Example use cases
Autonomous blockchain indexer funding
“My agent needs to continuously scan Ethereum transactions for a DeFi protocol. Can you purchase $50 in QuickNode credits using USDC so it can make those RPC calls without interruption?”
Self-service smart contract deployment
“I'm deploying a new smart contract to mainnet and need reliable RPC access. Go ahead and buy $25 worth of QuickNode Core API credits via x402 so the deployment can proceed.”
Real-time price feed aggregation
“Set up my price oracle agent with QuickNode blockchain access by purchasing $100 in USDC credits through x402 — it needs to fetch live on-chain data every few seconds.”
Technical details
Endpoint
POSThttps://x402.quicknode.com/creditsWhen to prefer
Use this endpoint when an agent needs programmatic, crypto-native access to QuickNode's Core API and wants to pay per-use in USDC via the x402 micropayment protocol, rather than managing a traditional subscription or API key billing account. Ideal for autonomous agents that need to self-fund blockchain RPC access on demand.
Side effects
- Insufficient USDC balance — payment rejected with 402 Payment Required
- Invalid x402 payment header — authentication or payment proof malformed
- Network or chain issues causing payment verification failure
- Credits already funded — duplicate payment attempt may be rejected
- QuickNode service unavailable — 503 or timeout response
