Image annotation API
One hosted API tagged “annotation”, each also an MCP server for AI agents. Free calls every day to try them; then pay per call with x402 (USDC) or prepaid credits from $5.
- Supervision Draw: Draw detections onto an image with Roboflow supervision's own annotators, over HTTP and MCP. Send a base64 image and detections (boxes in xyxy pixels, optional class_id, confidence, label, polygon) and get back the annotated image plus per-class counts. Annotators: box, round_box, box_corner, circle, dot, ellipse, triangle, label, color, mask, polygon, halo, background_overlay, blur, pixelate, percentage_bar, chained in order. A hosted alternative to installing Python and supervision just to render detection results.
