## 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 pipe0-withzero-xyz-pipe0-pipes-request-validator-d7b53fab -d '<json body>'
```

Example prompt: Before I actually run my Pipe0 workflow, can you validate this pipes request payload against Pipe0 to make sure it's correctly structured and won't fail — no charge needed, just a proof check?

## When to prefer this

Use this endpoint to pre-flight validate a Pipe0 pipes request before committing to a paid workflow execution. Ideal when building or debugging Pipe0 workflow payloads, or when you want to confirm request structure is correct at zero cost before running the actual pipe.

## Known failure modes

- Invalid or malformed request body returns a Pipe0 validation error in the data field
- Pipe0 service unavailable results in a non-200 response
- Unrecognized pipe fields may cause Pipe0 to reject the payload
- Missing required Pipe0-native fields result in validation failure response

## How this service works

Validate a Pipe0 pipes request against Pipe0. Proof route; no Zero charge.

## Output

Returns a raw JSON response from Pipe0 wrapped in a 'data' field, indicating whether the pipes request payload is valid and accepted by Pipe0.
