How this service works
Live probability: Who wins the next NBA Finals? — Stable evergreen URL for a recurring question: Who wins the next NBA Finals? 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 a consensus probability (0–1) for the NBA Finals winner, per-venue breakdowns from Kalshi and Polymarket (implied_p, 24h volume, liquidity score), divergence between venues, 1-hour probability move, resolution date, current market slug, and a rolls_to_next_at timestamp indicating when the evergreen URL will auto-forward to the next season's market.
Example use cases
Pre-game championship odds check
“What does the prediction market currently say about who's most likely to win the NBA Finals this year? I want the aggregated probability across all venues.”
Tracking odds shifts after a big trade
“A major trade just happened — can you pull the latest NBA Finals winner probabilities and tell me how much they've moved in the last hour?”
Comparing venue divergence on Finals odds
“Are Kalshi and Polymarket agreeing on NBA Finals winner odds right now, or is there a big divergence I could take advantage of?”
Technical details
Endpoint
GEThttps://x402-factory.com/v1/evergreen/nba-finals-winnerWhen to prefer
Use this endpoint when you need a stable, always-current URL for NBA Finals winner probability without tracking seasonal market slugs manually. It is ideal for recurring monitoring, dashboards, or agents that need the answer to 'who wins the next NBA Finals' without knowing the current market identifier. Prefer this over raw venue APIs when you want cross-venue aggregation (Kalshi + Polymarket) with divergence and liquidity scoring in a single call.
Side effects
- No active NBA Finals market exists (off-season gap before next market opens) — may return null or empty per_venue array
- Prediction market venues temporarily unavailable — missing per_venue entries for affected venue
- Market just resolved and roll-forward is in progress — brief window where current_slug may be stale
- HTTP 402 if payment header is missing or USDC balance is insufficient
- Stale data if upstream market feed is delayed
