  x-guidance: Read the free discovery, input and quote routes first. Paid operations return an x402 challenge carrying the exact amount, asset, network and recipient. Prices can vary with selected tier, inputs or usage; use the actual challenge before approving payment. Support is free and uses a separate wallet ownership signature. Preserve the original request and payment proof for redelivery; never pay again for an unresolved purchase.
  x-trust:
    operator: CONNSKILL GmbH & Co. KG
    jurisdiction: Germany (EU)
    contact: info@connskill.com
    auth: No account or API key. Manual first purchases and private redelivery require a free Sign-In-With-X wallet proof from POST /v1/payments/challenge.
    payment: x402 v2, USDC on Base (eip155:8453), pay-per-call to 0x43B85AE58f0A2505c710Bc715d6f3EB16b1f63dE
    idempotency: A fresh wallet proof bound to the exact original request and payment references can retrieve its retained private result without another payment.
    redelivery: Private redelivery only reads a retained result. A missing result or uncertain purchase remains held for wallet support; it never starts another provider order.
    refund: On-chain settlement is technically final. This does not exclude statutory claims. Invalid input is rejected before settlement; failed delivery must be resolved through the delivery policy and support.
    unclearState: If a purchase times out and we cannot tell whether the provider charged us, you get HTTP 504 with stateUnclear — so you never blindly re-order.
    timeouts: No uptime SLA. Every outbound call has a timeout (provider 20s, DataForSEO 45s, purchase 60s); the gateway hard-caps at 90s and returns 504 rather than hanging.
    rateLimit: Paid service calls have no per-caller rate limit. Wallet challenges have bounded capacity and can return 429. Request size limits apply. We never log your IP; only technical metadata such as User-Agent and Referer.
