Betting Broker API 2026: MadMarket, SportMarket & BetInAsia Guide
How to connect to betting broker APIs — MadMarket, SportMarket, AsiaConnect, and BetInAsia — for multi-venue execution at Pinnacle, Betfair, Asian books, and prediction markets through a single authenticated connection.
Betting broker APIs explained: multi-venue access through one connection
A betting broker sits between you and multiple underlying bookmakers or exchanges. Instead of managing separate accounts at Pinnacle, Betfair, SBO, and Kalshi, you fund a single broker account and route bets to any supported venue via the broker's unified API. The broker accepts professional bettors by design — no account limiting, no winning profiling, and large stake limits are standard.
For automated betting strategies, broker APIs unlock two key capabilities: (1) geographic access — if your jurisdiction blocks direct access to Pinnacle or Asian books, the broker provides access through their own licensed relationship; and (2) multi-venue execution — a single API call can route execution to the venue offering the best price at that moment.
MadMarket API: Pinnacle, Asian books, and Kalshi via one broker
MadMarket is a multi-venue sports betting broker with API access available to verified account holders. Its primary value is bridging two worlds that don't normally connect: traditional sharp sports betting (Pinnacle, Asian books) and prediction market betting (Kalshi) — all via one authenticated REST API.
- Venues covered: Pinnacle, selected Asian sharp books, Kalshi prediction markets
- API type: REST, JSON responses
- Access: KYC verification + minimum deposit + API access request
- Best for: Bettors in Pinnacle-restricted jurisdictions; strategies spanning both sports and prediction markets; Kalshi execution without a direct US Kalshi account
SportMarket API: Pinnacle, Betfair, and Polymarket access
SportMarket (sportmarket.com) is a Swiss-based broker focused on professional sports bettors. Their Pro tier provides API access to a unique combination of traditional sharp book (Pinnacle), traditional exchange (Betfair), and prediction market (Polymarket) — covering most of the execution venues relevant to a modern sharp betting operation.
- Venues covered: Pinnacle, Betfair Exchange, Polymarket, additional Asian books
- API type: REST, available at Pro tier
- Access: Full KYC, Pro account, minimum deposit (typically €10,000+)
- Best for: Strategies requiring Polymarket execution without direct crypto wallet management; bettors who want Pinnacle + Betfair + Polymarket from one account
AsiaConnect API: Asian handicap book access
AsiaConnect specialises in Asian handicap markets, providing programmatic access to Asian sharp books that are not directly accessible to most Western bettors. Their API gives access to Singbet, Crown, and other Asian operators offering tight margins on Asian handicap and full-time result markets across football, basketball, and major Asian sports.
- Venues covered: Singbet, Crown, and other Asian handicap operators
- Best for: Asian handicap strategies with high volume requirements; bettors who have exhausted soft-book liquidity and need access to sharp Asian pricing
- Access: Application and KYC required — contact AsiaConnect for current account terms
BetInAsia BLACK API: the highest-limit Asian broker
BetInAsia is a multi-tier broker with access to Asian sharp books via a tiered account system. API access is restricted to the BLACK tier — the highest level, designed for institutional-volume operators.
- Venues covered: SBO, Crown, Singbet, IBC/IBCBET, and other Asian operators
- Bet limits: Among the highest available — BLACK tier accounts can place very large individual bets
- Access: BLACK tier requires significant capital commitment; contact BetInAsia directly for current requirements
- Best for: High-volume sharp operators needing maximum Asian book coverage and stake limits

Wiring a broker API pipeline: step-by-step
-
Complete KYC and fund your broker account
Every betting broker requires identity verification (KYC) before API access. Prepare: government ID, proof of address, source of funds documentation. Deposit the minimum required amount. For MadMarket and SportMarket, minimum deposits are typically in the $1,000–$5,000 range. BetInAsia BLACK requires higher minimums — contact their team for current requirements.
-
Request API credentials
Broker APIs are not self-serve — after account verification, contact support or your account manager to request API access. You will receive an API key or OAuth credentials. Some brokers provide test environments (sandboxes); confirm whether your broker offers one before going live with real stakes.
-
Query available venues and markets
Use the broker's sports/markets endpoint to list available venues, sports, and current market prices. Broker APIs typically normalise odds across venues into a unified format — check the response schema to understand how venue identifiers, event IDs, and market types are labelled. Map these to your internal identifiers if you run cross-venue strategies.
-
Place bets via the broker's order endpoint
Submit bet requests specifying: venue, event ID, market type, side, stake, odds (or accept-best-available flag), and a unique request ID. The broker routes your bet to the target venue. The response includes: accepted odds (which may differ from requested if prices moved), bet reference ID, and status. Always store the broker's reference ID for subsequent status queries.
-
Monitor, settle, and reconcile
Poll the bet status endpoint to track open positions. At settlement, compare your P&L across venues to verify correct settlement. Most brokers settle automatically and reflect winnings in your broker wallet. Reconcile your broker statement against your own records weekly — discrepancies are rare but should be caught promptly.

| Maximum Asian book coverage | ✓ BetInAsia BLACK | Requires individual accounts |
Frequently asked questions
What is a sports betting broker and how is it different from a sportsbook?
A traditional sportsbook takes the opposite side of your bets (they profit when you lose). A betting broker routes your bets to multiple underlying venues — Pinnacle, Asian books, exchanges — and charges a small commission or spread. Brokers are designed for professional bettors: they accept large stakes, do not limit winning accounts, and provide API access that individual venues may not offer in your jurisdiction.
What venues does MadMarket provide access to?
MadMarket provides access to Pinnacle, a range of Asian sharp books, and Kalshi prediction markets. Their unified API allows betting across all these venues through a single authenticated connection. They are particularly valuable for bettors in jurisdictions where direct Pinnacle accounts are unavailable, or for strategies requiring simultaneous execution across multiple venues.
What venues does SportMarket provide access to?
SportMarket (sportmarket.com) is a Swiss-based broker providing access to Pinnacle, Betfair Exchange, and Polymarket, along with selected Asian books. Their Pro tier is required for API access. SportMarket is particularly useful for strategies that need both traditional sharp book execution (Pinnacle) and prediction market execution (Polymarket) via a single broker relationship.
What is BetInAsia BLACK?
BetInAsia is a multi-tier Asian book broker. The BLACK tier is their highest level, offering API access to Asian handicap books including SBO, Crown, Singbet, and IBC. BLACK requires significant capital commitment and is intended for high-volume professional operators. Standard and Pro tiers offer manual betting interfaces without API access. Contact BetInAsia directly for current BLACK tier requirements.
What is AsiaConnect and who is it for?
AsiaConnect is an Asian handicap specialist broker providing programmatic access to Asian sharp books (Singbet, Crown, and others). It is primarily used by bettors running Asian handicap strategies who want API access to sharp Asian prices without managing multiple individual Asian book accounts.
Do broker APIs add significant latency?
Broker APIs add 50–200ms overhead compared to direct book APIs. For pre-match betting, this is negligible — arb windows are measured in seconds to minutes. For live in-play betting, 200ms matters and direct APIs (if available) are preferable. If latency is critical to your strategy, confirm the broker's server locations and whether co-location options are available.
Can I use multiple brokers simultaneously?
Yes — many professional bettors maintain accounts with multiple brokers to access different venue combinations and increase execution capacity. MadMarket and SportMarket have different venue mixes, so using both in parallel can provide wider coverage. Manage per-broker capital allocation carefully; brokers hold your funds in their wallets.
