Ethereum Mainnet Transaction Receipt Lookup
x402
Ethereum Mainnet Transaction Receipt Lookup is a paid API for AI agents from api.arysphere.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-17).
Fetches a transaction receipt (status, gas used, logs) from Ethereum mainnet by transaction hash via eth_getTransactionReceipt.

How this service works
ARYSPHERE sells AI-written verdicts on Base token contracts (a grade, a one-liner, a roast and the contract's facts) and Base/Ethereum chain reads, paid per call in USDC on Base over x402 v2. No account and no API key.
Output
Returns a JSON object with ok (boolean), the full eth_getTransactionReceipt result including transaction status (0x0 = failed, 0x1 = success), block number, block hash, gas used, cumulative gas used, contract address (if deployment), and an array of decoded logs with topics and data. On failure, returns ok: false with an error message.
Example use cases
Verify DeFi swap completion
“I just sent a Uniswap swap on Ethereum — can you check transaction 0x3a1f9c2e7b4d6a8c0f5e2b3d7a9c1f4e6b8d0a2c3f5e7b9d1a3c5f7b9e0d2a4c and tell me if it succeeded and what logs it emitted?”
Confirm ETH payment received
“Did the Ethereum payment with transaction hash 0x8b2e4f6a9c1d3e5b7f0a2c4e6b8d0f2a4c6e8b0d2f4a6c8e0b2d4f6a8c0e2b4d go through? I need to know the status and which block it landed in.”
Audit smart contract event logs
“Pull the receipt for Ethereum transaction 0x1d3f5b7e9a0c2e4f6b8d0a2c4f6e8b0d2a4c6f8e0b2d4f6a8c0e2b4d6f8a0c2e — I want to see all the event logs that were emitted by the contract.”
Technical details
Endpoint
GEThttps://api.arysphere.com/v1/ventures/x402_eth_reads_v1/eth_mainnet_tx_receipt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative Ethereum mainnet transaction receipt data including confirmation status, gas consumption, and emitted event logs for a specific transaction hash. Prefer this over full transaction lookup when you need post-execution data (status, logs) rather than pre-execution data (input data, value). Ideal for confirming DeFi operations, token transfers, or smart contract interactions completed successfully on Ethereum mainnet specifically (not Layer 2 networks like Base).
Side effects
- Invalid or malformed transaction hash returns an error response
- Transaction hash not found on mainnet (e.g. pending, wrong network) returns null result
- Missing required hash query parameter returns validation error
- Node RPC errors or timeouts cause upstream failures
- Payment failure (insufficient USDC) prevents request from being processed
