Powering payments for modern platforms

Northwind Kestrel Loop Meridian Harbor Fathom

Platform

One API, three primitives

Accept money, send money, and reconcile every movement against a single ledger.

Payments

Card, bank debit and wallet acceptance through one /payments resource. Idempotent by default.

Payouts

Push funds to sellers and users on your schedule. Batched or real-time via /payouts.

Reconciliation

Every movement is a ledger entry. Export to your warehouse or pull it live over GraphQL.

Architecture

Built on a modern stack

The AcmePay platform runs as a set of small services behind a single API gateway. The public API is REST with a GraphQL read layer; everything is documented with OpenAPI at docs.acmepay.duckdns.org.
