## 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 api-crinkl-xyz-ccf71457
```

Example prompt: Pull the Crinkl category pulse for 'snacks' in the Chicago metro area (CBSA 16980) over the last 14 days — I want to see receipt-verified demand trends before we finalize our campaign targeting.

## When to prefer this

Use this endpoint when you need receipt-verified, ground-truth consumer demand signals for a specific product category — especially for CPG campaign planning, retailer fit analysis, or market sizing where self-reported or panel-based data is insufficient. Prefer over social-signal or survey-based trend tools when purchase evidence and geographic granularity (CBSA-level) are required.

## Known failure modes

- Invalid or unrecognized category slug returns an error or empty result
- CBSA code not available in Crinkl's coverage returns no data or an insufficient-activity error
- Days parameter outside 1–30 range returns a validation error
- Insufficient verified purchase volume for the requested geo/category combination may return no signal
- x402 payment failure or insufficient USDC balance prevents access

## How this service works

Get category demand trends from receipt-verified purchases.

## Output

Returns receipt-verified demand trend signals for the requested consumer category, including purchase activity metrics over the specified time window, scoped to the requested geography (national or CBSA-level). Data is privacy-thresholded and backed by verified shopper purchase evidence.
