Quicknode Blockchain Agent

Multi-chain blockchain infrastructure agent. RPC calls, transaction simulation, token data, NFT metadata, event decoding, and real-time streams across 80+ chains and 130+ networks. Autonomous account and endpoint provisioning via x402 or MPP, plus pay-per-request RPC via x402 or API key.

Skills

• 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.
