Zerion API MCP

official

Get onchain wallet data on Ethereum, Solana, and all major EVM chains

What can you do with Zerion API MCP?

  • Search Zerion documentation — Ask your AI assistant questions about Zerion API endpoints and get answers pulled from the full docs.
  • Generate integration code — Request scripts that fetch wallet data, such as a Python script for transaction history filtered to trades.
  • Look up endpoint filters — Ask which filters are available on a given endpoint, like the positions endpoint.
  • Reference the OpenAPI spec — Have your AI tool consult the OpenAPI spec while writing code, without copy-pasting docs.

Documentation

Model Context Protocol (MCP) server

Connect Claude, Cursor, and other AI coding tools to Zerion API docs through the Model Context Protocol server for in-editor answers and code generation.

Zerion API docs are available as a Model Context Protocol (MCP) server. Once connected, your AI tool can search the full documentation and OpenAPI spec while generating code. No copy-pasting needed.

Connect via MCP

[tab] Claude Code

Run this in your terminal:

claude mcp add --transport http zerion-api https://developers.zerion.io/mcp

The Zerion docs will be available as a tool in all Claude Code sessions.

[tab] Cursor

Open the command palette (Cmd+Shift+P) → "MCP: Edit Config", then add:

{
  "mcpServers": {
    "zerion-api": {
      "url": "https://developers.zerion.io/mcp"
    }

}

[tab] VS Code

Create .vscode/mcp.json in your project:

{
  "servers": {
    "zerion-api": {
      "type": "http",
      "url": "https://developers.zerion.io/mcp"
    }
  }
}

[tab] Claude Web

  2. Click Add custom connector
  3. Name: Zerion API, URL: https://developers.zerion.io/mcp
  4. Use the attachments button (+) in any chat to access it

What you can ask

Once connected, you can ask your AI assistant things like:

  • "How do I get a wallet's token positions on Ethereum?"
  • "Write a Python script that fetches transaction history and filters for trades"
  • "What filters are available on the positions endpoint?"

The AI will search the Zerion docs in real time to give you accurate, up-to-date answers.

Open in AI assistants

You can also open any documentation page directly in an AI chat for quick questions:

Claude Paste any docs page URL into Claude for API questions and code generation. ChatGPT Use ChatGPT to explore endpoints and generate integration code.

[!TIP]

For the best experience, use the MCP integration instead of copy-pasting. It gives the AI access to the full docs and API spec, not just one page at a time.
