citation_report
Citation Integrity Report (paid, standard tier)
Verify a bibliography. For every reference: exists, resolves, retracted/corrected/flagged, title/author/year match against the registered record, and a rule-derived fabrication risk — as a signed (Ed25519, RFC 8785 canonical JSON), byte-reproducible JSON report. Input: structured references or BibTeX. No LLM; every claim carries its source and retrieval time. Up to 50 references. Paid: $1.00 USDC per successful call via x402 (eip155:8453). An unpaid call returns the payment requirements (isError). Results carry settled / transaction / network / payer plus the signed report. Use this to check references you already have; to find papers for a question or claim, use evidence_pack_preview / evidence_pack instead.

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {'bibtex': {'type': 'string', 'maxLength': 262144, 'description': 'A BibTeX bibliography (entry key → reference id); at most 262144 UTF-8 bytes — maxLength counts characters and is exact for ASCII.'}, 'options': {'type': 'object', 'properties': {'strict_authors': {'type': 'boolean'}, 'include_unpaywall': {'type': 'boolean'}}, 'additionalProperties': False}, 'references': {'type': 'array', 'items': {'type': 'object', 'properties': {'id': {'type': 'string', 'maxLength': 120}, 'doi': {'type': 'string', 'maxLength': 300}, 'raw': {'type': 'string', 'maxLength': 1000, 'description': 'The citation as free text (used as a bibliographic query when no title is given).'}, 'year': {'type': 'integer'}, 'title': {'type': 'string', 'maxLength': 500}, 'venue': {'type': 'string', 'maxLength': 300}, 'authors': {'type': 'array', 'items': {'type': 'string', 'maxLength': 200}, 'maxItems': 100}}, 'additionalProperties': False}, 'maxItems': 200, 'minItems': 1, 'description': 'Structured references. Exactly one of references / bibtex.'}}, 'additionalProperties': False}
citation_report_large
Citation Integrity Report (paid, large tier)
Verify a bibliography. For every reference: exists, resolves, retracted/corrected/flagged, title/author/year match against the registered record, and a rule-derived fabrication risk — as a signed (Ed25519, RFC 8785 canonical JSON), byte-reproducible JSON report. Input: structured references or BibTeX. No LLM; every claim carries its source and retrieval time. Up to 75 references. Paid: $3.00 USDC per successful call via x402 (eip155:8453). An unpaid call returns the payment requirements (isError). Results carry settled / transaction / network / payer plus the signed report. Use this to check references you already have; to find papers for a question or claim, use evidence_pack_preview / evidence_pack instead. NOTE: $3.00 is above the @x402/core client's default spend cap (maxAmountPerPayment $1.00); raise it (client.setSpendControls) before calling, or the client refuses without sending anything.

citation_report_preview
Citation Integrity Report (free preview)
Free preview. Verify a bibliography. For every reference: exists, resolves, retracted/corrected/flagged, title/author/year match against the registered record, and a rule-derived fabrication risk — as a signed (Ed25519, RFC 8785 canonical JSON), byte-reproducible JSON report. Input: structured references or BibTeX. No LLM; every claim carries its source and retrieval time. Checks only the first 3 references; unsigned; no payment. Use this to check references you already have; to find papers for a question or claim, use evidence_pack_preview / evidence_pack instead.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {'bibtex': {'type': 'string', 'maxLength': 262144, 'description': 'A BibTeX bibliography (entry key → reference id); at most 262144 UTF-8 bytes — maxLength counts characters and is exact for ASCII.'}, 'options': {'type': 'object', 'properties': {'strict_authors': {'type': 'boolean'}, 'include_unpaywall': {'type': 'boolean'}}, 'additionalProperties': False}, 'references': {'type': 'array', 'items': {'type': 'object', 'properties': {'id': {'type': 'string', 'maxLength': 120}, 'doi': {'type': 'string', 'maxLength': 300}, 'raw': {'type': 'string', 'maxLength': 1000, 'description': 'The citation as free text (used as a bibliographic query when no title is given).'}, 'year': {'type': 'integer'}, 'title': {'type': 'string', 'maxLength': 500}, 'venue': {'type': 'string', 'maxLength': 300}, 'authors': {'type': 'array', 'items': {'type': 'string', 'maxLength': 200}, 'maxItems': 100}}, 'additionalProperties': False}, 'maxItems': 200, 'minItems': 1, 'description': 'Structured references. Exactly one of references / bibtex.'}}, 'additionalProperties': False}
citation_report_receipt
Citation Integrity Report (receipt re-fetch, free)
Re-fetch a paid report you already bought, by its request_id, within the cache TTL. Free; no payment; the same signed report (request_id re-attached, unsigned, as on the paid result). Over the hosted endpoint GET /v1/citation-report/receipts/<request_id> serves the same bytes; over a local stdio run only that process can. Not found after the TTL, for previews, or for reports served by another process.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['request_id'], 'properties': {'request_id': {'type': 'string', 'pattern': '^rpt_[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$', 'description': 'The request_id from a paid citation_report / citation_report_large result.'}}, 'additionalProperties': False}
evidence_pack
Evidence pack (paid)
Find 3-10 scholarly candidates for a question or topic. Returns DOI/OpenAlex IDs, authors, year, venue, source URLs, citation context, open-access location, and known retraction/correction warnings. JSON only. Does not claim that a paper proves a statement. Paid: $0.03 USDC per successful call via x402 (eip155:8453). An unpaid call returns the payment requirements (isError). Results carry settled / transaction / network / payer. Use this when the free evidence_pack_preview (at most 3 candidates) is not enough; to check references you already have, use citation_report instead.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['query'], 'properties': {'limit': {'type': 'integer', 'maximum': 10, 'minimum': 3, 'description': 'Papers to return (3-10, default 5).'}, 'query': {'type': 'string', 'maxLength': 500, 'minLength': 8, 'description': 'Question, claim, or research topic.'}, 'fields': {'type': 'array', 'items': {'enum': ['papers', 'relevance', 'impact_context', 'access', 'integrity', 'provenance'], 'type': 'string'}, 'description': 'Optional response minimization.'}, 'to_year': {'type': 'integer', 'maximum': 2100, 'minimum': 1800}, 'from_year': {'type': 'integer', 'maximum': 2100, 'minimum': 1800}, 'open_access_only': {'type': 'boolean'}, 'exclude_known_retracted': {'type': 'boolean', 'description': 'Default keeps retracted records but marks them; true filters them.'}}, 'additionalProperties': False}
evidence_pack_preview
Evidence pack (free preview)
Free triage for a question or topic: returns at most 3 scholarly candidates with DOI/OpenAlex IDs, authors, year, venue, source URLs, citation context, open-access location and known retraction/correction warnings. JSON only; no payment. Does not claim that a paper proves a statement. For up to 10 candidates use evidence_pack; to check references you already have use citation_report_preview.
