CardIntel

One spine. Two ways in.

An app for collectors and the API underneath it for people who would rather build their own. Both read the same rows out of the same database.

Public beta

The developer API is live and rate limited per key. The collector app is read only. Saved watchlists, price alerts, portfolio tools and paid consumer plans are marked planned below because they are planned, not shipped. Nothing on this page can charge a card today.

The app, for collectors

Every sold comp plotted, the suspicious ones flagged with evidence, and a fair-value band you can inspect. One avoided bad buy pays for the year.

Free

Look up a card, see the basics.

Consumer billing is not live, so every paid feature above is marked planned. Founder pricing for early list members when it opens.

The developer API, for builders

The same data the app runs on, as clean REST with an OpenAPI 3.1 schema. Cards, sets, price history and fair value across eight TCGs plus sports comps. The free tier is keyed rather than anonymous, so your quota is yours and not your ISP's.

Plus sports sold comps and active listings from eBay and Fanatics Collect — the same spine the consumer app reads.

Endpoints on every tier
  • GET /v2/games
  • GET /v2/cards
  • GET /v2/cards/{id}
  • GET /v2/cards/{id}/prices
  • GET /v2/games/{game}/sets
  • GET /v2/market/movers
  • GET /v2/me
  • GET /v2/health

Send X-Card-Intel-Api-Key. Every route except /v2/health needs a key of any tier — anonymous calls get a 401. The whole surface draws from one shared budget per key, so the quota is a real quota, not per-endpoint.

Quotas above are the values the API enforces today. Paid tier names and prices are provisional — nothing is purchasable yet.

Limits above are the values the limiter enforces today, not a target. Read the API docs.

Questions

Can I pay you today?
No. Checkout is not live. Billing is wired on the backend but not switched on, so every paid plan here is a waitlist entry. We will email you when it opens. Nothing is charged until you choose to subscribe.
How do I get an API key?
Ask. Free-tier keys are issued by hand while self-serve signup is being built. Tell us what you are building. The key goes in an X-Card-Intel-Api-Key header, and GET /v2/me tells you which tier and limits you resolved to.
What happens when I hit the limit?
HTTP 429. The free tier enforces 60 requests/minute and 1,000 requests/day, both counted per key across the whole /v2 surface. /v2/health is open and does not draw from your budget.
Is this financial advice?
No. Card Intel surfaces probabilistic, evidence-backed market signals and fair-value estimates. Every signal is confidence-banded and disputable. You decide.
Where does the data come from?
Completed sales from the venues that are live today, which is 2 of the 18 marketplaces in our source registry: eBay and Fanatics Collect. Publisher and marketplace price feeds cover the TCG side. Venues come online one at a time under source-policy gates, and the full list of what is live against what is only registered is on the methodology page.
What makes a card flagged?
Patterns like wash trading, shill bidding and manufactured scarcity, each with the evidence and a confidence band. Flags never name people and are removable on dispute.
