## 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 heurist-mesh-debug-sleep-endpoint-ae76c5b9 -d '<json body>'
```

Example prompt: Run a debug call against the Heurist Mesh debug endpoint and tell me how many seconds it slept for.

## When to prefer this

Use this endpoint when you need to verify that the x402 micropayment flow is working end-to-end, test agent timeout handling with variable latency, or confirm basic connectivity to the Heurist Mesh infrastructure. Not useful for any production data retrieval task.

## Known failure modes

- Timeout if the agent has a short timeout and the sleep lands near 20 seconds
- Payment failure if the x402 USDC micropayment of $0.001 is not processed correctly
- Network error if the mesh.heurist.xyz host is unreachable
- Non-200 response if the x402 payment header is missing or malformed

## How this service works
