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 synapse-api-megaeth-token-transfers-efdd7ccc -d '<json body>'
```

Example prompt: Show me all ERC-20 token transfers for the wallet 0xAbC123... on MegaETH, sorted in descending order, limited to 25 results starting from block 1000000 to block 2000000.

## When to prefer this

Use this endpoint when you need token transfer history specifically on the MegaETH network and want block-range filtering, ascending/descending ordering, and built-in pagination via pageKey. Prefer this over generic Ethereum explorers when targeting MegaETH specifically, or when you need programmatic, pay-per-call access without API key signup. It covers multi-contract filtering in a single call.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result set
- Unknown contract address yields no transfers
- Block range where fromBlock > toBlock may return an error or empty list
- Invalid pageKey from a prior request causes pagination failure
- Exceeding maxCount limits may truncate results without warning
- Network-specific errors if MegaETH node is unreachable
- Missing required 'owner' field returns a validation error

## How this service works

## Output

A list of ERC-20 token transfer records for the specified wallet/contract on MegaETH, each containing transaction hash, sender, recipient, token contract address, amount, and block number. Also includes a pagination key (pageKey) for fetching subsequent pages of results.
