What Blockscout (BYOK) is for

Blockscout (BYOK) lets an AI assistant read your own Blockscout data through the Blockscout API with a key you supply (Blockscout PRO API key (starts with proapi_)). Read-only: 12 tools (get_network_stats, get_address, list_address_transactions, list_address_token_balances, list_address_token_transfers, get_transaction, list_blocks, get_block, list_tokens, get_token, get_smart_contract, search). 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.blockscout.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Blockscout. Blockscout 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:

• "How busy is the Ethereum network right now and what are gas prices?"
• "What is the balance of vitalik.eth's address on Ethereum?"
• "What are the latest transactions sent from this Ethereum address?"
• "Which tokens does this Ethereum address hold?"
• "What USDC transfers did this address receive recently?"
• "Did transaction 0x5c50... succeed and what did it cost?"

What it does

• get_network_stats: Get a network's headline statistics: total addresses, blocks and transactions, transactions today, average block time, native coin price and market cap, gas prices and network utilization.
• get_address: Get an address or contract: native coin balance, name, ENS name, whether it is a contract and verified, creator, creation transaction, scam reputation and its token details if it is a token.
• list_address_transactions: List the newest transactions of an address (first page, up to 50), optionally only incoming or outgoing, with status, value, fee, method and time.
• list_address_token_balances: List the token balances held by an address (ERC-20, ERC-721, ERC-1155) with token name, symbol and decimals; values are raw integer amounts.
• list_address_token_transfers: List the newest token transfers involving an address (first page, up to 50), optionally by direction, token type or token contract.
• get_transaction: Get one transaction by hash: status, block, time, sender, recipient, value, fee, gas, method, confirmations, result or revert reason and decoded call.
• list_blocks: List the newest blocks of a network (first page, up to 50) with height, time, miner, transaction count and gas use.
• get_block: Get one block by number or hash: time, miner, transaction count, gas used and limit, base fee, size, fees and parent hash.
• list_tokens: List tokens on a network ranked by market cap, holders or fiat value, optionally filtered by name or symbol and token type (first page).
• get_token: Get one token by contract address: name, symbol, decimals, type, holder count, price, market cap, supply and 24-hour volume.
• get_smart_contract: Get a verified smart contract's metadata: name, language, compiler version, optimization settings, license, verification status and proxy type. Source code and bytecode are not returned.
• search: Search a network for tokens, addresses, contracts, blocks or transactions by name, symbol, address, hash or block number (first page, up to 10 results).

BYOK key

You bring your own Blockscout Blockscout PRO API key (starts with proapi_) (https://dev.blockscout.com/). 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.blockscout.com 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.blockscout.com/devs/pro-api-responses-and-routes (the API this connector calls, with a BYOK key)

Live from the Blockscout API (api.blockscout.com) with a BYOK key; documentation: https://docs.blockscout.com/devs/pro-api-responses-and-routes. 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 Blockscout. Blockscout 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 Blockscout account.

Built for: Worldwide. Languages: English.

Blockscout (BYOK) — Privacy Policy

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

What Blockscout (BYOK) is. Blockscout (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Blockscout data: Read blockchain data on 100+ EVM networks (addresses, transactions, blocks, tokens, verified contracts, network stats) through the Blockscout PRO API with your own key. You bring your own Blockscout Blockscout PRO API key (starts with proapi_); the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Blockscout 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.blockscout.com, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Blockscout 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 Blockscout receives. The request we make on your behalf, including the key and the arguments, under Blockscout's own terms and privacy policy. Blockscout acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Blockscout 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 Blockscout 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. Blockscout (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 Blockscout at any time to end all access.

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

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