How this service works
Live probability: Will the next US GDP print show growth? — Stable evergreen URL for a recurring question: Will the next US GDP print show growth? Auto-resolves to the current market instance and rolls forward on resolution, so the answer is always about the next occurrence. Response adds current_slug and rolls_to_next_at to the standard probability shape.
Output
Returns a JSON object with the aggregated probability (0–1) that the next US GDP print will show positive growth, per-venue breakdowns from Kalshi and Polymarket (each with implied probability, 24h volume, and liquidity score), divergence between venues, 1-hour price move, the current market slug, resolution date, resolution criteria summary, and the timestamp at which the evergreen URL will roll to the next market instance.
Example use cases
Macro briefing for morning report
“Pull the latest market-implied probability that the next US GDP print will be positive, and tell me how much the odds have moved in the last hour.”
Monitor recession risk in real time
“Keep an eye on the prediction market odds for positive US GDP growth and alert me if the probability drops below 50%.”
Compare Kalshi vs Polymarket on GDP
“What's the difference in implied probability between Kalshi and Polymarket right now for the next US GDP print being positive, and which venue has more liquidity?”
Technical details
Endpoint
GEThttps://x402-factory.com/v1/evergreen/next-gdp-print-positiveWhen to prefer
Use this endpoint when you need a stable, always-current URL for US GDP growth probability without having to track individual market slugs. It is ideal for automated monitoring, dashboards, or agents that need to poll GDP sentiment repeatedly without managing market rollovers. Prefer this over venue-specific APIs when you want a cross-venue consensus (Kalshi + Polymarket) with divergence signals in a single call.
Side effects
- No active GDP market found — may occur briefly between resolution and next market creation
- Stale data if upstream prediction market APIs are delayed
- Payment failure if USDC balance is insufficient for the $0.02 per-call fee
- 502/503 if the x402-factory aggregation service is temporarily unavailable
