What Ethplorer (BYOK) is for

Ethplorer (BYOK) lets an AI assistant read your own Ethplorer data through the Ethplorer API with a key you supply (Ethplorer API key (the shared test key is freekey)). Read-only: 10 tools (get_last_block, get_token_info, get_address_info, get_transaction_info, get_address_transactions, get_address_history, get_token_history, get_top_token_holders, get_top_tokens, get_new_tokens). 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.ethplorer.io. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Ethplorer. Ethplorer 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:

• "Which Ethereum block has Ethplorer indexed up to?"
• "What is the price and holder count of the token 0xf3db5fa2c66b7af3eb0c0b782510816cbe4813b8?"
• "What ETH and tokens does 0xff71cb760666ab06aa73f34995b42dd4b85ea07b hold?"
• "What did transaction 0x6aa670c983425eba23314459c48ae89b3b8d0e1089397c56400ce2da5ece9d26 do?"
• "What are the latest ETH transactions of this address?"
• "What token transfers did this address make recently?"

What it does

• get_last_block: Get the number of the last Ethereum block Ethplorer has processed.
• get_token_info: Get an ERC-20 token by contract address: name, symbol, decimals, supply, holder count, price, market cap and volume.
• get_address_info: Get an Ethereum address: ETH balance and price, contract creator if it is a contract, and the ERC-20 tokens it holds.
• get_transaction_info: Get one Ethereum transaction: block, time, success flag, sender, recipient, value, gas and decoded function name.
• get_address_transactions: List ETH transactions of an address with time, sender, recipient, value, USD value and success flag.
• get_address_history: List recent token operations (transfers, mints, burns) involving an address, optionally for one token.
• get_token_history: List recent operations of one token: transfers, mints or burns with time, parties and value.
• get_top_token_holders: List the largest holders of a token with address, balance and percentage share.
• get_top_tokens: List the top 50 tokens ranked by trade volume, market capitalization or operation count.
• get_new_tokens: List up to 100 recently created tradable tokens, newest first, with price and holder count (Ethereum mainnet only).

BYOK key

You bring your own Ethplorer Ethplorer API key (the shared test key is freekey) (https://ethplorer.io/wallet/#screen=api). 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.ethplorer.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://github.com/EverexIO/Ethplorer/wiki/ethplorer-api (the API this connector calls, with a BYOK key)

Live from the Ethplorer API (api.ethplorer.io) with a BYOK key; documentation: https://github.com/EverexIO/Ethplorer/wiki/ethplorer-api. 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 Ethplorer. Ethplorer 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 Ethplorer account.

Ethplorer (BYOK) — Privacy Policy

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

What Ethplorer (BYOK) is. Ethplorer (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Ethplorer data: Read Ethereum token info, address balances, token holders, transfers and top tokens from the Ethplorer explorer with your own API key. You bring your own Ethplorer Ethplorer API key (the shared test key is freekey); the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Ethplorer 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.ethplorer.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 Ethplorer 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 Ethplorer receives. The request we make on your behalf, including the key and the arguments, under Ethplorer's own terms and privacy policy. Ethplorer acts at your direction and is the only recipient of the data of your request besides our hosting provider.

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

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

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