Reverse Trace
Identify the source of images and videos by running multiple reverse search APIs in parallel and synthesizing results into a confidence-ranked report. Each engine contributes a different signal — web entity matching, AI geolocation, multimodal LLM identification — and the orchestrator merges them because no single API reliably covers all identification scenarios.
Prerequisites
At least one API credential must be set. Missing keys cause the orchestrator to skip that engine, not crash.
| Engine | Env Var | Free Tier | Signal |
|---|---|---|---|
| Google Vision | GOOGLE_APPLICATION_CREDENTIALS or ADC |
1K/mo | Web entities, matching pages, similar images, best-guess labels |
| Picarta (geospy) | PICARTA_API_KEY or GEOSPY_API_KEY |
Yes | Lat/lng, city, country, confidence score |
| Gemini | GOOGLE_API_KEY or GEMINI_API_KEY |
Yes | Media type, title, season/episode, characters, actors |
