# Image Moderation API > NSFW image classification on a Mojo ViT, $1 per thousand images, no image retention MCP: https://moderate.mojojojo.cc/mcp (JSON-RPC over POST). OpenAPI: https://moderate.mojojojo.cc/openapi.json. Auth: `Authorization: Bearer mj_live_...`; create a key at https://mojojojo.cc/keys. Usage is billed from mojojojo credits. ## Pricing - Images moderated: $0.001 per image (100 free per month) ## Endpoints - `POST /v1/moderations/image` (MCP tool `moderate_image`): Classify images as normal or nsfw. Images are base64-encoded png/jpeg/webp/gif/bmp. ## Limits and measured results - Send the raw image, a multipart field named file, or JSON {"images_base64":[...]}. Up to 8 images, 50 megapixels each. - Returns normal/nsfw probabilities and flagged (nsfw >= 0.5). A binary classifier: it does not detect violence, minors or text. - Logits match PyTorch to 5.5e-06. - Speed: 0.65x PyTorch (about 2 images/s on 2 cores). Images are decoded in memory and never written to disk.
