Choose this endpoint when you need pay-per-call access to Infura's Linea Mainnet JSON-RPC without committing to a subscription or managing API keys — ideal for agents that make sporadic blockchain queries, need cost-controlled web3 access, or are operating in a x402-native micropayment environment on the Linea L2 network specifically.
Side effects

- Upstream Infura outage or rate limit returns 503 or 429 from the proxy
- Invalid path parameter causes routing failure with a 404 or 500 error
