Everything you need to settle cross-border payments over the API.
Flux is a set of settlement rails that move value across borders on stablecoins. You get one API, real-time FX, and a single reconciled ledger with on-chain proof.
All requests are made over HTTPS against https://api.flux.example. Responses are JSON.
$ curl https://api.flux.example/v1/payments \ -H "Authorization: Bearer fk_..." \ -d '{"amount":12000,"currency":"USD","to":"BR"}'
The core resource is a Payment. Create one, and Flux handles conversion, routing and settlement.
| Endpoint | Method | Description |
|---|---|---|
/v1/payments | POST | Create a payment |
/v1/payments/:id | GET | Fetch status |
/v1/fx | GET | Live FX quote |
/v1/ledger | GET | Reconciled entries |
Every payment posts a double-entry record to your ledger, with a chain receipt you can verify independently. Export to CSV or query over the API.
Subscribe to payment.settled, payment.failed and fx.updated events. Flux signs every webhook so you can verify the sender.
KYC, AML and sanctions screening run on every rail, in every corridor. We are SOC 2 Type II audited and never custody your float without your sign-off.
