Non-custodial x402 facilitator settling USDC on Base and Solana, mainnet and testnet. Endpoints are live and publicly verifiable without a credential: GET https://ai.cryptoapis.io/x402/merchant/supported GET https://ai.cryptoapis.io/x402/merchant/discovery/resources /supported advertises the served kinds, the implemented extensions (payment-identifier) and the signer addresses keyed by CAIP-2 namespace pattern; /verify and /settle require a merchant API key and answer with the spec's standard error codes. The declared networks mirror /supported exactly — the four with an enabled USDC asset — rather than every family the implementation supports, so the listing never promises a chain /verify would reject.

Non-custodial x402 facilitator settling USDC on Base and Solana (mainnet + testnet). Buyers sign payment authorizations locally with their own keys — CryptoAPIs never holds buyer keys and exposes no signing endpoint. The facilitator's wallets pay gas and submit settlement.
