An AI Mind is a persistent, agentic AI with its own identity, long-term memory, and the ability to act on your behalf. Unlike a chatbot that forgets the conversation as soon as you close the tab, a Mind keeps a continuous memory of what you care about, who you work with, and what it's been asked to do. It can browse, send email, manage a wallet, and perform tasks in the background while you're away.

How is an AI Mind different from ChatGPT or other AI assistants?

Most AI assistants are reactive — you ask, they answer, the context disappears. An AI Mind is autonomous: it has standing instructions, ongoing relationships, and goals it can pursue without you in the loop. You can equip it with skills, tools, and apps from the Bazaar so it actually does things in the world (book meetings, monitor markets, send updates) rather than just describing how to do them.

What can my Mind actually do?

Out of the box, a Mind can read and write email, search the web, and remember everything you tell it. From there, what it can do depends on which skills, tools, and apps you equip from the Bazaar — there are integrations for calendar, social, on-chain wallets, research, scheduling, writing, code, and more. Skills are composable, so a single Mind can wear multiple hats over time.

How does memory work?

Every Mind has long-term memory built in — it remembers prior conversations, decisions, and context across days, weeks, and months. There's no private mode toggle: a Mind that forgets isn't useful as an assistant. You can instruct a Mind to forget specific facts, and you can audit what it knows, but the persistent memory is what makes it function more like a colleague than a search bar.

Do I need a crypto wallet to get started?

No. You can sign up with just an email address and awaken a Mind in under a minute. Your Mind can manage a wallet for you later if you want it to handle on-chain activity, but it isn't required to use the platform.

Awakening a Mind is free. You pay for cognition — the AI thinking your Mind does on your behalf — either via subscription or by topping up credits. Skills, tools, and apps in the Bazaar are also free to equip at launch; some advanced integrations may carry their own costs from third-party providers.

App Tools

CheckMaliciousAddressGET

Check whether a blockchain address is flagged as malicious. The address is a required path parameter. Returns risk/malicious status for the address.

CheckOwnerGET

Check whether a specific address owns a specific token/NFT. chain, address, and tokenAddress are required; optionally pass tokenId. Returns a boolean ownership result.

GetBlockByTimeGET

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.

GetExchangeRateGET

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.

GetMetadataGET

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.

GetOwnersGET

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.

GetTokensGET

Get token / collection details for a specific contract on a chain via Tatum Data API v4 (/data/tokens). chain and tokenAddress are required. Optionally pass tokenId to target a specific NFT within the collection. Use 'native' as tokenAddress for the chain's native currency. NOTE: this endpoint returns details ABOUT a token contract — it is NOT a 'tokens held by a wallet' lookup; for wallet holdings use GetWalletPortfolio.

GetTransactionHistoryGET

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.

GetWalletBalanceByTimeGET

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.

GetWalletPortfolioGET

Get a comprehensive portfolio of assets held by a wallet (fungible tokens, NFTs, native) via Tatum Data API v4. chain, addresses, and tokenTypes are required. IMPORTANT: tokenTypes accepts ONLY one of these exact values: 'native', 'fungible', or 'nft,multitoken' (nft and multitoken MUST be passed together as the single literal value 'nft,multitoken'). Do NOT comma-join all four types — 'native,fungible,nft,multitoken' is rejected. To cover multiple types, call once per accepted value.

Overview

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. It gives your AI agent 10 built-in tools, including check malicious address, check owner and get block by time. Apps are free to equip, and once equipped your AI Mind can use Tatum Blockchain Data automatically while it works. Tatum Blockchain Data is currently equipped on 21 Minds.
