Use Crawlora's Alt API endpoints to extract supported public Alt data as structured JSON. This documentation covers 9 active endpoints including Get one card design's population report and recent sales, Search Alt's own live 24/7 auctions, Search Alt's reference card-design catalog, List Alt search filter values, and related APIs. Developers can use these endpoints for monitoring, enrichment, research dashboards, internal data pipelines, and agent-native workflows without maintaining platform-specific scraping code. Each endpoint page documents authentication, request parameters such as asset_id, id, listing_type, cURL examples, response examples, response schemas, errors, credit cost, and Playground testing. Send requests to the Crawlora API with an x-api-key header, review usage and plan limits on pricing, and test safe sample requests in Playground before moving the workflow into production.
Choose an endpoint, send an authenticated request with the x-api-key header, and inspect the normalized JSON response. The examples below use the public Crawlora API base URL and the same endpoint catalog used by Playground.

Get one card design's population report and recent sales
Returns one card design's identity, full population report (across every grading company and grade Alt tracks), and a recent raw sales feed -- the "is this card actually rare, and what does it sell for" data for a specific card design, independent of any single listing. asset_id comes from a prior alt-search/alt-sold-listings/alt-card-search result's asset_id field. recent_sales has no per-transaction grade breakdown -- Alt's own API does not expose one; see alt-sold-listings for per-grade sold prices on specific listings. Credential-free public data from Alt's own GraphQL API.
Searches Alt's own currently live auctions -- the same pool shown on alt.xyz/browse's "Auctions" tab filtered to the Alt source. Unlike alt-search, this never returns another source auction house's listings or Alt's own fixed-price items: it always uses a search key scoped server-side to Alt's own live auction pool. Credential-free public data from Alt's own search backend. See alt-categories for the accepted category/grading_company/sort values.
Searches Alt's reference card-design catalog -- a canonical catalog of card designs (one entry per year/brand/subject/card-number/variety combination), separate from live listings or sales. Useful for finding a card design's asset_id (to feed into alt-asset for a population report and recent sales) without already having a live listing or sale that references it. Credential-free public data from Alt's own search backend.
Returns every accepted value for alt-search/alt-auctions/alt-sold-listings' category, auction_house, grading_company, and listing_type params, plus the sort enum. category/auction_house/grading_company/listing_type are read live from Alt's own current search index via a facets-only query on every call, not a fixed taxonomy -- so this endpoint self-corrects if Alt's aggregator adds a new source auction house, grading company, or category. Credential-free public data from Alt's own search backend.
One listing's full public detail -- title, description, price/bid state, grading info, and images -- normalized across Alt's own native listings and its aggregated external listings. id and listing_type come from a prior alt-search/alt-auctions result. Not every response field applies to every listing_type -- see the field-level notes in this endpoint's markdown doc.
Returns Alt's own category-level price-trend index -- the same data alt.xyz's "Market Trends" page shows: a weekly/monthly/90-day change and a current index value per card category, built from Alt's own sold/valuation data. Credential-free public data from Alt's own GraphQL API.
Searches 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.
Searches Alt's global archive of completed card sales, aggregated across every source auction house its search carries -- the "market data" side of Alt's card-investment-marketplace positioning. This is a separate index from alt-search/alt-auctions, scoped to a rolling recent time window, not a filtered view of live listings. Pass auction_house=Alt to see only Alt's own completed auctions. Credential-free public data from Alt's own search backend. See alt-categories for the accepted category/auction_house/grading_company values.
Returns Alt's biggest price-index movers -- either a cross-subject leaderboard (optionally scoped to one category) or, when subject is set, that one player/character's own trend broken out per category it appears in. category is not strictly validated against alt-categories' list -- this trend index's own category set is broader (e.g. it includes MULTI-SPORT_CARDS). Credential-free public data from Alt's own GraphQL API.
