## 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 bazaar-demand-forecaster-140375e7 -d '<json body>'
```

Example prompt: Using the last 90 days of aggregate demand events from our Bazaar marketplace data, forecast endpoint category demand for the next 60 days — I need confidence-bounded projections so I know which categories to prioritize for capacity planning.

## When to prefer this

Choose this endpoint when you need forward-looking, confidence-bounded demand forecasts specifically for Bazaar marketplace endpoint categories, using privacy-safe aggregate event data rather than raw user logs. Prefer this over generic time-series forecasting tools when the input is structured marketplace demand events and the output must be category-level with bounded evidence.

## Known failure modes

- Too few events (fewer than 1) triggers validation error
- historyDays or horizonDays outside allowed range (7–365 days / 1–365 days) returns 400
- events array exceeds 500-item limit
- Raw prompts or identities in events payload rejected for privacy reasons
- Service unavailable returns 5xx from Railway hosting
- Insufficient historical data may yield low-confidence forecasts

## How this service works

Forecast aggregate Bazaar demand by endpoint category with bounded evidence and confidence.

## Output

Returns a confidence-bounded demand forecast broken down by endpoint category, including projected demand levels, evidence strength, and forecast confidence intervals for the specified time horizon.
