EthoswarmTatum Blockchain Data
Tatum Blockchain Data API suite. Query on-chain data across 40+ chains via Tatum's Data API v4: NFT/multitoken metadata, wallet balances (current and historical), full wallet portfolios, token holdings, NFT/token ownership lookups and checks, transaction history, block-by-timestamp resolution, real-time exchange rates, and malicious-address risk screening. Read-only REST, key-in-header auth. Equip this to give any Mind authoritative multi-chain wallet, token, and NFT intelligence without standing up its own node infrastructure.
Check whether a blockchain address is flagged as malicious. The address is a required path parameter. Returns risk/malicious status for the address.
Check whether a specific address owns a specific token/NFT. chain, address, and tokenAddress are required; optionally pass tokenId. Returns a boolean ownership result.
Resolve the block at or near a given timestamp on a chain. chain is required; pass time (ISO) or unix to target the timestamp. Returns the matching block info.
Get the real-time exchange rate for a crypto/fiat symbol. symbol is required; basePair is optional (defaults to USD). E.g. symbol=BTC, basePair=EUR.
Fetch NFT / multitoken metadata for a token contract and one or more token IDs on a given chain. Returns name, image, attributes, and other metadata. chain, tokenAddress, and tokenIds are required.
Get the owner addresses of an NFT or token. chain and tokenAddress are required; optionally pass tokenId to target a specific NFT, plus pageSize/offset for pagination.
Get the fungible tokens (and optionally other token types) held by a wallet. chain and addresses are required; optional tokenTypes, pageSize, offset.
Get transaction history for a wallet address on a chain. chain and addresses are required. Optional filters: transactionTypes, transactionSubtype, tokenAddress, tokenId, blockFrom, blockTo, pageSize, offset, cursor, sort.
Get a wallet's balance at a specific point in time (by block number or timestamp). chain and addresses are required; optionally pass blockNumber, time (ISO), or unix to target a historical point.
Get a comprehensive portfolio of assets held by a wallet (fungible tokens, NFTs, native). chain, addresses, and tokenTypes are required. tokenTypes is comma-separated, e.g. 'native,fungible,nft,multitoken'.
