query_claimsSearch claim statements and excerpts. A domain keeps claims whose primary domain is that value or one of its aliases, such as cs.LG for ai-ml. An exact multi-token phrase matches whole tokens. A single ordinary token also matches its singular or plural. When no stored claim hold…
get_evidenceProvenance for one claim. Excerpts are short unless full_text is true. unpublished is true for a private unpublished paper. The stored excerpt, page, and section stay on provenance. An empty provenance doi is filled from a DOI already stored on that row, including the DataCite D…
get_contradictionsList claims stored as contradicting one claim. Returns each opposing claim id, status, evidence strength, and opposition strength. Example: get_contradictions(claim_id="<id from query_claims>").
get_updatesList claims whose last_updated is at or after a timestamp. Use this to read claims that changed after a time you already checked. Returns claim id, status, evidence strength, a shortened excerpt, and source_url, doi, and paper_id when those are known. Example: get_updates(since=…
