Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 mangrove-developer-signal-parameter-validator-a84bfcd6 -d '<json body>'
```

Example prompt: Before I fire off the 'market_alert' signal, can you validate that the parameters I've set up are correct and flag any errors?

## When to prefer this

Use this endpoint when you need to verify signal parameters before actually submitting or executing a Mangrove signal, especially in automated workflows where bad parameters would cause downstream failures. It is the right choice for pre-flight checks, debugging signal config errors, and building validation gates in agent pipelines on the Mangrove platform.

## Known failure modes

- Signal name not found — returns errors indicating unknown signal
- Missing required parameters — errors array lists each missing field
- Malformed parameter types — errors describe type mismatches
- Invalid signal_name path variable — may return 404 or validation error
- Empty parameters object where required fields exist — errors flagging all missing required keys

## How this service works

## Output

Returns a JSON object with a boolean 'valid' field indicating whether the supplied parameters are acceptable for the named signal, and an 'errors' array listing any validation failures or missing/malformed fields when validation does not pass.
