Mnemo Protocol provides an embedding-vector provenance and verification API that lets developers embed watermarks into vectors and later verify their origin. It supports pay-per-verify payments via x402 on Base or MPP on Tempo, offers SDKs, and targets use cases like RAG, fraud detection, threat intelligence, and regulated AI. The service is hosted at api.trymnemo.com and documented with OpenAPI, SDKs, and detailed agent protocols.
