}| Field | Meaning |
|---|---|
| kinds[] | One entry per accepted combination of x402 version, scheme and network. Arcus accepts exact on Arc mainnet and testnet. |
| extensions[] | Protocol extensions in use. Currently empty. |
| signers | Relayer addresses keyed by network pattern. The same wallet settles on every Arc network. It only pays gas and never receives funds. |
The x402 server SDK calls this endpoint on startup to check that its registered schemes are supported. See the Quickstart for the server setup.
