POSThttps://synapse-api-brown.vercel.app/api/linea/rpcWhen to prefer
Choose this endpoint when you specifically need to interact with the Linea (ConsenSys zkEVM Layer 2) blockchain and want pay-per-call pricing via x402 without managing your own RPC node or subscription. Ideal for agents needing occasional or low-volume Linea RPC calls without committing to a monthly RPC provider plan.
Side effects
- Invalid RPC method name returns error object with code -32601
- Malformed params array causes parse or invalid params error
- Network congestion may cause timeout or slow response
- Payment failure (402) if USDC balance insufficient
- Linea node unavailability returns 503 or connection error
- Unsupported method returns method not found error
