# Overview

Contractag exposes two primary endpoints for working with contract fields.

| Endpoint                | Method | Description                                                                                             |
| ----------------------- | ------ | ------------------------------------------------------------------------------------------------------- |
| `/fields`               | `POST` | Upload a PDF and trigger field extraction. Returns a `documentId`, field list, and processing metadata. |
| `/fields/{document_id}` | `GET`  | Retrieve the complete extraction result for a processed document, optionally filtered by page.          |

All endpoints are namespaced under the base URL `https://api.contractag.dev`. Requests must include an API key obtained via email onboarding.

Use the sidebar to dive into request/response details for each route.

<Tip>
  Every endpoint page now ships with an interactive API Playground. Authorize
  once, send live requests, and grab example snippets right inside the docs. See
  `api/playground` under **Get Started** for a quick tour.
