## Getting Started

Make your first request to any endpoint below.

### 3. Read computed fields

When an endpoint supports a computed field and the required source inputs are present, the unified response includes that optional field. Depending on the endpoint, optional fields can include `engagement_rate`, `language`, `content_category`, and `estimated_reach`. See [Computed fields](/docs/computed-fields.md) for formulas, clamping rules, and null semantics.

## Endpoints

## Notes

- All endpoints use `GET` method with query parameters
- Authentication via `x-api-key` header
- Responses follow the unified SocialCrawl schema
