How this service works
Avalanche C-Chain RPC (chain 43114): JSON-RPC over HTTPS on NodeFlare's own bare-metal nodes. Pay per request in USDC, no account or API key - built for AI agents. All methods including eth_getLogs, eth_call, trace, and debug (archive) - good for indexing, event queries, and simulation. Simple calls $0.001; heavy calls priced by compute units.
Output
A JSON-RPC 2.0 response object containing the result of the requested method — e.g. a hex balance, array of log objects, call return data, transaction receipt, trace array, or debug trace depending on the method called. Errors return a JSON-RPC error object with code and message.
Example use cases
DeFi contract state lookup
“Check the current reserves of the Trader Joe AVAX/USDC liquidity pool on Avalanche by calling getReserves on contract 0xf4003F4efBE8691B60249E6afbD307aBE7758adb.”
Avalanche event log indexing
“Fetch all Transfer events emitted by the USDC contract on Avalanche C-Chain from block 30000000 to 30010000 so I can index them.”
Transaction simulation before sending
“Simulate calling the swap function on a Trader Joe router contract on Avalanche with my wallet address and these params to see if it would revert and how much gas it would use.”
