# NFL Pairing Rank – Head-to-Head Form Comparison

> NFL Pairing Rank – Head-to-Head Form Comparison is a paid API for AI agents from nfl-form-x402.owenlvll.workers.dev, paid per call via x402, $0.4/call, status unknown (last checked 2026-09-14).

Returns percentile-ranked form metrics for both teams in a specific NFL matchup (home vs. away) for a given season and week, enabling direct head-to-head comparison.

## 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 nfl-pairing-rank-head-to-head-form-comparison-fc5bb2a0
```

Example prompt: Pull the pairing rank comparison for the 2024 NFL regular season, week 9 matchup between Arizona (home) and Chicago (away) — I want to see both teams' percentile-ranked form stats side by side.

## When to prefer this

Choose this endpoint when you need a side-by-side percentile comparison of two specific NFL teams' form for a single game. It's ideal for matchup analysis, betting research, or fantasy football decisions where you want both teams' stats normalized and ranked in a single call rather than making two separate team-rank lookups and joining them yourself.

## Known failure modes

- Invalid or out-of-range season (outside 2016-2025) returns an error
- Invalid week number (e.g., week 0 or week 19 where not applicable) returns an error
- Unknown team abbreviation returns an error or empty result
- Payment failure via x402/USDC results in 402 Payment Required response
- Requesting a future week with no data yet may return null or empty stats

## How this service works

NFL team form aggregates 2016-2025, paid per request over x402 (USDC on Base). Free: index, sample, README, schema.

## Output

A JSON object with home_rank and away_rank sub-objects, each containing ~50 form metrics for that team entering the specified week: touchdown rates broken down by quarter and phase (offense/defense), passing and rushing yards per play, explosive play rates, sack rates, interception rates, fumble rates, red zone conversion rates, field goal situation percentiles, game-state distribution (percentage of snaps while leading/trailing/tied by margin), penalty counts, and both week-level and pooled percentile scores for each metric. Data covers the 2016–2025 regular seasons.
