Obsidian Data Fetcher

A plugin for Obsidian that allows users to fetch data from multiple sources (REST APIs, GraphQL, gRPC, RPC) and insert the results into notes.

Features

• Support for multiple data sources:
  • REST APIs
  • GraphQL endpoints
  • gRPC services (via REST proxies)
  • RPC services
• Two modes of operation:
  • Directly define queries within notes
  • Predefine endpoints in settings and reference them in notes
• Automatic caching of query results to reduce redundant requests
• Cache expiration settings
• Manual refresh capabilities
• Customizable headers for authentication

Usage

Method 1: Direct Query Definition

Create a code block with the language set to data-query and define your query in JSON format:

​```data-query
{
  "type": "rest",
  "url": "https://api.example.com/data",
  "method": "GET",
  "headers": {
    "Authorization": "Bearer your-token"
  }
}
​```

Method 2: Using Aliases

1. First, define an endpoint alias in the plugin settings
2. Then reference it in your notes:

​```data-query
@my-api-alias
body: {"id": 123}
​```

Configuration

Go to Settings > Data Fetcher to configure:

• Cache duration
• Pre-defined endpoint aliases
