## 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 datapackvibe-ethereum-event-log-decoder-21825c2d -d '<json body>'
```

Example prompt: Can you decode this Ethereum event log for me? Topics: ["0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef","0x000000000000000000000000abcdef1234567890abcdef1234567890abcdef12","0x000000000000000000000000fedcba0987654321fedcba0987654321fedcba09"] and data: "0x000000000000000000000000000000000000000000000000016345785d8a0000" — tell me what event this is and what each parameter means.

## When to prefer this

Use this endpoint when you have raw Ethereum event log topics and data and need to decode them into human-readable event names and typed parameters offline — without querying an RPC node, Etherscan, or any external blockchain service. Ideal for transaction receipt parsing, debugging, auditing, or building tools that need fast, stateless log interpretation.

## Known failure modes

- Malformed or truncated topics/data returns a decode error
- Unknown event signature (topic[0] not recognized) returns an unrecognized event error
- Mismatched ABI encoding (wrong parameter count or type) returns a parse failure
- Missing required body fields returns a validation error
- Ambiguous or incomplete hex strings cause decoding failures

## How this service works

Decode Ethereum event logs the caller pastes - topics and data into a named event with typed parameters. Input-in/answer-out: no chain lookup, no invented values.

## Output

Returns the decoded event name and a list of named, typed parameters with their values — all derived from the ABI-encoded topics and data provided, with no on-chain or external lookups performed.
