How this service works
Polymarket ETH 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 in the current window, status (live/settled), official price to beat (60s Chainlink TWAP before window), live Chainlink ETH price, distance between live price and the price to beat, and current market prices for up and down tokens. For historical queries (via ?start= param), returns the settled price to beat and final outcome.
Example use cases
Live ETH market threshold check
“Tell me the current Polymarket ETH 15-minute price to beat, how far the live price is from it, and how much time is left in this window.”
Historical window settlement lookup
“What was the official settlement price and outcome for the Polymarket ETH 15m up/down window that started at unix timestamp 1790652300?”
Automated trading signal monitor
“Every 30 seconds, check the Polymarket ETH 15m price to beat and alert me when the live ETH price is within $20 of the threshold and there are fewer than 60 seconds left.”

Endpoint
GEThttps://api.liquidagent.ai/v1/polymarket/eth-15m?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the exact official Polymarket ETH 15-minute Up/Down settlement reference price (the Chainlink 60s TWAP) alongside live price tracking and market token prices in a single call. Prefer it over manual Chainlink queries when you need the precise price matched to Polymarket's own settlement logic, or over Polymarket's own API when you need the oracle price and distance gap pre-computed.
Side effects
- Invalid or future unix timestamp in ?start= returns error or empty outcome
- Market not yet open or between windows may return no active market data
- Chainlink oracle delay may cause slight lag in live price
- Network or payment failure (x402) results in 402 Payment Required
