## 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-5m-price-to-beat-e66a6410
```

Example prompt: What's the official SOL price to beat right now on Polymarket's 5-minute up/down market, and how far is the live Chainlink price from it?

## When to prefer this

Use this endpoint when you need the canonical, settlement-matched price to beat for Polymarket's SOL 5-minute up/down market — specifically the 60-second Chainlink TWAP that Polymarket itself uses to settle outcomes. Prefer this over generic price feeds when you need the exact Polymarket-matched reference price, live distance, token prices, and countdown in a single call. For BTC or ETH 5m markets, use the sibling endpoints instead.

## Known failure modes

- Invalid or future unix timestamp in ?start parameter returns an error or empty result
- No active market window found (between windows) may return null or stale data
- Chainlink oracle delay may cause slightly stale live price
- Network or provider outage returns a 5xx error
- Malformed request parameters result in a 400 error

## How this service works

Polymarket SOL 5m 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

A JSON object containing: the official price to beat (60s Chainlink TWAP before the window), the live Chainlink SOL price, the distance between the two, seconds left in the window, the market slug and status, and the current Up/Down token prices on Polymarket. For historical queries via ?start=<unix>, returns the settled price to beat and outcome.
