How this service works
Polymarket BTC 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 market slug, asset, timeframe, seconds left in the window, live status, the official Chainlink TWAP price-to-beat, the current Chainlink BTC price, the distance (in USD) between the live price and the price-to-beat, and Polymarket's current up/down token prices. For historical queries (with ?start= parameter), returns the settled price-to-beat and outcome for that window.
Example use cases
Live BTC position monitoring during active window
“Check the current BTC 5m Polymarket window for me — what's the official price to beat, where is BTC trading right now, and how far off is it? How much time is left?”
Historical BTC 5m window settlement lookup
“What was the official settle price and outcome for the BTC 5-minute Polymarket window that started at Unix timestamp 1790652300?”
Polymarket BTC arbitrage signal check
“Pull the current Polymarket BTC 5m up/down token prices and the distance from the price to beat — I want to see if there's a pricing discrepancy worth acting on before the window closes.”

Endpoint
GEThttps://api.liquidagent.ai/v1/polymarket/btc-5m?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the exact, officially-matched Chainlink TWAP price-to-beat for Polymarket's BTC 5-minute Up/Down market — not just a raw price feed. It is the single authoritative source for the reference price Polymarket uses to settle results, combined with live price, distance, time remaining, and market token prices in one call. Prefer this over generic price feeds when you need settlement-grade accuracy aligned to Polymarket's own methodology.
Side effects
- Invalid or future unix timestamp in ?start= returns an error or empty result
- Market not yet opened for the current window returns no data
- Chainlink feed latency may cause brief staleness in the live price
- Network or API downtime returns a 5xx error
- Payment of 0.004 USDC not provided or failed results in 402 Payment Required
