Preview brief
# Integration brief: STRATZ

Goal: build a feature on STRATZ data. Use only the official documentation below as the source of truth.

## Known facts (from SportDex, verify before relying on them)
- Website: https://stratz.com
- Docs: https://stratz.com/api
- Sports: Esports
- Data: Historical data, Player stats, Team stats
- Protocols: GraphQL; formats: json
- Auth: bearer
- Free plan: Free token
- Note: Docs site returned 403 to fetch; relied on homepage and search snippets. Rate limits unverified. STRATZ+ is a consumer subscription (not modeled).

## Verify before writing code
- live update frequency
- whether commercial use is allowed on the plan you pick
- exact endpoint paths, parameters and response fields (read the official docs, do not guess)

## Implementation rules
- Keep the API key on the server (environment variable, backend route or edge function); never ship it to the browser.
- Cache responses and respect rate limits; count how many requests each screen triggers.
- Handle errors explicitly: invalid key, quota exceeded (429), missing fields, empty fixtures, timeouts.
- Start with one demo request and log the raw response before building UI on assumed field names.
