issue_api_receipt
Persist a signed commitment to a client-declared HTTP exchange. Public price: 0.002 USDC via x402 when enabled; otherwise requires pilot issuance permission. Preserve the event, idempotency key and original payment authorization on retries. This does not prove independent observation or the truth of the response.
