Quickstart.

Your first API call in five minutes — install a client, add a key, search the catalog.

Install a client

Pick your entry point — the CLI, Homebrew, or the MCP server for AI assistants.

# Install the parts CLI (macOS / Linux)
curl -fsSL https://source.parts/cli/install.sh | sh

Add your API key OPTIONAL

You can skip this — parts auth login generates a key for you automatically. Set one manually only for CI or server environments, from your dashboard.

SOURCE_PARTS_API_KEY=your_api_key_here

Authenticate

Generates an API key automatically if you don't have one, and stores it in the system keychain — macOS Keychain, Linux Secret Service, or Windows Credential Manager.

Make your first request

Always send a descriptive User-Agent — the WAF rejects unknown agents.

curl "https://api.source.parts/v1/parts/search?q=ESP32&limit=10" \
  -H "Authorization: Bearer $SOURCE_PARTS_API_KEY" \
  -H "User-Agent: my-app/1.0 ([email protected])"

# ...or the same search with the CLI:
parts search "ESP32" --limit 10
