# EVM Transaction Status

> EVM Transaction Status is a paid API for AI agents from bess-x402.onrender.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-30).

Returns the status, block, confirmations, gas, fees, and token transfers for an EVM transaction hash across Ethereum, Base, Arbitrum, Optimism, and Polygon.

## Facts

- Endpoint: GET https://bess-x402.onrender.com/v1/crypto/tx?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402
- Status: unknown

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_r7AgHH4xsaOFz_1Dz9xlZ

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 evm-transaction-status-441bec3d
```

Example prompt: Can you check if this Ethereum transaction went through and tell me the confirmation count, fee paid, and any token transfers: 0x4e3a3754410177e6937ef1f84bba68ea139e8d1e7d1a9f0a8c2e0c8d5f6a1b2?

## When to prefer this

Use this endpoint when you need to confirm whether a specific EVM transaction has settled, determine its confirmation count, inspect fees (including L1 fees on rollups like Base and Optimism), or see ERC-20 token transfers associated with a hash. It covers five major EVM chains and auto-searches if no chain is provided, making it the best single-call option for multi-chain transaction verification without needing separate per-chain queries.

## Known failure modes

- Transaction hash not found on any supported chain — returns not found or empty result
- Invalid hash format (not 0x + 64 hex chars) — returns validation error
- Transaction still pending — status returned as 'pending' with zero confirmations
- Chain specified is not supported — returns error for unsupported chain value
- Network or RPC provider outage may cause timeout or incomplete data

## How this service works

Status of an EVM transaction by hash: pending, success or failed, block, confirmations, timestamp, from/to, value, gas used, fee (plus L1 fee on Base/Optimism) and ERC-20 token transfers. Searches Ethereum, Base, Arbitrum, Optimism and Polygon if no chain is given. Use to confirm a payment settled.

## Output

Returns a JSON object with transaction status (pending, success, or failed), block number, number of confirmations, timestamp, from and to addresses, ETH/native value, gas used, total transaction fee, L1 fee (on Base/Optimism), and a list of ERC-20 token transfer events. If no chain is specified, the service searches across Ethereum, Base, Arbitrum, Optimism, and Polygon automatically.
