# Extract W-2 Data
Tax and finance teams use this recipe to extract W-2 fields from official forms into structured JSON for review, routing, and downstream filing preparation.
## APIs Used
Document Extraction (1 credit per page)
## Prerequisites
You need an Iteration Layer API key. Get one at [platform.iterationlayer.com](https://platform.iterationlayer.com) during the 7-day trial.
For full integration guidance (SDKs, auth, MCP, error handling), see the [Iteration Layer Integration Guide](https://iterationlayer.com/SKILL.md).
## Implementation
```bash
curl -X POST https://api.iterationlayer.com/document-extraction/v1/extract \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
