Same endpoints, same response shapes, same query parameters. 32 sources instead of 7. Real American odds on every line, not flat -115 placeholders. Polymarket and Kalshi integrated as sharp prediction-market signals. WebSocket streaming on Business+. Sub-300ms p95 on /odds with the full markets list. Migrate in one config change.
Apples-to-apples. Numbers are what we ship today; checkmarks are features either product offers; pricing is from each company's public pricing page (April 2026).
| Feature | ParlayAPI | the-odds-api |
|---|---|---|
| Sportsbooks (US) | DraftKings, FanDuel, Pinnacle, bet365, Caesars, BetMGM, BetRivers, Parx, Hard Rock, Fanatics, Bovada, Fliff, ProphetX, Novig (14 sharp + book sources) | 7 (DK, FD, BetMGM, Caesars, Bovada, plus 2 minor) |
| DFS pick'em | PrizePicks, Underdog, Sleeper, Betr, ParlayPlay, Pick6 (real American odds where available) | Limited or flat -115/-115 placeholders |
| Prediction markets | ✓ Polymarket + Kalshi | × Neither |
| Player prop markets | 14 books on player_strikeouts (MLB), 13 on player_points (NBA), all paired O/U on TOA-canonical keys | Available but fewer books per market, frequent flat-payout placeholders |
| Live scores | ✓ /v4/sports/{sport}/scores | ✓ |
| Historical odds | ✓ Up to 1 year on Enterprise | ✓ Bonus tier required |
| WebSocket streaming | ✓ /ws/odds/{sport}?apiKey= on Business+ | × Not offered |
| Update cadence | 2 to 3s verified freshness on Pinnacle and FanDuel hot leagues (beats their $99 Pro tier's 5s polling). Plus a Redis-backed verification heartbeat so the API can prove the price you see was confirmed within the last few seconds, not just last touched 30s ago. Sub-second push on WebSocket and SSE endpoints. | 30 to 60s polling, no streaming, no freshness verification |
| Freshness verification | ?include=verification adds verified_at, line_changed_at, and is_current per bookmaker so you can distinguish "price last moved 30s ago" from "we polled the book 2s ago and the price hasn't changed." Internal /admin/freshness alerts when any hot source drifts past 3s. |
One last_update field with no way to tell if it's stale or just unchanged |
| Response size on /odds | ~3 KB gzipped for a typical MLB h2h query (11.8x smaller than the raw 38 KB). All text responses gzip-encoded by default. | Uncompressed unless you set Accept-Encoding manually and their CDN happens to honor it. |
| API shape | Identical to TOA. Same paths, same JSON shape, same query params. | Original |
| Endpoint paths | /v4/sports/{sport}/odds (and /v1 alias) | /v4/sports/{sport}/odds |
| p95 latency on /odds (full markets) | 225ms | typically 300-800ms |
| Free tier | 1,000 credits/month, no credit card required | 500 credits/month |
| Affiliate program | ✓ 30% of first 12 months | × |
| Pricing (Enterprise) | $100/mo, 5M credits ($0.020 per 1K credits) | $1,499/mo, 30M credits ($0.050 per 1K credits, 2.5x more per credit) |
We undercut TOA at every tier on small and mid-volume plans. The honest math
on Enterprise: our $100/mo for 5M credits is $0.020 per 1K credits versus their
$1,499/mo for 30M ($0.050 per 1K). That's 2.5x cheaper per credit and roughly
15x less in total monthly spend, since you also get 6x fewer credits. If you
genuinely need 30M+/month, see our Scale tier ($200/mo for 50M, which works out
to $0.004 per 1K credits and beats every TOA tier on the per-credit comparison).
Programmatic pricing comparison: GET /pricing.
ParlayAPI mirrors TOA's REST shape exactly. Switch the base URL, you're done. Same paths, same response JSON, same query parameters.
