Etchv

Etchv is an API that embeds invisible watermarks in images, PDF files and video, so that each recipient can receive a uniquely marked copy and a leaked file can be traced back to its source. It offers a REST API, software development kits for six languages, an MCP server for AI assistants, and storage options on Amazon S3, Google Cloud Storage and Azure. Its pricing page lists monthly plans before tax: Launch at $19 for 250 credits and images only, Growth at $49 for 1,000 credits, Scale at $99 for 2,500, Business at $499 for 15,000 with single sign-on, and custom Enterprise pricing, with 20% off annual billing and a seven-day trial with 200 credits. The operating company and location are not stated on the site. The maker presented it on Hacker News on 8 October 2026. Buyers should ask how marks survive compression, cropping and re-encoding, and where originals are processed.
