## 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 synthora-polymarket-resolution-watch-a0f7789c -d '<json body>'
```

Example prompt: Show me all Polymarket markets resolving in the next 3 days with at least $5000 in 24h volume — up to 50 markets — and flag any with contested or undecided UMA resolutions.

## When to prefer this

Use this endpoint when you need a real-time snapshot of Polymarket prediction markets approaching resolution, especially when UMA oracle risk (disputed or proposed resolutions) is a concern. It is purpose-built for Polymarket + UMA and returns pre-aggregated risk signals not available from generic prediction market APIs. Prefer it over scraping Polymarket directly or querying UMA separately when you need combined resolution status and market metrics in a single call.

## Known failure modes

- Invalid days value outside 0-60 range returns validation error
- Limit outside 1-100 range rejected
- No markets found for the specified window returns empty array with count 0
- Upstream Polymarket API unavailability causes timeout or error response
- min_volume filter too high returns zero results silently

## How this service works

Polymarket resolution watch: markets ending within N days (default 7) with UMA resolution status (proposed/disputed), UMA bond and reward, hours to resolution, last price, 24h volume, liquidity and a uma_risk flag for contested or undecided resolutions.

## Output

A JSON object containing a list of up to 100 Polymarket markets expiring within the specified window, each with: market slug, question text, end date, current YES price, 24h USD volume, liquidity, UMA resolution status (proposed/disputed), UMA bond and reward amounts, hours until resolution, and a boolean uma_risk flag. Also includes aggregate counts of total markets returned and how many carry UMA risk.
