Which sportsbook-odds API should I integrate?
Scoped narrowly: you need DraftKings/FanDuel/Bet365-style fixed-odds data rather than prediction-market pricing. (If it's actually Kalshi/Polymarket pricing you want, that's dino.markets, a different category entirely, covered in the FAQ below.) Here are seven real options, evaluated on credit model, latency, and pricing transparency, sourced from each provider's own site as of 2026-07-09.
Credit model is the first thing to budget
The Odds API meters by markets times regions per call instead of by request: three markets across two regions is 6 credits, and historical odds cost 10x that. 500 free credits a month sounds generous until a multi-market request burns through it in under 100 calls. SportMonks and OddsJam are simpler to forecast: flat per-plan access rather than a multiplier you have to model.
The Odds API
500 credits/mo free, ~40 mainstream sportsbooks (Bet365, DraftKings, FanDuel, William Hill), $30/mo for 20,000 credits on the entry paid tier. The most transparent pricing of anything on this list, and the one most referenced in developer discussions of this category. the-odds-api.com
SportMonks
Football-only, flat-rate: plans from €29/mo, a free plan for a first call, 140+ bookmakers across 42 market types via a Premium Odds Feed built with TXOdds, spanning 2,500+ leagues. Simplest credit model on this list, at the cost of being single-sport. sportmonks.com
OddsBlaze
The latency tier to reach for if sub-second updates actually matter to your integration: WebSocket streaming from $249/mo. REST-only access starts at $29/mo. No free tier, and you need a card on file before you see anything. oddsblaze.com
OpticOdds
The other sub-second option: 200+ sportsbooks, odds under 800ms, integration documented at under 5 minutes per their own guide. No public pricing at all; budget for a sales cycle before you get a number. opticodds.com
OddsJam
100+ sportsbooks with player props, futures, and live in-play markets, plus a full historical feed for backtesting. Built for traders and syndicates at scale, and priced accordingly: no published number, sales-gated. oddsjam.com
SportsGameOdds
Pre-match and live odds aimed at both developers and sportsbook operators. Less documented pricing transparency than The Odds API, but comes up almost as often in the same developer discussions. sportsgameodds.com
Sportradar
The integration to reach for only if you need official league-rights data specifically: NBA, NHL, MLB, NFL partnerships. Not sized for an indie integration: no public pricing, third-party estimates put contracts at $30K+/mo, unconfirmed directly by Sportradar. developer.sportradar.com
The decision tree, condensed
Need the most transparent, cheapest entry point: The Odds API. Football-only and want flat pricing: SportMonks. Need sub-second updates for a bot: OddsBlaze or OpticOdds, budget accordingly. Need official league-rights data: Sportradar, budget a lot more. Need a consumer-facing +EV/arb tool alongside the raw API: OddsJam. None of these are the right integration if what you actually need is Kalshi/Polymarket pricing; that's a different category.
Common questions
What's the actual integration decision here?
Credit model and latency tier. The Odds API's markets-times-regions credit math is the main gotcha to budget for; a flat-rate API like SportMonks is easier to forecast cost on. If you need sub-second updates for a betting bot, only OddsBlaze and OpticOdds deliver that; everything else is REST-poll speed.
Why isn't dino.markets in this list?
It's a prediction-market API rather than a sportsbook-odds API. It doesn't cover a single traditional sportsbook. If your integration actually needs Kalshi/Polymarket pricing rather than sportsbook lines, that's the tool; see the companion Reddit-flavored piece for more on the distinction.
