Preview brief
# Integration brief: PropLine

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

## Known facts (from SportDex, verify before relying on them)
- Website: https://prop-line.com
- Docs: https://prop-line.com/docs
- Sports: Multi-sport (40+)
- Data: Historical data, Odds, Player props, Results, Live scores
- Protocols: REST, Webhooks, WebSocket; formats: json, csv
- Auth: api_key
- Free plan: Free, 1000 requests per day
- Cheapest paid plan: $9/mo
- Note: Young product (launched 2026). Annual billing gives 2 months free. Docs URL not stated in crawled text.

## Verify before writing code
- 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.
