check_citations — PURPOSE: Fact-check EVERY factual claim in a block of text and return a per-claim report — the batch form of verify_claim, for AI-generated drafts or documents before you publish or act on them.
resolve_instrument — PURPOSE: Resolve a security identifier (ticker, ISIN, CUSIP, SEDOL, FIGI) or an instrument name to canonical FIGI records via Bloomberg open symbology (OpenFIGI), WITH provenance and a signed receipt.
extract_claims — PURPOSE: Split text into independently checkable ATOMIC factual claims — the cheap first step of a verification loop (extract -> ground -> attest).
attest_delivery — PURPOSE: Neutral delivery verification for agentic commerce.
