## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability httpay-xyz-18652f15 -d '<json body>'
```

Example prompt: Can you show me all the x402-enabled services available right now — I want to see what APIs I can call with micropayments, including their categories and pricing?

## When to prefer this

Use this endpoint when an AI agent needs to discover what x402-compatible APIs exist, explore micropayment-enabled services by category, or check the current pricing and status of known x402 services. Prefer this over manual web searches when building agentic workflows that need to dynamically discover callable pay-per-use APIs.

## Known failure modes

- No services returned if directory is empty or all services are offline
- Payment failure if $0.01 USDC is not provided via x402 header
- Stale data if directory has not been recently updated
