What Can You Build with Free Odds APIs?
Understanding Free Tier Limitations
While free odds APIs are excellent for getting started, it's important to understand their limitations:
Request Limits
Most free tiers provide 100-500 requests per month. To put this in perspective:
- 500 requests/month = ~16 requests/day
- Checking odds for 10 games = 10 requests
- Updating every hour = 24 requests/day (exceeds daily limit)
- Solution: Cache data, update less frequently, or focus on fewer games
Feature Restrictions
Free tiers typically exclude:
- Player Props: Rarely available in free tiers
- Same Game Parlays (SGP): Usually paid-only
- Historical Data: Limited to recent games only
- Live Odds: May have delayed updates vs. paid tiers
- WebSocket Access: Often restricted to HTTP polling
Coverage Limitations
- Fewer sportsbooks (may only include 5-10 vs. 40+ in paid)
- Limited sports (major leagues only)
- No international bookmakers
- Missing alternative markets (Asian handicaps, etc.)
When to Upgrade to Paid
Consider upgrading when you:
- Exceed free tier request limits consistently
- Need player props or SGP data
- Require real-time updates via WebSocket
- Want comprehensive sportsbook coverage
- Need historical data for backtesting
- Launch to production users
- Require SLA guarantees and support
