## 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 ernte-halowerk-com-seasonal-profile-bad70f19 -d '<json body>'
```

Example prompt: What does the seasonal profile look like for apples in the German BLE wholesale market — broken down by share of quote observations across the year, keeping count and mass bases separate?

## When to prefer this

Use this endpoint when you need a normalized seasonal shape for a German agricultural product based on BLE wholesale quote frequency — particularly when you want to understand when a product is actively traded during the year. Prefer this over the raw weekly series endpoint when you need a relative distribution (shares) rather than absolute price or volume figures. Useful for planning, benchmarking, and dashboarding where the seasonal pattern matters more than the current price level.

## Known failure modes

- Product name too short (under 3 characters) or too long (over 60 characters) returns validation error
- Unknown or unrecognized product name may return empty or sparse profile
- Missing required 'product' field returns 400 bad request
- Payment failure via x402 protocol returns 402 Payment Required
- Seasonal data unavailable for niche products may yield incomplete profiles with many missing-observation flags

## How this service works

Seasonal profile as the share of German quote observations in the BLE wholesale report, not a market share. Example: product apples. Count and mass bases remain separate; missing current observations are explicit.

## Output

A seasonal profile object showing the distribution of BLE wholesale quote observations for the requested product across calendar weeks, expressed as shares of total annual observations. Count-based and mass-based observations are reported separately. Weeks with no current observations are explicitly flagged as missing rather than omitted.
