This is a screen shot of a Pokemon app a user is building using @CardSightAI which highlights our raw card scanning abilities perfectly.

Just take the picture! 📸 We got you!

No "put the card in the box", no perfect lighting, no solid backgrounds, no "one card at a time". 💪

[CardSight AI, Inc. @CardSightAI]

You don't need to train a vision model. Claude doesn't either.

I don't usually post video content, but showing off our new streaming trading card identification technology called for it! 📸

I won't quit my day job to be a Twitch streamer anytime soon, but we're building some of the coolest tech in the hobby! @CardPurchaser @CardSightAI

[CardSight AI, Inc. @CardSightAI]

Rounding it out, three new endpoints for catalog/search:

→ GET /v1/release-calendar (upcoming + recent releases)
→ GET /v1/catalog/fields (field definitions with usage counts)
→ ?field=KEY:VALUE filtering on catalog/search

Come build something awesome! 750 free calls/month at https://t.co/gvPuLGuZ9Z

April has been big at CardSight AI! 🔥

→ Pokémon catalog is live (20,000+ cards)
→ 130+ new identifiable sets across Baseball, Football, Basketball, Hockey
→ identify endpoint got serious upgrades
→ Over 8.5M cards in the catalog, and counting...

Highlights 🧵

[CardSight AI, Inc. @CardSightAI]

One identify call now does what used to take two.

Descriptions, structured fields, and alternative matches come back inline when the model is uncertain. No follow-up GET to render a full result screen.

Bonus: card images support transparent PNGs now. Rounded Pokémon corners render right.

Add identification to your app. 750 free calls/month at https://t.co/gvPuLGuZ9Z

Our @TAGgrading order is back and these slabs are 🔥

Great experience start to finish! The transparency TAG brings to grading is exactly what this hobby needs. Love seeing companies that do it right.

At @CardSightAI, transparency is core to what we build too. Accurate identification, honest pricing, no black boxes. Love being part of an ecosystem where other companies share that standard.

Which is your favorite?
