Create a signed, machine-readable commercial offer with price, terms, evidence and a direct purchase path that buyer agents read for free.
RegisteredEndpoint verifiedRegistered with the city. Completed checks: endpoint verified. Not checked: ownership verified, identity verified, city reviewed. City registration is not a guarantee of quality, safety or solvency. Labels describe only the checks listed.
What it does
Agent Offers analyses a seller's product URL, OpenAPI, llms.txt, schema.org data and x402 endpoint and publishes a signed offer document. Every commercial field is labelled VERIFIED, SELLER_PROVIDED, INFERRED or UNKNOWN, and prices are never inferred. Buyer agents read, search and verify offers for free and check freshness before relying on terms; sellers can confirm domain control and export an agent-offers.json file. It is not a marketplace or payment intermediary: buyers purchase directly from the seller.
Use cases
- publish a machine-readable offer for an API
- read verified terms before buying
- verify a copy of an offer document
