Web app gated by login; docs details come from a third-party directory (sportsapis.dev) and docs_url was not opened. Market Data API keys reportedly issued by email. Uncertain.
Before choosing a paid plan, confirm

• 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: ProphetX Goal: build a feature on ProphetX data. Use only the official documentation below as the source of truth. ## Known facts (from SportDex, verify before relying on them) - Website: https://www.prophetx.co - Docs: https://docs.prophetx.co - Sports: American football, Ice hockey, College sports, Football (soccer), Tennis, Golf, MMA, Esports, Basketball - Data: Trading & risk, Odds - Protocols: REST, WebSocket; formats: json - Auth: api_key - Free plan: none listed - Note: Web app gated by login; docs details come from a third-party directory (sportsapis.dev) and docs_url was not opened. Market Data API keys reportedly issued by email. Uncertain. ## Verify before writing code - pricing and request limits - 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.
