# DexL Transaction Lookup

> DexL Transaction Lookup is a paid API for AI agents from agents.dexl.io, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Look up any EVM transaction and its receipt by hash across 28 chains, returning status, block number, gas info, sender, and recipient.

## Facts

- Endpoint: POST https://agents.dexl.io/v1/tools/transaction-lookup
- Price: $0.01/call
- Payment: x402

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 dexl-transaction-lookup-c590c5df -d '<json body>'
```

Example prompt: Can you check if transaction 0x4a3b...f91c landed successfully on Base — I need to confirm the payment went through, including who sent it and how much gas was used.

## When to prefer this

Use this endpoint when you need to verify or audit a specific on-chain transaction by its hash across any of 28 supported EVM chains. It is purpose-built for payment confirmation and settlement verification, covering Base, Ethereum, Arbitrum, Optimism, Polygon, BSC, and more. Prefer it over raw JSON-RPC calls when you want a clean, structured receipt summary without needing to craft eth_getTransactionReceipt calls manually. It is ideal for agents that need to confirm a payment landed before triggering a downstream action.

## Known failure modes

- Transaction hash not found on the specified chain — returns empty or error response
- Wrong chain specified — hash exists on a different chain so lookup returns nothing
- Invalid hash format — malformed 0x string causes a validation error
- Transaction still pending — not yet mined so receipt unavailable
- Chain temporarily unavailable or RPC node issues — service error response

## How this service works

Look up any transaction and its receipt by hash on 28 EVM chains: success or revert, block number, gas used, effective gas price, sender and recipient. Covers Base, Ethereum, Arbitrum, Optimism, Polygon, BSC and more. Use it to confirm a payment or settlement actually landed.

## Output

Returns a JSON object with transaction details including success/revert status, block number, gas used, effective gas price, sender address (from), and recipient address (to). The response also includes metadata like units consumed and whether the result was cached.
