Example prompt: Can you check the current UMA dispute stage for the Polymarket event at https://polymarket.com/event/example-polymarket-event — I want to know how confident the tracker is, how much time is left, and what percentage of the dispute process is done?

## When to prefer this

Use this endpoint when you need trader-grade, real-time visibility into the UMA dispute resolution lifecycle for a specific Polymarket event — particularly when you need stage confidence scores, time estimates with confidence labels, and activity breakdowns (dispute count, voting rounds, chain events). Prefer this over generic oracle trackers when the user's intent is specifically about Polymarket prediction markets and UMA escalation stages.

## Known failure modes

- Invalid or unrecognized Polymarket event URL or slug returns an error or empty result
- Market not currently in a dispute state may return no active stage data
- Blockchain data unavailability may reduce data completeness score and lower stage confidence
- Network or upstream Polymarket/UMA API outage may cause request failure
- Stale data may be returned if live chain events have not yet propagated

## How this service works

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

## Output

Returns a JSON object with the Polymarket market metadata (title, status, question, resolution), the assessed UMA dispute stage (ID, label, confidence, explanation, completeness score), activity metrics (disputes, chain events, voting rounds, oracle requests), and progress details (time remaining, next event, progress percent, active stage label), plus source, price tier, capability name, and generation timestamp.
