## 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 cannastack-strain-finder-f780a246 -d '<json body>'
```

Example prompt: Can you find dispensaries near Denver, CO that carry Blue Dream flower and tell me where I can get it cheapest right now?

## When to prefer this

Use this endpoint when an agent needs to find real-time cannabis strain availability and pricing across multiple dispensaries in a US city or region. It is purpose-built for cannabis retail discovery — combining geospatial dispensary lookup with menu scraping and price comparison in a single call — making it far more efficient than scraping individual dispensary websites. Prefer it over general web search when you need structured, comparable pricing data across dispensaries rather than unstructured results.

## Known failure modes

- No dispensaries found near the specified location
- Strain not currently in stock at any nearby dispensary
- Invalid or unresolvable location string
- Network or upstream data source unavailable
- Payment failure via x402 protocol preventing call execution

## How this service works

Agent-native cannabis data. Dispensary menus, prices, deals, and strain availability across the US, priced like an API call via x402.

## Output

Returns a JSON object with a list of matched dispensaries including name, address, rating, review count, and URL; each dispensary lists the matched strain with its price, brand, category, genetics type, and whether it can be ordered. Also includes a human-readable summary (e.g. '12 matches at 8 dispensaries, cheapest $28 at Native Roots'), resolved location coordinates, response time, number of dispensaries searched, and suggested next API actions like fetching 30-day price history for the strain.
