Successful response

- unknown

## Other responses

- `400` — Fatal for the request as written: validation failed or required JSON body fields are missing. Fix the request; do not retry it unchanged. Payment is not settled.
- `402` — Payment challenge, not an application error. Read the base64 x402 v2 challenge from PAYMENT-REQUIRED, sign it, and retry the same request with PAYMENT-SIGNATURE. If a post-payment 402 omits PAYMENT-REQUIRED, verification failed: read the new challenge, re-sign, and retry once.
- `404` — The upstream Arkham resource does not exist. Fatal for the same input. Payment is not settled.
- `429` — Per-wallet endpoint rate limit exceeded. Retry with at least 1 second of backoff; keep heavy endpoints at no more than 1 request per second.
- `5XX` — Arkham failed or timed out, including 502 and 504 responses. Retry with backoff. x402 payments and MPP transaction credentials are not settled for failed requests; MPP hash credits are redeemed at admission and are not refunded automatically.
