## 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-opponent-strength-percentiles-for-one-game-7aebc2ba
```

Example prompt: What were the opponent strength percentiles for the 2023 season week 10 game where the Chiefs were at home against the Eagles — I want to see how each team's offense and defense ranked entering that game.

## When to prefer this

Use this endpoint when you need percentile-ranked opponent strength context for one specific NFL game — i.e., you know exactly which two teams played, which was home, and which week and season. It provides richer head-to-head context (44 attributes, both weekly and pooled percentiles) than a single-team rank endpoint, and is cheaper than pulling a full week or full season of pairings. Prefer this over the full-week or full-season endpoints when you only need one matchup.

## Known failure modes

- 404 if the two teams did not play each other as home/away in the given season and week — no charge is applied
- Invalid team abbreviation (not 2-3 alpha characters) causes schema validation failure
- Season or week outside 2016–2025 regular-season range may return no data
- Incorrect home/away assignment (swapped teams) returns 404 even if the teams met that week with reversed roles
- Network or worker timeout if the Cloudflare Worker is unavailable

## How this service works

Use when you need opponent strength for one NFL game in percentiles: both teams' /team-rank rows, 44 attributes each with a weekly percentile (vs the 32 teams that week) and a pooled percentile (vs every team-week 2016-2025), 1.0 best (two style measures left raw). Line up the home offense against the away defense: pass yards per play, 20+ yard passes, third down, red zone, touchdowns per drive. Form entering that week. 404, no charge, if the teams did not meet as home/away that week. JSON.

## Output

A JSON object containing two team-rank rows (one per team), each with 44 attributes. Every attribute carries a weekly percentile (how the team ranked vs all 32 teams that week) and a pooled percentile (ranked vs every team-week from 2016–2025), with 1.0 representing the best. Two style-measure attributes are returned as raw values. Returns HTTP 404 at no charge if the specified home/away pair did not meet in that week.
