This endpoint provides the sales volume and market caps of specific collections. More collections and sales from different token types are being added over time. Note, from April 2023 onwards, the 90d and all_time values will be returned the same by default.
Currently, this endpoint supports Ethereum, Solana, Polygon, Bitcoin Ordinals, Arbitrum and Optimism. Other chains will be supported over time.
