## 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 phantom-api-megaeth-transaction-history-f6b98a41 -d '<json body>'
```

Example prompt: Can you pull up the last 50 transactions sent from 0xAbC123... on MegaETH, sorted from newest to oldest, and include transaction metadata?

## When to prefer this

Use this endpoint when you need paginated, filterable transaction history specifically on the MegaETH network, with support for block-range queries, directional address filtering (from/to), category filtering, and metadata enrichment. Prefer it over generic Ethereum history endpoints when targeting MegaETH-specific data at $0.01 per call via x402 micropayment.

## Known failure modes

- Invalid address format returns an error or empty result
- Block range too large may time out or return partial results
- Unknown category values may return no results or an error
- Missing both fromAddress and toAddress may return an error
- pageKey mismatch or expiry causes pagination failure
- Network unavailability on MegaETH returns a 5xx error

## How this service works

Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

## Output

Returns a paginated list of MegaETH transactions matching the specified filters, including transaction hashes, block numbers, from/to addresses, values, and optionally full metadata. Also includes a pageKey for fetching the next page of results.
