The platform wraps every payload in an envelope: { "data": …, "meta": { endpoint, version, generated_at, freshness, sources, request_id, docs, data_mode } }.
Unpaid requests receive 402 with payment requirements (accepts). Pay dynamic ($0.01 for hours ≤ 48, $0.03 beyond) in USDC on Base per call via an X-PAYMENT header — see docs.x402.org. With PAYMENT_MODE=disabled (local dev) the endpoint is open.
| Status | Code | Meaning |

| 400 | INVALID_PARAMS | Input failed validation; message lists the offending fields. |
| 404 | NOT_FOUND | No matching resource; suggestion may point to a sibling endpoint. |
| 410 | RESOLVED | Market/event settled; body includes a resolution summary. |
| 503 | STALE_DATA | Upstream feed down; stale data is never silently served beyond 2× cache TTL. |
| 500 | INTERNAL | Our bug. The request_id helps us find it. |
