## Known failure modes

- Service unavailable if the Cloudflare tunnel (trycloudflare.com) is inactive or expired, returning a 502 or connection error
- Empty or malformed catalog if the upstream provider has not populated the service registry
- Stale catalog data if the provider has not updated the registry to reflect current utility offerings
- Rate limiting or blocking if the endpoint is called excessively from a single agent

## How this service works

Free machine-readable catalog for two paid agent utilities: Base USDC settlement proof and x402 resource repeat-demand versus one-shot usage analysis.

## Output

A machine-readable JSON catalog listing two paid agent utility services: (1) Base USDC settlement proof — details on how to obtain cryptographic or on-chain proof of a USDC payment settlement; and (2) x402 resource repeat-demand vs one-shot usage analysis — metadata describing how to determine whether an x402-gated resource is accessed repeatedly or as a single use. Each entry includes pricing, endpoint descriptions, and relevant metadata for agent consumption.
