What Zerion (BYOK) is for

Zerion (BYOK) lets an AI assistant read your own Zerion data through the Zerion API with a key you supply (Zerion API key (used as the Basic auth user name)). Read-only: 11 tools (get_wallet_portfolio, list_wallet_positions, list_wallet_transactions, get_wallet_pnl, get_wallet_balance_chart, list_wallet_nfts, list_tokens, get_token, get_token_price_chart, list_chains, list_gas_prices). 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.zerion.io. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Zerion. Zerion 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 total value of this wallet and how did it change today?"
  • "Which tokens does this wallet hold and what are they worth?"
  • "What were the latest transactions of this wallet?"
  • "What is this wallet's total profit and loss?"
  • "How did this wallet's balance change over the last month?"
  • "Which NFTs does this wallet own?"

What it does

BYOK key

You bring your own Zerion Zerion API key (used as the Basic auth user name) (https://dashboard.zerion.io). 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.zerion.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

Live from the Zerion API (api.zerion.io) with a BYOK key; documentation: https://developers.zerion.io/introduction. 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 Zerion. Zerion 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 Zerion account.
