Déja. doesn't just use the Synth API — it's built entirely around it. Every trade signal, every bet recommendation, every Kelly-sized position comes from Synth's probabilistic output.
Synth runs 1,000 Monte Carlo price path simulations for BTC, ETH, and SOL. We compare Synth's probability distribution against Polymarket's implied odds. When they diverge by 15%+, that's a tradeable edge.
We query Synth across three timeframes (15-minute, hourly, daily) for each asset. The API endpoint /insights/polymarket/up-down/{timeframe}?asset={asset} returns synth_probability_up, polymarket_probability_up, current_price, and market window times.
Synth's probability estimate feeds directly into a half-Kelly bet sizing formula: f* = (bp - q) / 2b. This recommends optimal bet amounts based on the AI's confidence vs. market odds, capped at $5–$100 for safety.
Edge strength is classified as Strong (25%+) or Moderate (15-25%). The direction (UP/DOWN) is determined by the sign of the edge: positive = Synth thinks UP is underpriced, negative = DOWN is underpriced.
A cron job queries all asset/timeframe combinations via Synth API every 15 minutes. Signals exceeding the 15% threshold trigger Telegram notifications with the full signal context and a deep-link to execute the trade instantly.
GET /insights/polymarket/up-down/{timeframe}?asset={asset}
Authorization: Apikey {SYNTH_API_KEY}
Response: {
slug, current_price, start_price,
synth_probability_up, // ← Synth's Monte Carlo output
polymarket_probability_up, // ← Market's implied odds
synth_outcome, // "Up" or "Down"
event_start_time, event_end_time
}
Edge = synth_probability_up - polymarket_probability_up
