## Notes

- Start with a free *-quote or *-services endpoint to discover valid inputs and
  the exact price before paying anything.
- Prices are live; https://agent.connskill.com/.well-known/x402 is the authoritative source.
  Human-readable price table with the refund/idempotency/timeout policy: https://agent.connskill.com/pricing
- Idempotent: repeat the SAME request with the SAME payment header and you get
  the stored result back — a settled payment is never charged twice.
- Missing something? POST /v1/wishlist {"want":"..."} — free request board, we
  build what agents actually ask for.
