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-evaluate-multiple-signals-e87748ca -d '<json body>'
```

Example prompt: Can you evaluate RSI (14-period) and MACD signals for BTC on the 1h timeframe from 2024-11-01 to 2024-11-30 using Mangrove's signal engine?

## When to prefer this

Use this endpoint when you need to evaluate multiple technical analysis signals simultaneously for a crypto asset, rather than making separate calls per signal. It is particularly valuable for trading strategies that require cross-signal confirmation or multi-timeframe analysis in a single request. Prefer it over single-signal endpoints when you have 2–20 signals to compute at once.

## Known failure modes

- Missing required fields: symbol/dataset_key, start_date/end_date cause validation errors
- Invalid or unregistered signal name returns an error for that signal
- Unsupported timeframe string causes rejection
- Dataset key not found returns a not-found error
- More than 20 signals in the array may be rejected
- Payment failure or insufficient USDC balance blocks the request

## Output

Returns evaluated results for up to 20 registered technical signals, each with computed values and any relevant metadata such as signal direction, strength, or status across the specified timeframe(s) for the given asset or dataset.
