Do I need an API key?

Most of OpenFinance MCP works without authentication. Public market data, prices, funding rates, order books, market metadata, and trade previews, is open. Point your agent at the endpoint and start querying. You only need an API key for wallet-scoped tools, which include anything that:
  • Builds a transaction tied to a specific wallet
  • Places, modifies, or cancels an order
  • Reads a wallet’s positions, balances, or order history
  • Signs or submits anything on-chain
If your agent is doing research, monitoring, or analysis, you can skip the key entirely. If it is going to act on a wallet, you need one.

​
Get an API Key

Only follow these steps if you need wallet tools.
1

Sign in

Sign in at openfinance.tech.
2

Open API Keys settings

Open Settings → API Keys.
3

Create the key

Click Create Key, give it a name, and copy the value (it starts with open_).
Treat your API key like a password. It carries the same permissions as your account, including the ability to build and sign trade transactions on connected wallets. Do not commit it to git or paste it into shared chats.

​
How the key is used

The key is passed as x-api-key: open_xxxxx in any of the editor or chat-client configs. Leave the headers object out entirely if you only want public tools.

Pick your editor or chat client from the Coding Agents or Chat Clients sections in the sidebar.
