## 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-nfl-football-probability-movers-508f63b9
```

Example prompt: Show me the top 10 NFL prediction markets with the biggest probability swings in the last 6 hours — I want to see which outcomes are moving the most right now.

## When to prefer this

Choose this endpoint when you specifically need NFL football prediction market movers pre-filtered — it saves you filtering the generic /v1/movers endpoint yourself. Prefer this over the general movers endpoint when your agent or user is focused exclusively on NFL outcomes and you don't want noise from other categories like politics or crypto.

## Known failure modes

- Invalid window enum value returns 400 error
- limit out of range (>50 or <1) returns validation error
- min_liquidity outside 0–1 range returns validation error
- Payment not included or insufficient USDC returns 402 Payment Required
- No NFL markets with significant movement in the window returns empty movers array
- Service downtime returns 5xx error

## How this service works

Biggest NFL football probability moves (1h/6h/24h) — The fastest way to see where news is landing in NFL football: active markets ranked by absolute probability change over your chosen window, with volume surge ratios. Same shape as /v1/movers, pre-filtered to NFL football markets.

## Output

An array of NFL prediction market objects sorted by absolute probability change, each containing the market slug, question text, current probability (p_now), previous probability (p_prev), delta, volume surge ratio, and category — plus a meta object with request context. Up to 50 results depending on the limit parameter.
