How this service works
Read-only JSON-RPC access to the Avalanche C-Chain, served by the Pocket Network decentralised supplier set. Pay per request in USDC; no account, no API key.
Output
A JSON-RPC response object containing the 'result' field populated with the requested on-chain data (balance in wei, block object, transaction receipt, log array, hex-encoded contract return value, etc.) or a JSON-RPC 'error' object if the call fails.
Example use cases
DeFi portfolio balance check
“Can you fetch the AVAX balance of 0x742d35Cc6634C0532925a3b844Bc454e4438f44e on Avalanche C-Chain right now using eth_getBalance?”
Smart contract state read
“Call the Avalanche C-Chain contract at 0xB31f66AA3C1e785363F0875A1B74E27b85FD66c7 using eth_call with the encoded data for balanceOf(0xabcd...1234) — I need to know its token balance.”
Transaction receipt lookup
“Look up the transaction receipt for tx hash 0x4e3a3754410177e6937ef1f84bba68ea139e8d1a48ac301791f7e62b7d1d5955 on Avalanche C-Chain so I can confirm it was mined and see the gas used.”
Technical details
Endpoint
POSThttps://agent.pocket.network/v1/avax?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need trustless, decentralised read access to Avalanche C-Chain without provisioning an API key or account — ideal for agents making ad-hoc or low-volume queries billed per-call in USDC. Prefer it over centralised RPC providers (Infura, Alchemy) when censorship-resistance or decentralisation of the node layer matters, and over Pocket's other chain endpoints when the target chain is specifically Avalanche C-Chain (not Ethereum mainnet, Arbitrum, Optimism, etc.).
Side effects
- Invalid or unsupported method name returns a JSON-RPC error code -32601
- Malformed params cause a -32602 invalid params error
- Write methods (eth_sendRawTransaction, eth_sendTransaction) are not supported — returns error as endpoint is read-only
- Node temporarily unavailable from supplier set returns HTTP 503 or timeout
- Insufficient USDC balance / failed x402 payment returns HTTP 402 Payment Required
- Rate limiting if per-request payment not honoured
