Circle launches agent discovery layer
WHAT HAPPENED
The Paypers reports that Circle added a Discovery API to Agent Stack, giving AI agents one public endpoint to search more than 900 service endpoints without an API key or Circle account. Using x402, a service returns price, accepted token and destination in an HTTP 402 response; the agent signs an authorization, a facilitator settles USDC on-chain and the service returns the result.

## Source summary
The Paypers reports that Circle added a Discovery API to Agent Stack, giving AI agents one public endpoint to search more than 900 service endpoints without an API key or Circle account. Using x402, a service returns price, accepted token and destination in an HTTP 402 response; the agent signs an authorization, a facilitator settles USDC on-chain and the service returns the result.
## Why it matters
The launch connects service discovery, machine-readable pricing, delegated authorization and settlement in one agent workflow. Circle also describes spending caps, rolling budgets, whitelists, isolated wallet funding and request-frequency circuit breakers—controls that matter before autonomous payments can be trusted across markets. The report does not establish live transaction volume, merchant quality, dispute handling, chain costs or regulatory availability by country.
