# x402-factory Federal Reserve Probability Movers > x402-factory Federal Reserve Probability Movers is a paid API for AI agents from x402-factory.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15). Returns the Federal Reserve prediction markets with the biggest absolute probability changes over a chosen 1h, 6h, or 24h window, ranked by momentum with volume surge ratios. ## Facts - Endpoint: GET https://x402-factory.com/v1/movers/fed - Price: $0.02/call - Payment: x402 - Status: unknown - Last checked: 2026-09-15 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/x402-factory-federal-reserve-probability-movers-7215ef98 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_6KENdOj7JMC8uO4OwNDia Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability x402-factory-federal-reserve-probability-movers-7215ef98 ``` Example prompt: Show me the top 10 Federal Reserve prediction markets with the biggest probability moves over the last 6 hours, including their volume surge ratios. ## When to prefer this 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. ## Known failure modes - Invalid window value (not '1h', '6h', or '24h') returns a 400 error - limit out of range (must be 1–50) returns a 400 error - 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 - Service downtime or data feed lag returns a 5xx error ## 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. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET" ], "type": "string" }, "queryParams": { "type": "object", "required": [], "properties": { "limit": { "type": "integer", "default": 20, "maximum": 50, "minimum": 1 }, "window": { "enum": [ "1h", "6h", "24h" ], "type": "string", "default": "24h" }, "category": { "enum": [ "politics", "economics", "weather", "crypto", "sports", "science-tech", "entertainment" ], "type": "string" }, "min_liquidity": { "type": "number", "maximum": 1, "minimum": 0, "description": "Minimum liquidity_score (0–1)" } } } }, "additionalProperties": false }, "output": { "type": "object", "required": [ "type" ], "properties": { "type": { "type": "string" }, "example": { "type": "object", "required": [ "data", "meta" ], "properties": { "data": { "type": "object", "required": [ "movers" ], "properties": { "movers": { "type": "array", "items": { "type": "object", "required": [ "slug", "question", "p_now", "p_prev", "delta", "volume_surge_ratio", "category" ], "properties": { "slug": { "type": "string" }, "delta": { "type": "number" }, "p_now": { "type": "number", "maximum": 1, "minimum": 0 }, "p_prev": { "type": "number", "maximum": 1, "minimum": 0 }, "category": { "type": "string" }, "question": { "type": "string" }, "volume_surge_ratio": { "type": "number" } }, "additionalProperties": false } } }, "add … (truncated) ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "data": { "movers": [ { "slug": "fed-hike-september-2026", "delta": 0.0237, "p_now": 0.0488, "p_prev": 0.0251, "category": "economics", "question": "Will the Fed raise rates at the September 2026 FOMC meeting?", "volume_surge_ratio": 1.07 }, { "slug": "fomc-dot-plot-median-shift-2026-09", "delta": -0.0171, "p_now": 0.5666, "p_prev": 0.5837, "category": "economics", "question": "Will the September 2026 FOMC dot plot shift its median rate path?", "volume_surge_ratio": 1.01 }, { "slug": "fed-chair-replaced-2026", "delta": -0.0113, "p_now": 0.0783, "p_prev": 0.0896, "category": "economics", "question": "Will the Fed chair be replaced or step down in 2026?", "volume_surge_ratio": 1.03 }, { "slug": "fed-rate-cut-2026-09", "delta": -0.0013, "p_now": 0.7312, "p_prev": 0.7325, "category": "economics", "question": "Will the Fed cut rates at the September 2026 FOMC meeting?", "volume_surge_ratio": 0.99 } ] }, "meta": { "docs": "https://x402-factory.com/docs/probability.movers.fed", "sources": [ "kalshi", "polymarket" ], "version": "1.0.0", "endpoint": "/v1/movers/fed", "data_mode": "live", "freshness": "realtime", "request_id": "req_00000000", "generated_at": "2026-08-21T03:58:58.142Z" } } } ``` ## More - Live health (JSON, refreshed every minute): https://www.zero.xyz/c/x402-factory-federal-reserve-probability-movers-7215ef98/health.json - [Zero catalog index](https://www.zero.xyz/llms.txt) - [Other services from x402-factory.com](https://www.zero.xyz/host/x402-factory.com/llms.txt)
