## How to call it through Zero

```

Example prompt: What's the passer rating for a quarterback who had 32 attempts, 24 completions, 312 yards, 3 touchdowns, and 1 interception? Show me the component scores too.

## When to prefer this

Use this endpoint whenever you need the official NFL passer rating formula applied to raw passing stats. It is purpose-built for American football QB evaluation, returns all four intermediate components (not just the final number), and flags perfect and degraded results. Prefer it over general math or sports data APIs when you need the official 0–158.3 scale rating with transparent component breakdown.

## Known failure modes

- Missing required query parameters (attempts, completions, yards, touchdowns, or interceptions) returns an error
- Attempts value of 0 causes division-by-zero, likely returning null rating
- Non-integer values for numeric fields may be rejected
- Completions exceeding attempts produces an out-of-bounds component, may return degraded flag or error
- Very large or negative values may return a clamped or null rating

## How this service works

NFL passer rating (0 to 158.3) from attempts, completions, yards, touchdowns and interceptions, with each component.

## Output

Returns the computed NFL passer rating (0–158.3 scale), each of the four component values (completion rate, yards-per-attempt, touchdown rate, interception rate), overall completion percentage, yards per attempt, a summary verdict, and flags indicating whether the rating is perfect (158.3) or degraded. May include disclaimer notes and reasons.
