LINEmd
Arbitrage API leg

The arb scanner for the BettorsACE intelligence stack.

LineMD turns the platform's odds, arbitrage, steam-move, and alerting logic into a developer SaaS: REST endpoints, live streams, webhooks, usage controls, and clean handoff into the BettorsACE War Room.

Operational flow

Built around arbitrage detection, not generic odds browsing.

BettorsACE already consumes arb signals for premium pick logic and War Room alerts. LineMD packages that capability as a dedicated API product for builders, quant teams, and partner integrations.

01

Ingest the board

Normalize live prices across books, markets, sports, and event IDs before any opportunity is scored.

02

Detect negative hold

Calculate combined implied probability, stake split, profit margin, stale-book risk, and market completeness.

03

Verify and route

Send high-confidence windows to REST, SSE, webhooks, BettorsACE War Room, and social alert channels.

API surface

One arb API, multiple delivery modes.

Use REST for dashboards, SSE for live monitoring, and webhooks for alert workflows. The MCP layer remains underneath for agent-native access, while LineMD provides the simpler SaaS contract.
