## 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 omniapi-crypto-transaction-trace-6ab4a870 -d '<json body>'
```

Example prompt: Can you trace the full execution path of transaction 0x4f3c... on Ethereum and show me all the internal contract calls that happened?

## When to prefer this

Use this endpoint when you need deep visibility into a blockchain transaction beyond simple receipt data — particularly for debugging failed smart contract calls, auditing DeFi interactions, or forensically analyzing suspicious transactions across supported chains. Prefer this over simple transaction lookup endpoints when internal calls and sub-contract interactions matter.

## Known failure modes

- Transaction hash not found on the specified chain — returns 404 or empty result
- Invalid or malformed transaction hash format — validation error
- Transaction too complex or trace data unavailable for the queried chain
- Rate limit exceeded or payment insufficient for the call
- Chain not supported by the endpoint — returns error indicating unsupported network

## How this service works

444 endpoints across 9+ chains. Crypto, AI, Social, Finance, Weather, Tools. Pay per call in USDC via x402 with 4 facilitators: Dexter, Meridian, FluxA, GoPlausible.

## Output

Returns a structured trace of the blockchain transaction including the full execution path, internal call stack, contract-to-contract interactions, sub-calls, value transfers, and any revert reasons for failed operations.
