What is Claw Arbs?

Claw Arbs is a standalone desktop application for automated arbitrage and value betting. Unlike scanner tools that identify opportunities for you to act on manually, Claw Arbs detects and executes bets autonomously — finding the spread between two venues and placing both legs within milliseconds of an edge opening.

The bot is built around a direct-connection philosophy: instead of relying on third-party odds feeds that scrape bookmaker pages, process the data, and relay it with 500–2000ms of additional latency, Claw Arbs connects directly to venue APIs via WebSocket and sits on bookmaker pages with a headless browser using MutationObserver to detect DOM changes in ~20ms. By the time a third-party service updates, the trade is typically already placed.

The app ships with 10 pre-integrated venues and a community calibration marketplace that lets you add any publicly accessible sportsbook. SportsGameOdds serves as the external sharp reference feed for the value betting engine, providing the 11-book aggregated true-odds line that drives edge calculations.

The 10 Pre-Installed Venues

Claw Arbs ships with working integrations for all ten venues:

Venue	Connection Type	Speed	Notes
Kalshi	WebSocket	~25ms	US prediction market; no account limits
Polymarket	WebSocket	~25ms	Crypto prediction market; global
Predict.fun	API (P2P)	Fast	Prediction market; no account limits
SX Bet	API (P2P)	Fast	Decentralized; no account limits
Sportmarket	Headless browser	~20ms	Mollybet broker; sharp Asian market access
Stake.com	REST API	Fast	Crypto sportsbook (USDT, BTC, ETH funding)
BC.Game	Headless browser	~20ms	Crypto sportsbook
Cloudbet	REST API	Fast	Crypto sportsbook
Pinnacle (PS3838)	REST API	Fast	Sharp reference and execution venue
BetInAsia	Headless browser	~20ms	Broker access to Asian books

The pre-installed venues are the strongest combination for cross-venue arbitrage: prediction markets (Kalshi, Polymarket) against sharp traditional sportsbooks (Pinnacle, Sportmarket) produce the largest and most durable spreads because they price different fundamentals.

Strategy Agents: The Control Layer

Strategy Agents are the core configuration primitive in Claw Arbs. Each Agent is an independent execution engine with its own parameters:

• Sport and market filters: specify exactly which sports and bet types each Agent trades
• Edge thresholds: minimum and maximum edge percentage before execution
• Reference venues: which sharp books to use as the true-probability benchmark
• Target venue: where to place the bet (or “Auto” for the book with best available odds)
• Execution mode: paper (log only) or live (execute)
• Bet sizing: fixed dollar amount, percentage of bankroll, or Kelly-based
• Per-event and daily limits: maximum exposure per match, maximum daily drawdown

You can run dozens of Strategy Agents in parallel. A soccer arbitrage agent targeting Kalshi vs. Sportmarket has nothing to do with a Polymarket vs. Pinnacle cross-venue politics arb agent. They run independently with separate risk limits.

This granularity is the key difference between Claw Arbs and simpler bots. Rather than one global configuration that applies to all trades, you define strategy-specific logic that reflects how you actually think about each market type’s risk profile.

SportsGameOdds Integration: The Sharp Reference Feed

For value betting specifically, Claw Arbs integrates with SportsGameOdds as an external sharp odds reference. The integration works as follows:

Your SportsGameOdds API key connects to their odds endpoint, returning current lines from 40–82 bookmakers depending on your plan. Claw Arbs feeds these into its internal 11-book sharp aggregator, which calculates a blended true-odds line by weighting Pinnacle, BetISN, Pin88, and other sharp books together and stripping vig.

This synthetic sharp line becomes the reference for value betting agents: if a soft bookmaker’s odds are better than the true probability implied by the aggregated sharp line, a value bet exists. The Claw Arbs engine fires the target venue, logs the edge, and tracks CLV at close.

Which SportsGameOdds plan you need:

Plan	Cost	Update Frequency	Recommendation
Rookie	$99/month	3 minutes	Minimum viable — works for pre-match value betting
Pro	$299/month	Sub-minute	Recommended for live in-play and active arbitrage

The 3-minute update interval on Rookie is sufficient for pre-match value betting where lines move slowly. For live in-play arbitrage where edges open and close in seconds, the Pro plan’s sub-minute updates are necessary to catch meaningful opportunities.

Adding bet105 and Other Sportsbooks

bet105 is not one of the 10 pre-installed venues but can be added through Claw Arbs’s calibration system:

1. Check the Community Hub inside the app — search “bet105”. Community members frequently share calibrations for well-known books.

2. If no community config exists, use the Calibrate feature: open a headless browser pointed at bet105’s odds page, identify the CSS selectors for odds values, and map them to Claw Arbs’s internal schema. The MutationObserver setup catches DOM changes in ~20ms once calibrated.

3. Verify with paper mode before going live — run the bet105 agent in paper mode for 24 hours to confirm the calibration is catching real odds and the bet sizing is correct.

This same process works for any publicly accessible sportsbook. The community marketplace has calibrations for Bet365, DraftKings, FanDuel, William Hill, and many more — typically within days of a new venue being requested.

The 14-Step Safety Pipeline

Every trade passes through Claw Arbs’s safety pipeline before execution. Key steps include:

1. Deduplication — reject trades already queued or recently executed for the same event/market
2. Naked leg protection — if the first leg of an arb executes but the second fails, halt execution and flag for manual review
3. Cooldowns — enforce a waiting period after a goal/red card/suspension event before firing on that match
4. Exposure limits — enforce per-match and per-day maximum exposure
5. Per-match rate limiting — prevent repeated firing on the same match within a window
6. Kill switch — one-click halt of all Strategy Agents; settles all open legs

These safety features address the most common ways automated arbing goes wrong: execution failures that leave naked legs, overexposure to single events, and rapid-fire execution during volatile match events.

Intelligence Layer: Weather, News, and AI

Beyond basic arbitrage, Claw Arbs includes an Intelligence Layer for value betting:

Sharp Odds Aggregator: Blends 11 books including Pinnacle, Pin88, BetISN, and BetDEX into a single true-odds line. Halts trades when sharps freeze a market (typically 5–15 seconds before soft books react to goals or red cards), preventing execution against stale lines.

Weather Signals: Stadium-level precipitation, wind speed, and temperature forecasts fed into value-bet strategies for outdoor soccer. Lines at soft books often lag weather model updates by 5–30 minutes — a meaningful edge window for outdoor over/under and BTTS markets.

News and Lineup Signals: Injury announcements, starting-XI confirmations, and manager decisions parsed in real time. A late lineup change can move a soccer moneyline 3–6% in 30 seconds with soft books lagging. The engine halts firing on stale lines and queues bets against venues that have not yet repriced.

Per-Market AI: Trained models per sport and market output probability estimates that update faster than any single bookmaker. On niche markets where Pinnacle is slow to update, the AI line serves as the freshest reference.

Live In-Play Arbitrage

Live in-play opportunities are the highest-margin trades in automated betting — edges of 3–8% are common during active matches when books disagree on probability following game events. Claw Arbs handles live arb with:

• Simultaneous monitoring of all connected venues during active events
• Sub-second reaction time to odds movements
• Auto-halt during high-volatility events (goals, red cards, injuries) via the sharp aggregator signal
• Goal cooldown enforcement — configurable wait period before re-enabling execution post-goal

Live arbing requires consistent machine uptime. A 30-second network outage during a high-volume match can mean missed opportunities or — worse — a naked leg if the first side executes before the connection drops. A dedicated machine or cloud server is strongly recommended for serious live arb operation.

Claw Arbs vs Manual Arbitrage Scanners

Dimension	Claw Arbs	Manual Scanners (BetBurger, RebelBetting)
Execution	Fully automated (~20ms)	Manual — you click the bet
Speed to market	~20ms from edge detection to placed bet	15–120 seconds (human execution)
Opportunities captured	High — executes faster than edges close	Lower — many edges close during manual placement
Setup complexity	Medium (15–60 min)	Low (SaaS, web-based)
Cost	Free (+ SportsGameOdds $99–$299/mo)	$79–$319/month
Execution risk	Minimal (automated safety pipeline)	Higher (human error on live arbs)
Account risk	Moderate (bot patterns can be detectable)	Lower (human betting patterns)
Best for	High-volume automated execution	Bettors who prefer manual control

The tradeoff is account risk. Automated bots place bets at consistent speeds with consistent patterns. Some sportsbooks detect and limit accounts showing bot-like behavior. The pre-installed venues (prediction markets, crypto books, sharp brokers) are specifically chosen because they either do not limit winning bettors or operate in decentralized environments where limiting is structurally impossible.

Verdict

Claw Arbs delivers genuinely impressive execution infrastructure at zero platform cost. The ~20ms execution speed is real and meaningful — by the time a third-party odds feed has relayed an edge to you, Claw Arbs has already placed the bet. The pre-installed venue selection covers the highest-value cross-venue arbitrage opportunities in 2026: prediction markets against sharp traditional books.

The alpha status is honest — expect occasional bugs and follow the Discord for update notes. The safety pipeline is comprehensive enough to handle the common failure modes of automated arbing. SportsGameOdds integration at the Rookie or Pro tier turns the bot into a capable value betting engine as well.

For bettors focused on prediction markets, crypto sportsbooks, and sharp brokers like Sportmarket and Pinnacle, Claw Arbs is the most capable free automated execution tool available today.

Recommended for: Serious arbers and value bettors targeting prediction markets and sharp/crypto venues who want fully automated execution at no platform cost.

Not recommended for: Bettors primarily targeting US-regulated soft sportsbooks (DraftKings, FanDuel, etc.) where automated bot patterns carry the highest account risk.
