A plain HTTP API.

Send a file — or a link — and get a verdict with the confidence behind it. Works for images, video, and audio.

100 free checks, 30 requests/min — no card required. The key is shown once and stored only as a hash; when the free quota runs out you'll get HTTP 402 and can upgrade from the pricing page.

Built for trust, measured for real.

Every number below comes from held-out testing — generators the model never saw in training, photos from sources it never learned from.

generator families covered, Sora to Midjourney
Generator-disjoint evaluation, July 2026. When the signal is ambiguous, Tayanch says "uncertain" — never a confident guess.
Images, video, and audio
One endpoint family handles stills, clips, links, and audio — each response includes the verdict, a probability, and a confidence.
Link analysis
POST a URL to /analyze/url and the server fetches the media (SSRF-guarded) and runs the same pipeline — social previews resolve automatically.
Calibrated thresholds
Verdicts are tuned per use case, so you can trade recall for a lower false-positive rate.
Simple integration
REST over HTTPS, JSON responses, and API-key auth via the X-API-Key header.
