Smarkets Betting Exchange Scraper - Odds, Volume & Results

Exchange odds from Smarkets, the UK betting exchange, for football, tennis, US sports, horse and greyhound racing, golf, cricket, darts, politics and more:

• Back and lay odds with the stake available at each price (an order-book ladder), the last traded price and the matched volume of every market.
• Results: finished events with the score and which selection won, lost or was voided, plus the last traded price.
• Traded-price history: price candles per selection from before the start to the final whistle, with the last pre-play price (the exchange's closing odds), first traded, highest and lowest odds and the stake traded.

Exchange prices are the sharpest public odds there are: no bookmaker margin, real money on both sides. Use them as a benchmark against sportsbook lines, to measure closing-line value, or to track political and entertainment markets.

⚖️ Strengths and limits

Read this before you run a big job, so you know exactly what you get.

Strengths

• Real exchange prices. Back and lay odds with the stake available, last traded price and matched volume, from Smarkets' own public API.
• Closing prices and price charts. priceHistory gives the last pre-play price and traded-price candles.
• Wide coverage. 26 sports and categories, including politics and entertainment.
• Light. A default run takes a few seconds; no login, no proxy needed.

Limits

• Only about 10 days of history. Smarkets drops finished events after about 10 days, so results and priceHistory can't go further back. For a longer archive, schedule your own runs.
• Snapshots, not a live stream. Each run shows prices at that moment. There's no stored order-book history: priceHistory holds traded prices only, and only candles with trades.
• Candle size isn't your choice. Smarkets returns about 480 candles per request, so a longer window means longer candles.
• No incremental mode. Every run returns everything in scope. To track changes, compare runs on external_id and scraped_at yourself.
• Thin markets have gaps. Lower leagues and far-off outrights often show one side only, or no price at all, and available stakes can be small. This is one exchange's liquidity, not the whole market.
• One row per selection, so rows add up. Every upcoming football match, main markets only, was about 30,000 rows (about $60 at $2 per 1,000 on the free plan). Results for all sports passed 361,000 rows in a 30-minute test (over $700). markets: all multiplies this: about 80 markets per football match. Use sports, dates and Max results.
• Speed is limited by Smarkets. 60 requests per minute per IP: that football run took about 8 minutes, or about 4 with Apify Proxy.
• GBP only. Stakes and volumes are in pounds, odds are decimal.
• Results come oldest first, because Smarkets only sorts that way, so a capped results run gives the oldest events in your window.
• Read-only. It doesn't place bets.
• It depends on Smarkets' public API. If that changes, the actor stops working until it's updated. Not affiliated with Smarkets.

What you get

One row per selection of each market. Every row carries the event (event_name, competition, sport, start_time, event_state, event_url, venue), the live or final score where there is one (home_score, away_score, match_period, scores) and the market (market_name, market_type, market_volume_gbp).

entityType: "markets" (prices, the default)

Field	Example
event_name, competition, market_name	RC Lens vs Sporting, UEFA Champions League, Full-time result
contract_name, contract_type	Lens, HOME
back_odds, back_probability, back_stake_available_gbp	5.6, 17.86, 112.79
lay_odds, lay_probability, lay_stake_available_gbp	5.8, 17.24, 71.81
back_depth, lay_depth	[{"odds": 5.6, "probability": 17.86, "stake_gbp": 112.79}, {"odds": 5.4, ...}]
last_traded_odds, last_traded_at	5.6, 2026-10-13T17:51:07Z
market_volume_gbp	74927

Back odds are what you get backing a selection (the best price on offer); lay odds are what you pay laying it. Stake is the backer's stake in GBP available at the best price. Standing orders at the price limits (odds 1.0001 and 10000), which many markets carry, are left out.

entityType: "results"

Finished events with outcome per selection (winner, loser, voided), the final score and score breakdown (halves, periods, sets, extra time), actual start and end times, the last traded price and the market volume.

entityType: "priceHistory"

Field	Example
event_name, contract_name, outcome	Liverpool vs Man City, Man City, winner
first_traded_odds, preplay_last_odds, last_traded_odds	2.36, 2.1, 1.0
highest_odds, lowest_odds	3.15, 1.0
total_trades, traded_back_stake_gbp	1975, 145004.49
history_from, history_to, bucket_seconds	48 hours before kick-off, the final whistle, 180
candles	[{"time": "2026-10-09T15:57:00Z", "open_odds": 3.05, "high_odds": 3.05, "low_odds": 3.05, "close_odds": 3.05, "close_probability": 32.79, "trades": 1, "back_stake_gbp": 0.74}, ...]

Candle length follows the window: Smarkets returns about 480 candles per request, so a 48-hour window plus the match gives candles of a few minutes. Only candles with trades are included.

Good to know

• Finished events are kept for about 10 days. After that Smarkets no longer serves them, so results and priceHistory cover the last ~10 days. Schedule a daily run to build your own archive.
• Speed. Smarkets allows 60 requests per minute per IP, and one request covers up to 100 markets. Every upcoming football match on Smarkets (about 1,000 events, 30,000 rows of main markets) takes about 8 minutes without a proxy and about 4 minutes with Apify Proxy on 6 sessions; each proxy session gets its own budget.
• Prices are in GBP, the exchange's currency. Odds are decimal; probabilities are in percent.
• Football has about 80 markets per match and an NFL game more than 100 with player props, so markets: all gives many rows per event.
• No login needed, and no proxy needed except to go faster.

FAQ

What is the difference between back and lay odds? Backing is betting that a selection wins, at the best odds someone is offering. Laying is betting against it. The gap between the two is the exchange's spread.

Why is back_odds empty for some selections? No one is offering a price on that side right now. Thin markets (lower leagues, far-off outrights) often have one side only.

What is preplay_last_odds? The last traded price before the scheduled start, i.e. the exchange's closing price. Comparing it with the odds you bet at gives your closing-line value.

Can I get older results? Only what Smarkets still lists (about 10 days). Older events return nothing.
