How it works
Every payment follows the same three-step cycle. This pattern is the same whether you're charging for an API call, a bot interaction, or a long-running job.
- 1 Quote — Your service creates a payment request specifying amount, terms, and expiry. Returns a signed quote token.
- 2 Settle — The buyer submits the quote token to APISettle. Payment settles on-chain in under a second.
- 3 Redeem — Your service redeems the settlement token to confirm payment. One-time use, atomic, replay-proof.
