The example above is truncated — the real response lists every (scheme, network) pair: exact on all 14 networks, upto and batch-settlement on the 11 EVM networks.

Field	Description
`kinds`	Every supported (scheme, network) pair, with optional scheme-specific `extra` data
`extensions`	Protocol extensions this facilitator advertises
`signers`	Network family → the facilitator’s signing addresses on it

Notable extra values:

batch-settlement kinds carry extra.receiverAuthorizer — the EIP-712 authorizer address that must be committed into escrow channels at deposit time. Always read it from here; see batch-settlement.
The XRPL kind carries extra.areFeesSponsored: false — the payer’s signed transaction pays its own network fee (see Supported Networks).
