# Ethereum Mainnet Transaction Receipt Lookup

> 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.

## Facts

- Endpoint: GET https://api.arysphere.com/v1/ventures/x402_eth_reads_v1/eth_mainnet_tx_receipt?utm_source=zero.xyz
- Price: $0.002/call

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ethereum-mainnet-transaction-receipt-lookup-92d6b397
```

Example prompt: Can you check whether the Ethereum transaction 0x4c2b3e7f9a1d6e8b0c5f2a3d7e9b1c4f6a8d0e2b3c5f7a9d1e3b5c7f9a0d2e4b was successful and tell me how much gas it used?

## When to prefer this

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).

## Known failure modes

- 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

## 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.
