Provenance and market intelligence for AI agents.A 282,731-node knowledge graph over 273,378 art-market transactions — the Getty Provenance Index, the Knoedler stock books (1872–1971), ERR and wartime-restitution records — served to any MCP-compliant client.
Every answer is cited. Custody gaps are named, never guessed.Hallucination is held under 1%, verified by an externally reproducible evaluation harness rather than self-report. Where the record is silent, Provenio returns an explicit gap — it never asserts clean title.

Provenio's design contract, in one line:no model memorises art history — Provenio lets any model cite it.Every response binds to a verifiable source row; absences come back as namedcoverage_gaps; the evaluation harness that certifies the <1% hallucination rate is re-runnable against the live API.
