Alt API endpoint
Use Crawlora's Alt search API to extract supported public Alt data as structured JSON. This page includes request parameters, cURL examples, response schema, error behavior, credit cost, and a Playground link for testing before integration.
/alt/searchSearches Alt's universal aggregator index -- live auction and fixed-price listings from Alt itself and every other source auction house its search carries (eBay, Fanatics Collect, Pristine Auction, Goldin, CardHobby, Memory Lane) -- by free-text query, category, source auction house, grading company, and listing type, in a caller-selected sort order. Only currently-live listings are returned; see alt-sold-listings for completed sales. Credential-free public data from Alt's own search backend. See alt-categories for the accepted category/auction_house/grading_company/listing_type/sort values. Developers commonly use this endpoint for data enrichment, monitoring, research dashboards, internal automation, and agent-native workflows that need repeatable structured public web data. Authentication uses the documented Crawlora headers, and usage is metered with the credit cost shown on this page.
Request parameters are generated from the active endpoint catalog. Required values must be sent before Crawlora can call the upstream public web data source.

This endpoint is executed through Crawlora's managed scraping infrastructure.
- `results[].auction_house` tells you the listing's actual source — a result is not necessarily an Alt listing. - `alt_value` (Alt's own estimated market value) is only populated for Alt's own native listings. - `bid_count`/`watch_count` reflect Alt's own aggregator tracking and may be `0` for external listings Alt doesn't track engagement on.
