## 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 achilles-validate-endpoint-2368e01f -d '<json body>'
```

Example prompt: Use ACHILLES to validate agent 'agent-007' performing the action 'trade' targeting 'ETH-USDC' with a value of 500 — I need to confirm this is authorized before execution.

## When to prefer this

Use this endpoint when you need to validate or pre-authorize an autonomous agent action before execution within the ACHILLES platform, especially when operating under the x402 micropayment protocol and DELPHI intelligence framework.

## Known failure modes

- Missing required agent_id returns 400 error
- Invalid or unrecognized agent_id returns unauthorized response
- Malformed action or target string may return validation failure
- Insufficient x402 micropayment balance returns 402 Payment Required
- Network or service unavailability returns 503
