## 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 bizintel-api-ebay-product-trends-bc0c6695 -d '<json body>'
```

Example prompt: What's the average eBay selling price for an iPhone 13 right now — pull the latest trend data including how many listings were checked.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call eBay market price estimate without setting up an API key or OAuth flow. It is ideal for one-off resale valuations, pricing intelligence, or inventory benchmarking where a real-time eBay data snapshot is sufficient. Prefer it over scraping or full eBay API integration when low setup overhead and micro-payment billing (USDC on Base) are acceptable tradeoffs.

## Known failure modes

- Unsupported or ambiguous product query may return supported:false with low or no price data
- Very niche products with few listings may return a low confidence rating or sparse listings_analyzed count
- Overly generic queries (e.g. 'phone') may return imprecise or averaged results
- Payment failure via x402/USDC may prevent the call from completing
- Network timeout on the Cloudflare Worker may result in a 5xx error with no result

## How this service works

Parses active and completed listings on eBay to determine average resale pricing trends.

## Output

Returns a JSON object with the average sale price of the queried product on eBay, the number of listings analyzed to derive that estimate, a confidence rating (e.g. 'high'), the data freshness date (month/year), a 'supported' boolean indicating whether the query was resolvable, any warnings, and a disclaimer about informational use only.
