FAQ

L402 payment flow questions

What happens during an L402 payment flow?

An agent requests a protected API, receives HTTP 402 Payment Required with an L402 challenge, pays the Lightning invoice, then retries with proof of payment; SatGate returns a paid-call receipt and records the decision for the Evidence Pack.

Why use L402 for agent API access?

L402 can carry payment proof at request time, but SatGate keeps the buyer-safe control layer around it: delegated authority, max budgets, scoped access, and receipts before protected APIs unlock.

Can paid-rail context be combined with access policy?

Yes. SatGate can combine L402 payment with capability tokens, scoped authorization, budget policy, receipt fields, Evidence Pack export, and revocation so payment does not become unrestricted access.
