Grail — the sold-market data API.

What we do

Grail is the sold-market data API for developers, resale platforms, and AI agents. Real sold transactions, reliable pricing intelligence, and structured marketplace data — without maintaining your own collection infrastructure. Give us a keyword and get back up to 240 real eBay completed sales — price, sold date, condition, seller, shipping, and item URL — plus a computed price range (median and min/max).

Why

Pricing anything on eBay usually means manual copy-paste or brittle scrapers. Grail turns that into one dependable API call, so you can build price guides, underwriting tools, dashboards, and autonomous agents on top.

How we work

We run our own acquisition, normalization, caching, and serving. Responses are designed to be compatible with the sold-comps API shape you already know, so existing integrations port over with no changes. Data served from cache is labeled as such.

Endpoints

• GET /v1/scrape — sold comps for a keyword
• POST /v1/scrape/bulk — many keywords in one call
• GET /v1/item — single-listing detail
• GET /rapidapi/scrape-ebay — RapidAPI-compatible endpoint
• MCP — agent-native access
