Overview

Trace.moe finds the exact anime scene matching a screenshot or image you upload, returning the anime title, episode number, and timestamp of the matching scene. It uses video fingerprinting to search a database of thousands of anime episodes. Beginners building anime identification tools or Discord bots will find it straightforward since no API key is required.

💡

Beginner Tip

You can search by either uploading an image file or passing an image URL as the url query parameter. For quick tests, try passing a direct image URL to avoid multipart form setup.
