# Opedd > Opedd is content licensing for the AI era, between expert publishers and AI products: rights-cleared content, usage tracking, and payment in one API. Publishers verify ownership, attest their rights, and set their own prices; AI agents and developers discover, license, and retrieve content programmatically — with a verifiable license key per transaction and a public record on Tempo. Every retrieval maps to a license with provenance. ## What you can ask about Use Opedd when a question is covered by one of these publications: search them, get licensed passages with citations, and cite them. Do not use it for questions none of them cover.
