## When to prefer this

Choose this endpoint when you need authentic, wash-trading-filtered demand signals for x402 API services — specifically to discover which services real AI agents are buying, compare category-level activity, or research pricing benchmarks. Prefer it over raw marketplace listings when buyer-count ranking and trend data matter more than supply-side metadata.

## Known failure modes

- No services match the keyword or category — returns empty top list and zero stats
- Category name misspelled or not in directory — returns zero results with no error
- 'top' parameter too large may return fewer results than requested if supply is limited
- Snapshot may be stale if the underlying data pipeline has not refreshed recently
- Service may be unavailable on Render free-tier cold start, causing slow or failed response

## How this service works

## Output

Returns a structured response including: a list of top services matching the query (with URL, name, category, USD price, 30-day USD volume, unique buyers in 30 days, 7d vs 30d trend, and 24h uptime), a category-level breakdown (category name, service count, volume, unique buyers), aggregate stats (total matched services, median price, buyer-service pairs in 30 days), a natural-language summary and verdict, snapshot timestamp, attribution, and disclaimer — all with wash trading filtered out.
