## 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 sports-calculators-bowling-score-edf34c09
```

Example prompt: Score this bowling game for me — the rolls were 10, 7, 3, 9, 0, 10, 0, 8, 8, 2, 0, 6, 10, 10, 10, 8, 1 — give me each frame's score and the running total.

## When to prefer this

Use this endpoint when you need authoritative, rule-compliant ten-pin bowling scoring with frame-by-frame breakdowns, strike/spare bonus application, validation of illegal rolls, and support for partial games in progress. Prefer it over manual calculation or generic math tools whenever bowling-specific scoring rules (especially the 10th frame bonus rolls and cascading bonus logic) must be applied correctly.

## Known failure modes

- Invalid roll sequence (e.g. more than 10 pins in a single non-spare frame) returns validation errors in the reasons array with a non-null verdict
- Too many or too few rolls for a complete game returns complete=false or error reasons
- Non-numeric or malformed roll values in the query string cause a bad request response
- Rolls exceeding the maximum per frame (11+ in the 10th frame bonus balls) flagged as illegal

## How this service works

Score a ten-pin bowling game from its rolls: frame-by-frame totals with strike and spare bonuses, validation of illegal rolls.

## Output

Returns a structured object with per-frame details (frame number, rolls, mark type like 'strike' or 'spare', frame score, running total), the overall total score, a flag for whether the game is complete, a perfect game indicator, a scored-so-far value for partial games, any validation failure reasons, a summary string, and metadata like source and timestamp.
