## 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 liquid-agent-polymarket-sol-15m-price-to-beat-dda05b25
```

Example prompt: What's the official SOL price to beat right now on the Polymarket 15-minute up/down market, and how far is the live Chainlink price from it — and how many seconds are left in the window?

## When to prefer this

Use this endpoint when you need the authoritative Chainlink TWAP reference price for Polymarket's SOL 15-minute Up/Down market, especially for verifying settlement prices, monitoring live distance to the price-to-beat, or retrieving historical window outcomes. Prefer this over generic price feeds when you specifically need the Polymarket-matched oracle price rather than just spot price.

## Known failure modes

- Invalid or future unix timestamp in ?start parameter returns error
- Market not yet initialized for current window may return incomplete data
- Chainlink oracle downtime could cause stale or missing price data
- Request outside active market hours may return no live window data

## How this service works

Polymarket SOL 15m Up/Down in one call: the OFFICIAL price to beat (the 60 s Chainlink TWAP before the window, matched to the cent against Polymarket's results), the live Chainlink price and its distance from the price to beat, seconds left, token ids and the market's own prices. ?start=<unix> returns a past window's official settle and outcome. $0.002 USDC. Data, not financial advice.

## Output

Returns a JSON object with: the market slug, asset, timeframe, seconds remaining, status (live/settled), the official price-to-beat (Chainlink 60s TWAP before window), the live Chainlink SOL price, the distance (in USD) between live price and price-to-beat, and Polymarket Up/Down token prices (0-1 probability). For historical queries via ?start=<unix>, returns the settled outcome and official price.
