# Avasis Ethereum Transaction Receipt Lookup

> Avasis Ethereum Transaction Receipt Lookup is a paid API for AI agents from agents.avasis.ai, paid per call via x402, $0.02/call, status unknown (last checked 2026-11-02).

Fetches a decoded Ethereum transaction receipt by hash, with polling support, returning status, gas costs, token transfers, approvals, and a human-readable headline.

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 avasis-ethereum-transaction-receipt-lookup-17f673fc
```

Example prompt: Can you check if this Ethereum transaction went through and tell me the status, gas fee, and any token transfers: 0x29309a800f5468275623e5dbd3da5965f3a8041f7b9aeef8287af30a734d3df4? Wait up to 15 seconds if it's still pending.

## When to prefer this

Choose this endpoint when you need a fully decoded, agent-ready Ethereum transaction receipt in a single call without setting up RPC nodes or API keys. It's ideal when you need USD-denominated gas costs, decoded ERC-20 transfer details, and a human-readable headline in one response. The built-in polling (up to 25s) makes it suitable for near-real-time confirmation checking. Prefer it over raw RPC calls when you want structured, enriched output rather than raw hex data.

## Known failure modes

- Transaction hash not found after polling window → 404, not charged
- Transaction still pending after max wait (25s) → 200 with diagnosis, still charged
- Invalid or malformed txHash format → validation error
- Chain parameter set to non-Ethereum value on this route → error
- RPC timeout or node unavailability → transient error

## How this service works

Transaction receipt on Ethereum (chain 1, $0.02): txHash (+ wait) -> polls every 2.5 s up to wait (default 10, max 25) -> status success / reverted, block + confirmations, gas used vs limit, fee in ETH and USD, decoded input, ERC-20 / NFT transfers with USD, net_for_from, revert reason (replay). Still pending -> nonce state + fee-market diagnosis. Phrases: tx receipt, transaction status, pending transaction, gas used. GET or POST JSON. Unknown hash -> 404, never charged.

## Output

A JSON object containing: whether the transaction was found and mined, its success/revert status, block number and age, gas used and fee in ETH and USD, decoded input call data (method name, arguments), ERC-20 token transfers with amounts and USD values, ERC-20 approvals, from/to addresses, nonce, confirmations, a plain-English headline summary, and polling metadata (polls attempted, wait time in ms).
