## How to call it through Zero

```sh
zero fetch --capability racingpulse-historical-race-trends-bf1261ff
```

Example prompt: Pull up the draw bias and trainer records for Ascot's 6-furlong sprint on the straight course — I want to find any value angles for this Saturday's handicap.

## When to prefer this

Use this endpoint when you need historical context — draw bias, trainer course records, or statistical value angles — for horse racing, as opposed to real-time going conditions, live speed ratings, or form analysis for individual horses.

## Known failure modes

- Unknown or unsupported racecourse returns 404 or empty result
- Invalid date range yields no historical data
- Rate limiting or payment failure returns 402 or 429
- Sparse historical data for minor tracks may return low-confidence trends
- Missing required parameters returns 400 bad request
