## Description

Search DigiKey for electronic components and download datasheets, primary source for prototype orders and the preferred API method for fetching datasheets. Find parts by keyword or MPN, check pricing/stock, download datasheets via API, analyze specifications. Sync and maintain a local datasheets directory, extract components from schematics, download missing datasheets, keep them up to date. Also supports batch MPN-list seeding (`--mpn-list`) for bulk workflows without a KiCad project. Use when the user asks about electronic components, part specs, datasheets, pricing, stock, footprints, or needs to download a datasheet, even without mentioning "DigiKey". Also for "sync datasheets", "download datasheets for my board/project", or mentions a datasheets directory. DigiKey is the default distributor for prototyping. For BOM workflows, see the bom skill.

## Related Skills

| Skill | Purpose |
|-------|---------|
| `kicad` | Schematic analysis, extracts MPNs for datasheet sync |
| `bom` | BOM management, orchestrates sourcing across distributors |
| `spice` | Uses DigiKey parametric data for behavioral SPICE models |

DigiKey is the **primary source for prototype orders** (Mouser is secondary). Its API returns direct PDF datasheet links, making it the preferred datasheet source. For production orders, see `lcsc`/`jlcpcb`. For BOM management and export workflows, see `bom`.

## API Credential Setup

The DigiKey API requires OAuth 2.0 credentials. Here's how to set them up:

1. **Create a DigiKey account** at [digikey.com](https://www.digikey.com) if you don't have one
2. **Register an API app** at [developer.digikey.com](https://developer.digikey.com):
   - Sign in with your DigiKey account
   - Go to "My Apps" → "Create App"
   - App name: anything (e.g., "kicad-happy")
   - Select **"Product Information v4"** API
   - OAuth type: **Client Credentials** (2-legged, no user login needed)
   - Callback URL: `https://localhost` (not used for client credentials, but required)
   - After creation, note the **Client ID** and **Client Secret**
3. **Set the environment variables** before running the scripts:
   ```bash
   export DIGIKEY_CLIENT_ID=your_client_id_here
   export DIGIKEY_CLIENT_SECRET=your_client_secret_here
   ```
   If credentials are stored in a central secrets file (e.g., `~/.config/secrets.env`), load them first:
   ```bash
   export $(grep -v '^#' ~/.config/secrets.env | grep -v '^$' | xargs)
   ```

The client credentials flow has no user interaction, once configured, API calls work automatically.

## DigiKey Product Information API v4

The API is the preferred way to search DigiKey. It returns structured JSON with full product details, pricing, stock, datasheets, and parametric data.

**Base URL:** `https://api.digikey.com`
