FAQ

What does the Float API return?

Float value, paint seed, paint index, sticker positions, wear, and a server-rendered inspect screenshot URL.

Can I query by inspect link?

Yes — pass the inspect URL to /steam/api/float or /float/api/item and you get back the full asset DTO.

How fast are screenshots?

First request renders fresh (~2-5 seconds). Subsequent identical inspect links are cached and return instantly.
