How this service works
Read-only JSON-RPC access to zkSync Era, the ZK rollup on Ethereum, served by the Pocket Network decentralised supplier set. Pay per request in USDC; no account, no API key.
Output
A standard Ethereum JSON-RPC response object containing the result field populated with the requested blockchain data (balance in wei, block object, transaction object, receipt, log array, gas estimate in hex, etc.) or an error object with code and message if the call fails.
Example use cases
Check wallet balance on zkSync Era
“Can you look up the ETH balance for address 0x1234...abcd on zkSync Era right now?”
Fetch transaction receipt for settlement
“I need the full transaction receipt for tx hash 0xdeadbeef...cafe on zkSync Era — did it succeed and how much gas did it use?”
Read smart contract state on zkSync
“Call eth_call on the zkSync Era contract at 0xAABB...CCDD with the encoded data for balanceOf(0x1111...2222) and return me the result.”
Technical details
Endpoint
POSThttps://agent.pocket.network/v1/zksync-era?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need permissionless, keyless read access to zkSync Era blockchain data and are comfortable paying per-request in USDC via the x402 protocol. It is ideal for agents that need to query zkSync Era state without managing API keys or node infrastructure, and when decentralisation and censorship resistance of the supplier set matter. Prefer alternatives (e.g. Alchemy, Infura) if you need write access, WebSocket subscriptions, or zkSync-specific extended RPC methods not in the standard Ethereum set.
Side effects
- Invalid JSON-RPC method name returns error code -32601 (Method not found)
- Write methods (eth_sendRawTransaction) rejected as endpoint is read-only
- Malformed params returns error -32602 (Invalid params)
- Non-existent block hash or tx hash returns null result
- Payment failure or insufficient USDC balance blocks the request with HTTP 402
- Rate limits from the Pocket Network supplier set may cause transient failures
