## 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 oblique-markets-bazaar-category-heat-change-feed-906a7119 -d '<json body>'
```

Example prompt: Pull me the latest bazaar category heat changes — I want rank changes and price changes for DeFi and NFT categories, up to 50 records, and resume from my last cursor if I have one.

## When to prefer this

Choose this endpoint when you need a continuous, resumable stream of bazaar category heat movements with stable cursor-based pagination — especially when differentiating between added, removed, rank-changed, and price-changed events matters. Prefer it over snapshot endpoints when you need incremental change detection rather than a full state dump, and when filtering to specific categories or bounding result size is required.

## Known failure modes

- Invalid or expired cursor returns an error requiring a fresh feed start
- Unknown category names in the categories array may return empty results or an error
- Exceeding max_changes bounds may result in truncated responses
- Network or payment authorization failures return a 402 or 4xx error
- since_snapshot references a snapshot that no longer exists in the feed window
