Public Infrastructure

The IOTA Foundation provides the following loadbalanced public testnet endpoint:

  • api.lb-0.testnet.chrysalis2.com

We recommend using the load balancer for most scenarios.

Single node endpoints that expose native MQTT, in case you need them, are:

  • api.hornet-0.testnet.chrysalis2.com
  • api.hornet-1.testnet.chrysalis2.com
  • api.hornet-2.testnet.chrysalis2.com
  • api.hornet-3.testnet.chrysalis2.com

These endpoints have MQTT (via WebSockets and raw TCP) exposed and offer the HTTP REST API (according to this specification) over TLS.
