## 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 contract-event-logs-polygon-saylor-innovations-86d54dd1
```

Example prompt: Pull the event logs for Polygon contract address 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 so I can see what on-chain events it has emitted.

## When to prefer this

Use this endpoint when you need on-chain event logs specifically from a Polygon-network smart contract. Prefer it over Base or BSC siblings when your target contract is deployed on Polygon (MATIC network). Ideal for auditing ERC-20 transfers, NFT mints, DEX swaps, or any other contract-emitted events without running your own Polygon node.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract address with no emitted events returns empty logs array
- Rate limiting or quota exceeded returns an HTTP error
- Network-side issues with Polygon RPC may cause timeout or partial data
- Non-contract (EOA) address may return empty or unexpected results

## How this service works

Contract Event Logs (polygon). Polygon contract event logs: raw logs for a contract, optional ?topic0= event filter, up to 2,000 blocks, newest first, up to 200 rows.

## Output

Returns a list of event log entries emitted by the specified contract on the Polygon network, including event topics, data payloads, transaction hashes, block numbers, and log indices.
