## How to call it through Zero

```sh
zero fetch --capability api-crinkl-xyz-c50772eb
```

Example prompt: Using Crinkl verified purchase data, give me a campaign fit estimate for the 'personal-care' category in the Chicago metro area (CBSA 16980) over the last 14 days — and if you can, also score how well Target fits as a retailer for this campaign.

## When to prefer this

Use this endpoint when you need a quick, receipt-verified estimate of campaign viability for a specific product category — especially when you want to rank retailers or assess geographic fit using real consumer purchase signals. Prefer this over general market research tools when you need proof-backed, privacy-thresholded commerce data rather than survey or modeled estimates.

## Known failure modes

- Missing required 'category' query param returns 400 validation error
- Invalid or unsupported category slug returns empty or low-confidence estimate
- CBSA code not covered by Crinkl data returns no results or geo threshold error
- Days parameter outside 1-30 range returns 400 range validation error
- Payment not included or insufficient USDC results in 402 Payment Required
- Unknown merchant ID returns estimate without merchant-level scores

## How this service works

Get a campaign fit estimate from category demand and retailer activity.

## Output

Returns a campaign fit estimate object with category demand scores, retailer activity rankings, and geo-scoped signals derived from receipt-verified purchase data, indicating how suitable a given category and optional merchant are for campaign activation in the specified market and time window.
