## 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 blockrun-polymarket-uma-market-lookup-cf0d5b63
```

Example prompt: Can you fetch the resolution status and outcome data for Polymarket UMA market at contract address 0x1234...abcd?

## When to prefer this

Use this endpoint when you need on-chain resolution or dispute data for a specific Polymarket prediction market identified by its UMA contract address. Prefer this over general Polymarket APIs when you need oracle-level settlement data or are verifying a market outcome programmatically via BlockRun's paid routing layer.

## Known failure modes

- Invalid or zero contract address returns empty or null data
- Market not found for given address returns 404 or empty data object
- Unresolved market returns pending status with no outcome
- Network or RPC errors may cause timeouts
- Zero address (0x000...000) used in this endpoint's own URL may return placeholder/empty response

## How this service works

Pay for the outcome. One endpoint for every model, tool and data source an agent needs — each call priced before it runs, at the best value per dollar. 115 models and 100 data and tool APIs.

## Output

Returns a JSON object containing on-chain data for the specified Polymarket UMA oracle market, including resolution status, outcome data, dispute information, and market metadata associated with the provided contract address.
