Get tokens from a collection

10 credits per API call

Get all NFTs (ERC-721 and ERC-1155) and multitokens (ERC-1155 only) of your favorite collections! Our API lets you search for all tokens on:

  • Celo - celo / celo-testnet
  • Ethereum - ethereum / ethereum-sepolia
  • BNB (Binance) Smart Chain - bsc / bsc-testnet
  • Polygon - polygon / polygon-mumbai

To get started:

  • Provide a chain name and comma-separated list of collection addresses. Our API will return relevant information about each token, including its name, description, image, and more.
  • Aside from relevant information about each token, the response also contains metadata (they can, however, be excluded by setting excludeMetadata to true).
  • If not specified, the API returns results for all supported types of tokens (nft, multitokens), but you can also choose to filter only one tokenType.

Get specified events
20 credits per API call


Get all events on given addresses and / or in the requested block range on the following blockchains:


    

  • Celo - celo / celo-testnet
    • 

  • Ethereum - ethereum / ethereum-sepolia
    • 

  • BNB (Binance) Smart Chain - bsc / bsc-testnet
    • 

  • Polygon - polygon / polygon-mumbai
    • 



To get started:


    

  • To improve response times and obtain specific data, it is recommended to use proper filtering techniques. Please provide a chain name and a combination of filters that will accomplish this (at least block range or contract addresses must be specified).
    • 

  • It is possible to specify multiple contract addresses at once by passing them as a comma separated string.
    • 

  • If block range is not specified, the API attempts to go through all available blocks, which may result in a timeout error.
    • 

  • It is recommended to filter only one specific type of events, which comes with built-in decoding for all the supported types.
    • 

  • It is, however, also possible to filter by signature hashes, which can be passed together as a comma separated string.
    • 



As noted above, aside from general info and hashed event data, the API also decodes them for you in case you filter by one of the following supported event types:


    

  • tokenTransfer: All transfers of fungible tokens (including stablecoins) and NFTs as per ERC-20 and ERC-721 standard.
    • 

  • multitokenTransfer: All transfers of multitokens (both single transfers and batch transfers) as per ERC-1155 standard.
    • 

  • stablecoinTransfer: Refers to the transfer of specific stablecoins on the mainnet. Typically, the top 10 to 16 stablecoins on each chain according to CoinMarketCap are included. If the contractAddresses parameter is also used in the filter combination, any tokens specified in it will also be included in the list.
    • 

  • uniswapTrade: Provides all swap events that occur on both Uniswap V2 and V3. In some cases, it may not be possible to map the swapped amounts to specific tokens. As a result, certain decoded data such as token amounts might be missing or in the original big number format. This will be indicated by the response parameter partiallyRaw: true.

    • 



To get started:


    

  • Provide a chain and address you want to list unspent UTXOs for. If available, our API will return information about the unspent UTXOs for a specific address. API traverses latest 200k incoming transactions.
