Indexed daily since 2026-05-29 across 19 categories. Pull any of it via /v1/index and /v1/movers.

Don't ship raw stats. Ship intelligence.

Every endpoint returns HoodCar's proprietary signals — not just averages. That's the moat competitors can't copy from public sold listings.

Fair Value Engine

A single defensible value per card with a p25–p75 range, min/max, and a per-grade ladder — derived from millions of verified sales.

Buy Score & Verdict

A 0–100 score and a plain-English call — Strong Buy, Accumulate, Hold, Reduce — so apps can act, not just display.

Liquidity Models

How fast a card actually trades, scored from sales velocity and spread — the difference between a price and a fill.

Confidence

Spread-based confidence on every value so downstream models know how much to trust each number.

Price Indexes

Daily category and label indexes since launch — chart the market, not just a single card.

AI Scan & Portfolio

Identify a card from an image and value an entire collection through one consistent intelligence layer.

Intelligence Infrastructure for an entire industry

The category leaders own a layer. HoodCar owns collectibles.
