Parameters
Parameter	Description
`cursor` query · string · optional	An opaque cursor from a previous response's `nextCursor`, for the next page. It only pages the chain and collection it was issued for; an empty one, or one over 2048 characters, is a 400 (enforced after the API-key gate).
`chain` path · string · required	ETH, BNB or BASE. SOL, STABLE, RHC and ARC return 400: no wired source lists a collection's traits there. CELO, ARB, OP and SCROLL return 400 here.
`address` path · string · required	The NFT collection's contract address.

Response fields

A JSON response. Every field is always present; null means the value could not be established, never zero.
