Check gate eligibility or proof criteria (server-side)
Primary server-side integrator endpoint for access control. Pass gateId from your deployed gate, or explicit verifier/criteria filters. Returns eligible plus matched proof references without exposing private proof payloads.
Headers
CAIP-2 chain reference for non-EVM signature verification (e.g. solana:mainnet)
Signature method hint for non-EVM signatures (e.g. ed25519)
Query Parameters
^0x[a-fA-F0-9]{64}$80^[a-zA-Z0-9:_-]+$1 <= x <= 10001 <= x <= 3650x >= 01 <= x <= 1000EVM chain ID of the asset being checked (e.g. 1 for Ethereum Mainnet, 8453 for Base). Required for asset verifiers (nft-ownership, token-holding, contract-ownership). Not a hub or proof-storage filter.
x >= 1When set, requires ownership-pseudonym proofs to include this namespace (matches verifier data.namespace; legacy proofs without namespace default to neus).
1 - 64^[a-z0-9._-]+$x >= 0Approving account (delegation grantor) for agent-delegation checks; optional filter. Not the agent wallet.
