# EvoLink Moderation content moderation endpoint

`POST /v1/moderations`

- Synchronous endpoint that detects harmful content across 13 dimensions for the input **text** and/or **image**
- The response returns a unified summary via the `evolink_summary` field with `risk_level` / `flagged` / `violations` / `max_score` / `max_category`

**Core capabilities**:
- **Multimodal moderation**: supports text-only, image-only, and combined text + image input
- **13 categories**: harassment, hate, sexual, violence, self-harm, illicit, sexual/minors, and more
- **Risk grading**: each category has its own medium / high thresholds, providing differentiated judgement based on sensitivity (the red-line category sexual/minors uses the strictest thresholds)
- **Explainable**: the response returns both per-category `category_scores` and a simplified `evolink_summary` — you can use either depending on your needs

**Input limits**:
- At most 1 image per request (split into concurrent requests if you need to moderate multiple images)
- Images must be provided as HTTPS URLs

**Typical usage**: see the examples below, covering the three typical scenarios — text-only, text + image, and image-only.
