Payments on rails you can reconcile.
Accept payments, send money, and settle every movement against a double-entry ledger you can trust. One familiar REST API — bearer keys, HMAC-signed money-out, idempotent retries, and signed webhooks.
$ curl https://api-sandbox.starpay.example/api/v1/ping \ -H "Authorization: Bearer sk_test_…" { "status": true, "message": "pong", "data": { "pong": true, "livemode": false } }
