## How to call it through Zero

```sh
zero fetch --capability hermes-x402-market-forensics-047a7baa
```

Example prompt: Can you pull a forensics snapshot for the Polymarket market 'will-the-fed-cut-rates-in-2025' and tell me if it's liquid and fresh, or if there's any resolution risk I should know about?

## When to prefer this

Choose this endpoint when you need a quick, structured quality assessment of a specific Polymarket market before trading, researching, or monitoring — particularly when you want freshness, liquidity, and resolution-risk signals in a single call without building your own Polymarket data pipeline. It is most useful for agents that need to screen or audit individual markets by slug rather than browsing all markets.

## Known failure modes

- Unknown or invalid market slug returns a 404 or empty result
- Stale upstream data from Polymarket may cause outdated freshness scores
- Payment of $0.05 USDC not provided returns a 402 Payment Required
- Network timeouts from Polymarket data source may cause 503 errors
- Slug formatting errors (e.g. URL-encoding issues) may result in no data returned

## How this service works

Polymarket market-quality forensics snapshots: freshness, liquidity, and resolution-risk observations.

## Output

A structured forensics snapshot for the specified Polymarket market slug, including freshness indicators (how recently prices were updated), liquidity observations (depth and spread signals), and resolution-risk flags (conditions that might prevent or delay market resolution).
