Four buyer jobs
Evidence, corridor, comparison, dataset slice. Availability is grade-derived; today only get_price_evidence has eligible supply, as a bounded evaluation. Purchasing additionally requires this deployment's salesEnabled to be true.
Medical-cost facts that arrive with receipts.
For AI agents that need published price information with source provenance, dataset version, a fact hash, and an offline-verifiable service signature.
Integrity you can verify
Canonical fact hash plus Ed25519 signature. Integrity and issuer proof—not a claim of clinical truth.
Built for agents
x402 v2, complete discovery metadata, deterministic responses, and public verification keys.
Honest status: corridor, comparison and dataset-slice jobs are unavailable until real G4 corridor artifacts and G3 supply exist — agents must not attempt payment for them. Published price information only—not medical, legal, or purchase advice.
