Use these base URLs when calling Atum’s hosted services. This page is the source of truth: if a URL in an SDK, example, or older doc points somewhere else, the value here is the correct one.
Mainnet is rate-limited to small payment amounts.Older hosts on *.atumlabs.xyz (staging and legacy environments) and api.atum.network are deprecated.

Notes

  • Payment Gateway is the entry point for most integrations — it handles Direct payments (MPP) and serves x402 corridor defaults.
  • x402 Facilitator is not a separate service: it is /verify, /settle and /supported served by the Payment Gateway under the /x402/v1 prefix. Configure it as a base URL including that prefix, while the gateway’s own base URL stays a bare host — the one thing that’s easy to get wrong now that both point at the same machine.
  • Verifier (Veri-Fill) is normally reached indirectly: its address is returned by the gateway’s /v1/defaults, so you rarely call it by hand.
  • If a URL in an SDK, example, or older doc doesn’t resolve, cross-check this page — it is the canonical list.
  • To confirm the gateway is reachable and see which chains it serves, ask it for its chain defaults. A 200 means reachable and serving; a 404 or 503 is the gateway answering that it cannot serve defaults, which is a gateway-side problem rather than a network one:
