Agentic Keychain Quote API

openapi: 3.2.0
info:
  description: 'Agentic Keychain: Autonomous Trading Agents, Signed Results. This API is its skill registry (Agent Skill ROI Registry & Benchmarking); Keychain Trading''s results are read-only static files at https://agentickeychain.com/trading/results.json. This is a commercial registry. It sells some of the skills listed here, through Polar as merchant of record, and its operator earns money when one is bought. The evaluate answer can be "do not buy": it says so when the measured evidence does not cover your task, when the price is not recovered, or when a free alternative is enough. Every purchase ends in a checkout that a human completes. The same operations are MCP tools at /mcp. Fields this API version does not define can appear and have no meaning for a client that does not know them. A kind, delivery or pricing.model value that a client does not know means the capability is not supported by that client; it is never purchasable by inference.'

      description: 'A signed 15-minute price quote with the hosted checkout link. It charges nothing; a purchase requires operator approval in the hosted checkout. Use when: your operator wants the price and the checkout link of a capability that is for sale, for example after an evaluation answered recommend. Not for: deciding whether a capability is worth it (evaluate_capability); a free capability needs no quote. Input: the capability id and, if you evaluated first, the evaluation_id, which links the quote to that evaluation. Output: a quote_id and signed claims bound to the capability version, price, currency, terms and expiry, the checkout link and the unlock request; the price comes from the registry record only.'
