model: pay-per-task in RLUSD on the XRP Ledger via x402; no subscription, no account, no free tier for the task itself
summary: >-
  The oracle publishes exactly one price and publishes it machine-readably three times over: in the agent
  card's required payment extension, in the x402 resource-server manifest at /.well-known/x402, and in the
  live 402 PaymentRequirements the endpoint returns to any unpaid call. 0.01 RLUSD per task, exact scheme,
  settled on XRP Ledger mainnet (xrpl:0) through the t54 facilitator, with a 600-second window per challenge.
  The card's inputSchema says deep=true is "more expensive/slower", but no second price is published anywhere,
  so no deep-tier price is recorded. The free surface is the card, the manifest, the OpenAPI, the Swagger UI
  and /healthz.

    no API and is not this surface: Free ($0, 3 sources, weekly digest), Solo ($19/mo, 15 sources, daily digest
    + alerts), Pro ($39/mo, 40 sources, 3 projects, shareable web digest, Slack). Marked "Indicative. Waitlist
