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.
