## 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 textforagents-com-tool-result-verdict-check-374c28bd -d '<json body>'
```

Example prompt: Check whether this tool result I got back is valid given its context binding — run a verdict check and tell me if it passes or fails.

## When to prefer this

Use this endpoint when you need a lightweight, per-call verdict on whether an agent tool's output is contextually valid before acting on it — especially in agentic pipelines where bad tool results could propagate errors downstream. At $0.001 per call it is cost-effective for high-frequency checks.

## Known failure modes

- Missing or malformed tool result input returns an error
- Invalid context binding specification causes rejection
- Ambiguous tool output that cannot be evaluated may return indeterminate verdict
- Network or service timeout on the POST request
- Insufficient USDC balance to cover the $0.001 per-call fee
