## 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 superchain-transaction-explainer-49b659da -d '<json body>'
```

Example prompt: Can you explain what happened in this Ethereum transaction? Here's the calldata: 0x38ed173900000000000000000000000000000000000000000000000002c68af0bb140000... it was on Base chain.

## When to prefer this

Choose this endpoint when you need to decode and humanize raw blockchain transaction data — especially calldata, event logs, or explorer output — into a plain-language explanation. Ideal for DeFi analysis, governance auditing, security review, or user-facing transaction summaries. Prefer this over generic blockchain RPC calls when you need semantic interpretation rather than raw data retrieval.

## Known failure modes

- Malformed or truncated calldata returns an error or incomplete explanation
- Unsupported chain yields no result or generic fallback
- Very long calldata exceeding 8000 character limit is rejected
- Ambiguous input without chain context may produce incorrect decoding
- Unknown or unverified contract ABI may limit explanation depth

## How this service works

Onchain intelligence. Tokenomics, transactions and governance, decoded.

## Output

A structured JSON response containing a jobId, a human-readable explanation of the transaction (decoded function name, parameters, token flows, governance actions, or tokenomics details), and a payment receipt with transaction hash, amount paid, and network.
