How this service works
Biggest Federal Reserve probability moves (1h/6h/24h) — The fastest way to see where news is landing in Federal Reserve: active markets ranked by absolute probability change over your chosen window, with volume surge ratios. Same shape as /v1/movers, pre-filtered to Federal Reserve markets.
Output
A ranked list of Federal Reserve prediction market movers, each containing the market slug, question text, current probability (p_now), previous probability (p_prev), absolute probability delta, volume surge ratio, and category — ordered by the magnitude of probability change over the selected window. Also includes response metadata.
Example use cases
Fed rate decision news monitoring
“What are the top 5 Federal Reserve markets that have moved the most in the last hour? I want to see if any big news just hit.”
Daily Fed policy briefing
“Give me the 20 biggest Federal Reserve probability movers over the last 24 hours so I can put together my morning macro briefing.”
High-liquidity Fed market screening
“Show me the top Federal Reserve prediction markets moving over the past 6 hours, but only include ones with a minimum liquidity score of 0.7.”
Technical details
Endpoint
GEThttps://x402-factory.com/v1/movers/fedWhen to prefer
Use this endpoint when you specifically need to surface Federal Reserve policy prediction markets ranked by probability momentum — ideal for macro news monitoring, Fed-focused trading signals, or policy briefings. Prefer this over the generic /v1/movers endpoint when you want results pre-filtered to Fed markets without needing to apply a category filter manually. Choose the 1h window for breaking-news detection, 6h for intraday momentum, and 24h for daily summaries.

- min_liquidity outside 0–1 range returns a 400 error
- No markets match filters returns an empty movers array
- Payment not included or insufficient USDC returns a 402 Payment Required
