pay_per_call
shallowio.github.Kali123411/k402 · Verify this server
Complete a PER-CALL coin payment. After a paid tool returns a 402 with pay_per_call_offers, pay one offer on-chain from your own wallet, then call this with the 402's `endpoint` and `request_body`, the chosen offer's `scheme` and `payment_id`, and your payment `txid`. The gateway verifies the payment landed and returns the tool's real result. (Alternative to a prepaid session — use this when you'd rather pay each call directly in a specific coin.)
