# List networks

> List the onchain networks enabled for this environment.

`GET /v1/agent-api/onchain-networks`

Neither the SDK nor the CLI calls this endpoint, so you'll need to send a signed
request yourself. See [Authentication](https://docs.catena.com/api.md#authentication) for how requests are
signed. The published contract lists live networks only; a sandbox organization
gets `base-sepolia` and `arc-testnet`.
