## 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`):

```

Example prompt: Can you pull a market-forensics snapshot for the Polymarket market on the 2024 US presidential election — I want to see the liquidity, freshness, and any resolution-risk flags before I trade?

## When to prefer this

Choose this endpoint when you need a structured, multi-dimensional quality assessment of a specific Polymarket market before trading or monitoring — particularly when you want freshness, liquidity, and resolution-risk bundled into a single forensics snapshot rather than querying Polymarket's raw API directly. It is especially useful for agents automating market screening or due-diligence workflows on prediction markets.

## Known failure modes

- Market not found — invalid or unsupported market identifier returns an error
- Stale snapshot — data may lag real-time Polymarket state depending on refresh cadence
- Payment failure — x402 micropayment of $0.05 USDC not completed results in 402 response
- Rate limiting — excessive calls may be throttled
- Polymarket API unavailability — upstream data source outage causes snapshot failure

## How this service works

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

## Output

A forensics snapshot object containing market freshness indicators (e.g., last-update timestamps, staleness flags), liquidity metrics (e.g., spread, depth, volume), and resolution-risk observations (e.g., ambiguity flags, settlement uncertainty signals) for the queried Polymarket market.
