What Tatum (BYOK) is for

Tatum (BYOK) lets an AI assistant read your own Tatum data through the Tatum API with a key you supply (Tatum API key). Read-only: 10 tools (get_exchange_rate, get_ohlcv, get_price_change, get_wallet_portfolio, get_transaction_history, get_transactions_by_hash, get_nft_balances, get_latest_block, resolve_domain_name, get_token_metadata). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.tatum.io. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Tatum. Tatum and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "What is the current ETH price in USD?"
• "Give me the BTC daily candle for 2026-10-01"
• "How much did BTC change in the last day?"
• "What tokens does the wallet 0xd8dA... hold on Ethereum?"
• "Show the latest transfers of wallet 0xd8dA... on Ethereum"
• "What are the transfers in transaction 0xabc... on Ethereum?"

What it does

• get_exchange_rate: Get the current exchange rate of a crypto or fiat symbol in a target asset (default EUR). Costs 20 Tatum credits when the target is fiat, USDT or USDC, 50 otherwise; the free plan only accepts fiat, USDT or USDC targets.
• get_ohlcv: Get one OHLCV candle (open, high, low, close, volume) in USD for a symbol at a time. Costs 50 credits.
• get_price_change: Get the absolute and percentage price change of a symbol over an interval or a time range. Costs 200 credits.
• get_wallet_portfolio: Get a wallet's native, fungible token or NFT balances on one chain. Costs 50 credits.
• get_transaction_history: List a wallet's transactions (native, token and NFT transfers) on one chain, newest first by default. Costs 20 credits.
• get_transactions_by_hash: Look up a transaction by its hash on one chain and return its transfers. Costs 10 credits.
• get_nft_balances: List the NFTs a wallet holds on one chain, with contract, token balances and metadata links. Costs 50 credits.
• get_latest_block: Get the latest block of a chain: number, timestamp, hash and transaction hashes. Costs 10 credits.
• resolve_domain_name: Resolve a blockchain domain name (ENS, Solana and similar) to a wallet address. Costs 20 credits.
• get_token_metadata: Get metadata for NFT or multi-token IDs of a contract: metadata URI and metadata. Costs 10 credits.

BYOK key

You bring your own Tatum Tatum API key (https://docs.tatum.io/docs/authentication). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.tatum.io over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

• https://docs.tatum.io/reference/exchange-rate (the API this connector calls, with a BYOK key)

Live from the Tatum API (api.tatum.io) with a BYOK key; documentation: https://docs.tatum.io/reference/exchange-rate. Endpoints checked against that documentation on 2026-10-16.

What it is not

Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Tatum. Tatum and its logos are trademarks of their owners and are used only to say which service the connector works with. It is read-only: it never creates, changes, sends or deletes anything in your Tatum account.

Tatum (BYOK) — Privacy Policy

Effective 24 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Tatum (BYOK) is. Tatum (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Tatum data: Read multi-chain wallet portfolios, token and NFT balances, transaction history, blocks, name lookups and crypto prices from Tatum with your own API key. You bring your own Tatum Tatum API key; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Tatum call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to api.tatum.io, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Tatum rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What Tatum receives. The request we make on your behalf, including the key and the arguments, under Tatum's own terms and privacy policy. Tatum acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Tatum gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your Tatum data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. Tatum (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at Tatum at any time to end all access.

Children. Tatum (BYOK) is a general-audience service operated by the adult using the assistant, under Tatum's own age rules.

Changes. We will post changes here with a new effective date.
