How this service works
Multi-chain blockchain data API. 7 chains. x402 pay-per-call with USDC on Base.
Output
Returns structured transaction details for the specified hash on the given chain, including sender and receiver addresses, value transferred, block number, timestamp, confirmation status, gas fees, and other chain-specific metadata.
Example use cases
Verify incoming crypto payment
“I just received a payment — can you check transaction 0x4e3b...9a1f on the Base chain and confirm it went through and how much USDC was sent?”
Audit DeFi trade on Polygon
“Look up this Polygon transaction hash 0x7f2a...c8d3 and give me the full details — what wallet sent it, what contract it hit, and what the gas fees were.”
Cross-chain transaction investigation
“I need to trace transaction 0x1c9d...44ba on Arbitrum — can you pull all the on-chain details including the block number and timestamp?”

Endpoint
POSThttps://chain.gpuops.io/v1/transactionWhen to prefer
Choose this endpoint when you need lightweight, pay-per-call transaction lookups across multiple chains without committing to a subscription-based blockchain data provider. Especially useful for agents that only occasionally need on-chain transaction data across heterogeneous chains (up to 7), and where per-call USDC micropayments via x402 are preferable to API key management.
Side effects
- Invalid or malformed transaction hash returns an error or empty result
- Unsupported chain identifier causes a bad request error
- Transaction not yet indexed (too recent) may return not found
- Payment failure via x402 if USDC balance is insufficient blocks the request
- Network-level timeouts if the target chain RPC is slow or unavailable
