## 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 pulsescanner-internal-transfers-by-transaction-179a61d5
```

Example prompt: Can you pull up all the internal transfers made within PulseChain transaction 0xabc123...def456? I want to see every sub-call and value movement inside that tx.

## When to prefer this

Use this endpoint when you need to inspect the internal sub-calls and value movements within a specific PulseChain (chain ID 369) transaction, as opposed to only viewing top-level transaction data. It is the right choice when debugging DeFi interactions, auditing contract behavior, or tracing how value flows between contracts within a single transaction.

## Known failure modes

- Invalid or malformed transaction hash returns 400 or empty result
- Transaction hash not found on PulseChain returns 404
- Transaction has no internal transfers returns empty list
- Missing required hash path parameter causes request failure
- Rate limiting or payment failure returns 402 or 429
- Cursor value is stale or invalid, causing pagination errors

## How this service works

Internal value transfers made by one transaction. PulseChain (chain id 369). $0.003 USDC per call.

## Output

A paginated list of internal value transfers (sub-calls) within the specified transaction, including sender address, receiver address, transferred value, call type, and any relevant metadata about each internal call on PulseChain (chain ID 369).
