How this service works
Multi-chain blockchain data API. 7 chains. x402 pay-per-call with USDC on Base.
Output
Returns a standard JSON-RPC response object containing the result field with blockchain data (e.g., balance in wei, block object, transaction receipt, contract return value) or an error object with code and message if the call fails.
Example use cases
DeFi portfolio balance check
“Look up the current token balance for wallet 0xAbC1234567890 on the Polygon network — I need to know how much MATIC they're holding right now.”
Smart contract state query
“Call the Polygon smart contract at 0xDeFi5678 using eth_call to read the current totalSupply value from its ABI.”
Transaction confirmation lookup
“Check whether my Polygon transaction 0xTxHash9999 has been confirmed and give me the block number it landed in.”

Endpoint
POSThttps://chain.gpuops.io/v1/rpc/polygonWhen to prefer
Choose this endpoint when you need direct JSON-RPC access to the Polygon network and want pay-per-call microtransaction pricing with USDC rather than a subscription. Ideal for agents that make sporadic or low-volume Polygon queries and want to avoid monthly API key commitments. Well-suited for multi-chain workflows where GPUOps also covers other chains under the same payment model.
Side effects
- Invalid JSON-RPC method name returns error code -32601
- Malformed params array causes -32602 invalid params error
- Payment failure or insufficient USDC balance returns HTTP 402
- Rate limiting may occur under high call volume
- Network congestion on Polygon may increase latency
- Invalid contract address returns empty result or revert error
