## How to call it through Zero

zero fetch --capability forwardlane-repository-quality-tiers-e1c4ef75
```

Example prompt: Show me how ForwardLane groups repositories by quality tier and how many repos are in each tier.

## When to prefer this

Use this endpoint when you need a high-level summary or distribution of repository quality tiers before drilling into individual repositories, rankings, or detailed snapshots. It is the lightest and most aggregated view available — prefer it over the rankings or repository list endpoints when you only need tier labels and counts.

## Known failure modes

- No tiers available if the dataset is empty or not yet indexed
- Network or payment failure returning 402 if USDC payment is not properly attached
- Unexpected server error (5xx) if the tier computation pipeline is unavailable

## How this service works

Repositories grouped by quality tier with counts.

## Output

A list of quality tiers, each with a tier name/label and a count of how many repositories belong to that tier. Enables understanding of the overall quality distribution across the indexed repository dataset.
