## 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 disputetracker-polymarket-uma-dispute-metrics-9a78ae14 -d '<json body>'
```

Example prompt: Can you pull the current UMA dispute stage and resolution progress for the Polymarket market at https://polymarket.com/event/example-polymarket-event — I want to know how many disputes have been filed, what phase we're in, and how much time is left?

## When to prefer this

Use this endpoint when you need real-time, structured UMA dispute stage tracking for a specific Polymarket prediction market — especially for trading decisions that depend on knowing whether a market is in initial dispute, escalated to DVM voting, or approaching resolution. Prefer this over manual chain inspection when you need confidence scores, time estimates, and activity rollups in a single call.

## Known failure modes

- Invalid or unknown market slug/URL returns an error or empty market object
- Market not currently in dispute returns null or minimal stage data
- UMA subgraph or on-chain data unavailable causes degraded confidence scores or stale data
- Rate limiting or payment failure returns 402 or 429 status
- Network timeout from upstream oracle data sources returns 503

## How this service works

Trader-grade Polymarket dispute tracker for UMA stages, time confidence, liquidity, and dispute outcomes.

## Output

Returns a JSON object containing: the Polymarket market metadata (title, status, resolution state), the current UMA dispute stage with ID, label, confidence score, and explanation, activity counts (disputes, chain events, voting rounds, oracle requests), resolution progress details (time left label, next event, time confidence level, progress percentage, active stage label), the data source (live or cached), and a generation timestamp.
