What is x402 payment?

x402 is a micropayment protocol that lets you pay per API request using USDC on the Base network. When you exceed free tier limits, you can authorize small payments (starting at $0.005) to continue making requests without rate limits.

No! You can start making API calls immediately with no signup or authentication. The free tier gives you 100 calls per day. For higher limits, you can optionally sign in with your Ethereum wallet or use x402 payments.

We support Ethereum mainnet, Base, Optimism, Arbitrum, Polygon, and 15+ other EVM-compatible chains. ENS resolution works on mainnet with CCIP-Read support for off-chain data.
