Indexed daily since 2026-05-29 across 19 categories. Pull any of it via /v1/index and /v1/movers.
Every endpoint returns HoodCar's proprietary signals — not just averages. That's the moat competitors can't copy from public sold listings.
A single defensible value per card with a p25–p75 range, min/max, and a per-grade ladder — derived from millions of verified sales.
A 0–100 score and a plain-English call — Strong Buy, Accumulate, Hold, Reduce — so apps can act, not just display.
How fast a card actually trades, scored from sales velocity and spread — the difference between a price and a fill.
Spread-based confidence on every value so downstream models know how much to trust each number.
Daily category and label indexes since launch — chart the market, not just a single card.
Identify a card from an image and value an entire collection through one consistent intelligence layer.
The category leaders own a layer. HoodCar owns collectibles.
The same verified-sales intelligence powers everything from a single API call to an enterprise dashboard.
Build on the market-data layer.
Proprietary signals, not raw stats.
Dashboards for operators.
Authenticate with x-api-key. Every response is a { meta, data } envelope. Derived analytics only — no raw listings leave the API.
