## Facts

## 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 vibesprings-bazaar-category-trends-c1ca92ee
```

Example prompt: Pull the last 14 snapshots of Bazaar trend data for the 'weather' service tag — I want to see how active listings, price distribution, and call volume have been moving.

## When to prefer this

Use this endpoint when you need time-series trend intelligence about a specific Bazaar API service category — particularly for tracking listing momentum, price evolution, and call volume growth. Prefer this over generic search endpoints when you need historical snapshots rather than a point-in-time listing query.

## Known failure modes

- Missing required 'tag' query parameter returns validation error
- Window value outside 7–30 range may return error or be clamped to defaults
- Unknown or misspelled tag name may return empty snapshot array
- Payment not processed (402) if x402 payment header is missing or insufficient
- Rate limiting or network timeout on slow snapshot computation

## How this service works

Fetches historical metrics, active listings share, price distribution, and call volume momentum for a specific Bazaar service tag over a snapshot series.

## Output

Returns a time-series snapshot array for the specified Bazaar tag covering: active listing share percentage, price distribution buckets, call volume momentum indicators, and historical metric deltas across the requested snapshot window (7–30 periods).
