  headline: >-
    No account, no API key, no signup, no wallet to start. The OpenAPI declares no securitySchemes because there
    is no credential: address search and the sample are always free, the three PIN routes return real data free
    for the first 25 calls per client per day, and past that allowance the only "credential" is an x402 v2
    payment — the route answers HTTP 402 with machine-readable terms and is retried with a signed USDC payment on
    Base or Solana. derive-authentication.py therefore produced nothing from the spec; this profile is built from
    the provider's discovery manifest, x402 resource list, pricing endpoint and the live 402 challenge.

    Verbatim from the root manifest: "none — no signup, no API key, and no wallet needed to start: address search
    is always free and the first 25 calls per client per day to the PIN routes return real data free. x402 (USDC)
    covers anything past that."

  description: >-
    The OpenAPI carries a top-level x-payment {protocol x402, x402Version 2, accepts[]} and per-operation
    x-payment-info {price {mode fixed, amount, currency USD}, protocols[{x402{...}}]}; the agent card carries the
    same terms as the https://x402.org/extensions/payments capability extension. Payment guards documented in the
    changelog: HEAD never settles, size cap, replay pre-check, and the guards cover both the v2 PAYMENT-SIGNATURE
    header and legacy X-PAYMENT (0.4.1).
  observed: >-
    GET https://api.ingest0r.com/v1/parcel/%7Bpin%7D -> HTTP 402, cache-control private no-store, PAYMENT-REQUIRED
    header present, application/json body with x402Version 2 and both accepts[] entries. Nothing was paid.
  mcp: >-
    On the MCP server the 402 is returned in the tool result as _meta["x402/error"] (isError) and payment is
    supplied via _meta["x402/payment"], with the receipt in _meta["x402/payment-response"] and
    agents-x402/priceUSD in tool _meta (changelog 0.4.1).
