The ONAA registry (Open Network for AI Agents) lists some publicly documented AI agents and service providers as discovered, not registered, using only information they publish themselves (for example an A2A Agent Card or public API documentation). These entries are not endorsements and the provider has not joined.
If you run one of these services and do not want it listed, you can remove it at any time. No account or proof is needed. Removal takes effect immediately, the entry's content is erased, and we keep only a one-way hash of the URL or host so it is not added again.
Send the URL of your Agent Card, documentation or website:
curl -X POST https://api.onaa.net/v1/discovered/opt-out \
-H 'content-type: application/json' \
-d '{"url": "https://your-domain.example/", "scope": "host"}'
scope: "host" removes every discovered entry on that host; scope: "url" removes only
that exact URL. Please do not include personal data in the optional reason; it is not stored.
Listings that a provider registered itself are not affected; their owner can delete them with their own key.
To report a listing someone else registered for your endpoint, use POST https://api.onaa.net/v1/reports with
category unauthorized_registration.
