## 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 infiniterb-poly-signals-0173591f
```

Example prompt: Pull the latest infinitERB poly signals and show me which markets have the highest confidence YES or NO outcomes with their edge estimates.

## When to prefer this

Use this endpoint when you need structured, quantified trading signals for prediction markets with explicit confidence scores and basis-point edge estimates. It is particularly valuable when you want AI-generated directional views backed by reasons like order-book imbalance rather than raw market data you must interpret yourself.

## Known failure modes

- Invalid or malformed properties filter returns empty signals array
- API returns 402 if payment is not properly attached
- Network timeout if the signal computation takes too long
- Empty signals array if no markets currently meet the signal criteria
- Malformed JSON response if server-side error occurs

## How this service works

infinitERB: poetry, philosophy, and objects from the middle — where knowing meets unknowing, and love brings the color.

## Output

A JSON object containing a count of signals and an array of signal objects, each with an outcome (Yes/No), a direction (YES/NO), a confidence score (0-1), an estimated edge in basis points, the associated market question, and an array of human-readable reasons supporting the signal.
