How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

Output

Returns a JSON object with an 'ok' boolean indicating success, a 'paid' boolean confirming x402 USDC payment was processed, and the token symbol for the queried chain.

Example use cases

Resolve chain token for DeFi agent

“Can you look up the native token symbol for the Ethereum mainnet? I need it to display the correct currency label in my DeFi dashboard.”

Validate token symbol before swap

“Before I execute this cross-chain swap, can you confirm the native token symbol for Optimism so I make sure I'm referencing the right asset?”

Populate chain metadata in app

“I'm building a multi-chain wallet and need the native token symbol for the Polygon network — can you fetch that for me?”
