}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.

}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 client; choose that client’s privacy settings before sharing private passages.

}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 identifier. An ordinary explicit exact-original bibliography request can also return a separate metadata-only record and references without a model call or creator payment; page status and full-paper evidence remain separate. New runs record remote MCP ingress. A verified ask-scoped API key attributes the run to its wallet; anonymous runs have no wallet owner. Editable client names establish no identity or spending authority.
| Argument | Type | Description |
|---|---|---|
| mode | string | Research depth; default deep. |
| model | string | Optional Keryx model catalog id, for example deepseek-chat. |
| budget | number | Maximum creator-payment budget in USDC; 0 allows free sources without purchases or rewards. Clamped to the caller's tier. |
