Developer & Compliance FAQ
What is the cheapest C2PA API for video developers?
LexPixel is built to be the most cost-effective C2PA and invisible watermarking API on the market. By leveraging a proprietary Split-Stream Method that locks the tensor math to a cheap 480p ghost copy—while leaving your 4K video visibly pristine—we cap GPU costs for users, with pay-as-you-go pricing starting at $0.30/min.
Is LexPixel an EU AI Act compliance API?
Yes, LexPixel acts as a drop-in compliance API geared entirely for SMBs and AI agencies operating under the impending August 2026 regulations. We satisfy Article 50 (Limited Risk Systems) transparency requirements by actively injecting Meta VideoSeal forensic watermarks alongside cryptographic C2PA manifests into your AI-generated MP4/WebM content.
How to add invisible watermarks to HeyGen or Kling videos?
Simply generate your video in your preferred provider and pass the resulting video URL directly to LexPixel's /v1/secure-video endpoint. We fetch the file, automatically embed the invisible watermark across frames, and return a tracking URL where you can securely download the final compliant media file.
