Circle has launched the Discovery API, which allows users to search for all x402 compatible services supporting USDC cross-chain payments through a single public endpoint. This includes categories such as market data, web search, and prediction markets. The API can be called without an API key or account, and the query results are returned in structured JSON format, containing payment information such as payment networks, token addresses, amounts, and service descriptions. Users can automatically verify and call services through an AI Agent without the need to read documentation, and payments can be completed via on-chain x402 transfers or Circle Gateway for gas-free small settlements.
