• What happens when you exceed the quota: blocked or billed

• Whether live and historical data are on your plan

• Whether your use (public app, betting, resale) is licensed

Preview brief

# Integration brief: ParlayAPI

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

## Known facts (from SportDex, verify before relying on them)
- Website: https://parlay-api.com/docs
- Docs: https://parlay-api.com/docs
- Sports: Multi-sport (40+)
- Data: Historical data, Odds, Play-by-play, Player props, Live scores
- Protocols: REST, WebSocket, SSE; formats: json
- Auth: api_key
- Free plan: Free, 1000 requests per month
- Cheapest paid plan: $5/mo
- Note: Pricing via WebFetch of /pricing (docs page showed 'See plans'). Annual prepay offered. Self-serve plans are for internal use; redistribution needs a separate agreement.

## Verify before writing code
- live update frequency
- 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.
