## 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-evidence-readiness-api-b00ad0ae -d '<json body>'
```

Example prompt: Can you check the current UMA dispute stage and time-left estimate for this Polymarket market — https://polymarket.com/event/example-polymarket-event — and tell me whether it's been escalated to DVM voting yet?

## When to prefer this

Choose this endpoint when you need structured, trader-grade intelligence on the UMA dispute resolution lifecycle for a specific Polymarket prediction market — particularly when you need stage ID, time estimates, and dispute activity counts in a single call. Prefer this over manual on-chain lookups or generic blockchain explorers when you want parsed, confidence-scored stage data and human-readable time labels without building your own UMA event indexer.

## Known failure modes

- Invalid or unknown Polymarket event URL or slug returns an error or empty result
- Market not found on Polymarket returns a 404-style error
- Market has no active dispute so stage data may be null or minimal
- Network or chain indexing lag may cause stale data with low data completeness score
- UMA DVM voting in progress may result in low time confidence labeled as 'estimated'
- Rate limiting or payment failure via x402 protocol returns 402 or auth error

## How this service works

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

## Output

A JSON object containing the market metadata (title, status, resolved outcome), the current UMA stage with a confidence score and explanation, activity counts (disputes, chain events, voting rounds, oracle requests), and a progress block with time-left labels, next event label, time confidence, progress percentage, and active stage label. Also includes source, price tier, capability identifier, and generation timestamp.
