Building an AU arb scanner, EV tool, or odds dashboard? Compare the four main Australian betting API providers — pricing, bookmaker coverage, latency, and developer experience.
Not every Australian bookmaker is useful for arbing, and not every one that is remains useful for long. The current state of the AU arbitrage betting landscape.
All three are household AU bookmakers. Their AFL pricing is genuinely different, and the differences matter if you're betting for value.
If you're building anything that touches Australian sports betting data — an arbitrage scanner, an EV tool, an odds dashboard, a data journalism project, or a research platform — you need reliable access to live odds from Australian bookmakers. The problem is that there are more options than there were a few years ago, and they differ significantly in what they actually deliver.
This piece compares the four main API providers covering the Australian betting market in 2026. We'll look at bookmaker coverage, pricing models, data depth, latency, and which use case each one handles best. The goal is to help you pick the right feed (or combination of feeds) for your project without wasting months on the wrong one.
Before comparing specific providers, it's worth being clear about what actually matters when choosing an AU betting API:
Krok Odds is the AU specialist. Where other APIs treat Australian bookmakers as one region within global coverage, Krok Odds is built entirely around the Australian market.
Coverage: 100+ Australian bookmakers. This includes the major corporates (Sportsbet, TAB, Bet365, Ladbrokes, Neds, PointsBet, Unibet, Betfair Exchange), mid-tier brands (BlueBet, BetRight, Dabble, Betr, TABtouch, Palmerbet), and over 80 white-label and smaller brands. No other API matches this depth for the AU market.
Sports: AFL, NRL, NBA, NFL, MLB, NHL, EPL, A-League, cricket, tennis, F1, UFC, golf, darts, plus AU racing (thoroughbred, harness, and greyhound). For racing specifically, Krok Odds also provides form data, speed maps, and sectional times.
Endpoints: Live odds, arbitrage opportunities, expected value calculations, middles, low-holds, player props, same-game multis, steam moves, predictions, webhooks, and historical archives.
Pricing: Free tier with 50 credits per month (5 requests per minute). API tier at A$49/month with 50,000 credits per month (500 requests per minute). Credits are weighted — standard odds requests cost 1 credit, archive requests cost 5, and bulk requests cost 25.
Unique features: Built-in fair-odds devig engine using Pinnacle as a sharp baseline. Pre-computed arbitrage and EV data so you don't have to calculate it yourself. SSE streaming for real-time updates.
Latency: Approximately 30-second polling cycle, with SSE streaming available for lower latency.
The Odds API is the established global player. It covers 80+ bookmakers worldwide across 40+ sports, with a large developer community and SDKs in multiple languages.
AU coverage: Around 15 Australian bookmakers, including Sportsbet, TAB, Bet365, Ladbrokes, Neds, PointsBet, Unibet, Betfair, Dabble, Betr, PlayUp, Palmerbet, BetRight, and TABtouch. Respectable for general odds access, but significantly shallower than Krok Odds for AU-specific use cases.
Endpoints: Odds, scores, fixtures, historical odds. Consensus-based EV calculations available at higher tiers. No pre-computed arbitrage data.
Pricing: Free tier at 500 requests per month. Starter at US$19/month, Pro at US$49/month, Business at US$99/month. Per-request pricing makes costs predictable.
Strengths: Best documentation in the space. Large community. SDKs for Python, JavaScript, Ruby, Go, and more. If your project needs global odds — or if you're building for an audience that bets across multiple countries — The Odds API is the natural choice.
Latency: Standard refresh is roughly hourly. Higher tiers get faster refresh rates, but it's still polling-based, not streaming.
Betfair Exchange API is fundamentally different from the other three. It's not an odds aggregation service — it's direct access to a single exchange. But for what it does, it's unmatched.
Coverage: Betfair Exchange only. Back and lay prices, market depth, and traded volume for sports and AU racing (thoroughbred, harness, greyhound).
Endpoints: Market data, price/volume history, account management, and full betting automation. The streaming API provides real-time price updates.
Pricing: Free API access. Revenue comes from commission on net winnings (5% standard, with volume discounts). No subscription fees.
Caveat: Requires a Betfair account and API application approval. The approval process is straightforward but it's not instant — plan for a few days of lead time.
Why it matters: Betfair is the only source of lay prices in Australian betting. If you're building an arb scanner, an exchange-leg tool, or anything involving market depth and traded volume, Betfair API is a required component regardless of what other API you use.
RapidOddsAPI is the newest entrant, appearing on Reddit in 2025 as an AU-focused alternative priced below the established players.
Coverage: Claims AU bookmaker coverage. The specific books and depth are less well-documented — developer claims on Reddit mention AFL, NRL, and NBA with spreads, totals, and player props.
Endpoints: REST and WebSocket APIs with standardised naming conventions.
Pricing: Reports suggest plans starting around US$49/month.
Transparency caveat: This is a smaller, newer operation with limited independent verification of its claims. The information above is based on developer posts and marketing materials. If you're considering RapidOddsAPI, we'd recommend testing it thoroughly against known odds from a few bookmakers before committing to it for a production project.

Krok Odds API — the best choice for AU-focused projects. If you're building an arbitrage scanner, EV tool, player prop analyzer, or anything that needs deep Australian bookmaker coverage, Krok Odds has no equal. The 100+ bookmaker coverage, built-in arb and EV calculations, and racing form data make it the most complete AU-specific option. The credit-based pricing model means you pay for what you use rather than a flat per-request rate.
The Odds API — the best choice for global coverage or multi-market projects. If your tool needs to work across Australian, European, and American bookmakers, The Odds API is the most practical option. The documentation is excellent, the community is large, and the per-request pricing is straightforward. The AU coverage is thinner than Krok Odds, but adequate for most general-purpose use cases.
Betfair Exchange API — the essential companion for exchange data. If your project involves back/lay comparisons, market depth analysis, steam-move detection against exchange prices, or trading automation, Betfair API is required. It's not a standalone odds feed — it only covers one exchange — but it's irreplaceable for what it provides. Most serious AU betting tools combine Betfair data with one of the other APIs.
RapidOddsAPI — worth investigating if you're budget-constrained and only need AU sports coverage. The pricing is competitive and the AU focus is appealing, but verify the claims independently before building on it. Newer providers can disappear, and limited documentation makes integration riskier.
Use Krok Odds API for the bookmaker leg (100+ AU books, pre-computed arb opportunities, player props) combined with Betfair Exchange API for the exchange leg. The pre-built arbitrage endpoint saves significant development time compared to computing arbs from raw odds.
Use The Odds API for breadth across 80+ global bookmakers, with Betfair Exchange API for exchange comparison. If your audience is international, The Odds API's multi-language SDKs and global coverage are strong advantages.
Start with either the Krok Odds free tier (50 credits/month) or The Odds API free tier (500 requests/month). Both are sufficient for prototyping and small-scale use. Upgrade when you've validated the project and know your actual usage patterns.
Use Krok Odds API for AU racing form data, speed maps, and sectional times — this racing-specific data isn't available from the other providers. Combine with Betfair Exchange API for exchange prices and market depth on race markets.
Use Krok Odds API for the widest player prop coverage across AU books. For global props, The Odds API covers player props at a subset of books. RapidOddsAPI also claims player prop data for AU sports, though independent verification is limited.
Understanding real costs requires looking beyond headline pricing:
Most production betting tools don't rely on a single data source. The pragmatic approach is to combine APIs based on their strengths:
This comparison was compiled from pricing pages, API documentation, community reports, and hands-on testing of all four providers as of August 2026. Pricing, bookmaker coverage, and features change — always verify current details on each provider's website before making a decision. Claims about RapidOddsAPI are based primarily on developer posts and marketing materials, as independent reviews are limited.
We run the Krok Odds API ourselves and have direct knowledge of its capabilities and pricing. Information about the other three providers is based on their public documentation and third-party reports. If you've found something inaccurate, let us know.
It depends on your use case. For AU-focused projects like arbitrage scanners, EV tools, or racing data platforms, the Krok Odds API offers the deepest Australian bookmaker coverage with 100+ books. For global multi-market projects, The Odds API has broader international coverage. For exchange data and trading automation, Betfair Exchange API is essential. There is no single best API — the right choice depends on whether you need AU depth, global breadth, or exchange functionality.
Entry costs range from free to around A$49/month depending on the provider. The Odds API offers a free tier with 500 requests per month and paid plans from US$19/month. Krok Odds has a free tier with 50 credits per month, with API access starting at A$49/month. Betfair Exchange API is free to access but charges commission (typically 5%) on net winnings. RapidOddsAPI reportedly starts around US$49/month.
Yes, though not all APIs surface arbitrage data directly. The Krok Odds API includes pre-calculated arbitrage opportunities, expected value calculations, and low-hold detection. The Odds API provides raw odds that you can use to build your own arb calculations. Betfair Exchange API provides the exchange leg for cross-market arbitrage. Most serious AU arbitrage operations combine multiple data sources.
Yes. Betfair Exchange API covers Australian thoroughbred, harness, and greyhound racing with real-time streaming, market depth, and traded volume data. The API also supports automated bet placement. You need a Betfair account and API application approval to access it.
The Krok Odds API covers 100+ Australian bookmakers including Sportsbet, TAB, Bet365, Ladbrokes, Neds, PointsBet, BlueBet, BetRight, TABtouch, Dabble, Betr, Unibet, Betfair Exchange, and over 80 white-label and smaller brands. This is the deepest AU bookmaker coverage available in a single API.
Yes. Both the Krok Odds API and The Odds API offer free tiers. Krok Odds provides 50 credits per month with 5 requests per minute. The Odds API offers 500 requests per month on its free plan. Betfair Exchange API access is also free, though commission applies to winnings. These free tiers are sufficient for prototyping and small-scale projects, though production use typically requires a paid plan.
