HTTP 402 · Payment Required
Your agent asks.
We answer 402.
It pays.
It gets the work.
A status code that sat unused in HTTP since 1997 now moves real money. Point your agent at the endpoint, let it sign for $0.03 in USDC, and it gets the result back in the same request. No account, no API key, no invoice.
The payment settles after the work succeeds — never before. A run that fails costs your agent nothing.

Built for a buyer that is not a person
- Priced before it runs
- The 402 response carries the exact amount, the asset and the recipient. Your agent decides with the number in hand, inside whatever spending limit you gave it.
- Paid on delivery
- We verify the signature, run the work, and settle only if it succeeded. Budget exhausted, wrong language, model down — the authorization is cancelled and nothing moves.
- Nothing kept by default
- We store a SHA-256 fingerprint of the input and output, not the text. Ask for

On test money, for now
Payments run on Base Sepolia with test USDC. The protocol, the metering and the settlement are the real thing — the money is not. Mainnet is a deliberate next step, not a missing feature.
