• On top of that, you can add further filters such as specifying block range where the transactions should have occurred, or address and ID of involved tokens.
• For Tezos blockchain, the API accepts only one wallet address in addresses query parameter. Following query parameters won't have any effect on filtering data: transactionTypes, transactionSubtype, tokenId, blockTo.
• When querying Tezos transactions for a specified wallet or contract address, pagination is supported via pageSize and offset query parameters.
• When querying Tezos transactions for a specified block, pagination is supported via cursor query parameter, by filling in the value from prevPage or nextPage field in the response body.

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.

Get unspent UTXOs for a specific address up to a specific total amount. If you want to prepare a transaction on UTXO-based chains like Bitcoin, you need to enter unspent UTXOs to be able to perform a transaction. By providing ```totalValue``` as a total, our API will return a list of UTXOs that will be enough to cover the transaction.

• Bitcoin - bitcoin / bitcoin-testnet
• Litecoin - litecoin / litecoin-testnet
• Dogecoin - doge / doge-testnet
• Cardano - cardano / cardano-preprod

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.

This operation is used to create a new smart contract on the blockchain. The operation is asynchronous and returns a transaction hash. The transaction hash can be used to query the status of the transaction.
You can create the following types of contracts:

• ERC-20 - Fungible token like USDT
• ERC-721 - NFT collection like BAYC
• ERC-1155 - MultiToken NFT collection

Get the current exchange rate for exchanging fiat/crypto assets.

By default, the base pair (the target asset) is EUR. When obtaining the exchange rate for an asset (for example, BTC), the value returned by the API expresses the amount of EUR that can be currently exchanged into 1 BTC.
