact retries are idempotent. Silence is no response. No research, source fetching, revision execution, refunds, signing or payments.

  • research_monthlyResearch Monthly pilotread-only

    Read the four-request, 30-day Research Monthly quote and handoff. The current quote identifies its payment network. Never buys or redeems a plan.
