⚠ Agent card, not A2A. QuickNode serves a machine-readable agent manifest at the A2A discovery path, but it fails a structural check in the A2A 1.0.0 AgentCard object. It is an agent card in spirit rather than in schema — useful for discovery, but an A2A client cannot assume it will parse.

Discovery

An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.

Autonomous Endpoint Provisioning provision_endpoint

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
