Endpoint
GEThttps://prediction-bot-iggf.onrender.com/shift?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to understand how sentiment has *changed* over time for a prediction market question, rather than just the raw current score. It is best when you want to detect momentum, reversals, or news-driven sentiment shifts on Polymarket or Kalshi markets based on X (Twitter) activity.
Side effects
- Missing required query parameter 'q' returns an error
- Unrecognized or malformed market question may return null or empty scores
- No cached score available if question is new or never previously queried
- Service cold start on Render.com may cause latency or timeout
- Question text not matching any Polymarket or Kalshi market returns no data
