## 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 primeapi-crypto-transaction-trace-83d5b4c0 -d '<json body>'
```

Example prompt: Can you trace the execution path of this transaction — 0xabc123def456... — and show me all the internal calls and state changes that happened inside it?

## When to prefer this

Use this endpoint when you need to inspect the internal execution details of a specific on-chain transaction — especially for debugging failed transactions, auditing DeFi interactions, or understanding internal token transfers that aren't visible at the surface level. Prefer this over block explorers when programmatic, structured trace data is needed by an agent.

## Known failure modes

- Invalid or malformed transaction hash returns an error
- Transaction not found on the queried chain returns 404-style error
- Network congestion or RPC timeout may cause delayed or empty response
- Transaction still pending (not yet mined) may return no trace data
- Generic input schema means malformed query strings may yield no useful output
