How this service works
API Gateway: Ethereum RPC (Ankr)
Output
Returns the standard Ethereum JSON-RPC response object from Ankr's node, including result or error fields — e.g. block data, account balance in hex, transaction receipt, gas estimate, or broadcast confirmation depending on the RPC method called.
Example use cases
Example prompt
“Can you query the Ethereum mainnet to get the current ETH balance of address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 using eth_getBalance with block tag 'latest'?”
Technical details
Endpoint
POSThttps://httpay.xyz/api/gateway/eth-ankr/%7B*path%7D/*When to prefer
Choose this endpoint when you need direct Ethereum mainnet JSON-RPC access on a pay-per-call basis without managing an API key or subscription — ideal for agents that make occasional or bursty Ethereum queries and want to pay micro-amounts per call rather than commit to a plan. Prefer over Infura or Alchemy endpoints when using x402 payment flow or when key management is undesirable.
Side effects
- Invalid JSON-RPC method returns error response
- Malformed request payload returns 400
- Insufficient USDC payment returns 402
- Ankr node timeout or unavailability returns 503
- Invalid Ethereum address format causes RPC-level error
- Transaction rejected by network due to low gas or nonce mismatch
