Dome API: Normalized API responses for markets, prices, books, history, wallets, orders, and matches.
Engineering required
Alphascope: No API integration required for the normal product workflow.
Dome API: Requires an API key, application code, storage, monitoring, and ongoing integration maintenance.
Execution responsibility
Alphascope: Does not place trades or hold venue credentials.
Dome API: Infrastructure can support trading integrations, but builders remain responsible for auth, controls, and venue execution logic.
What Dome API provides
Dome's official documentation describes a unified API for prediction-market data across Polymarket and Kalshi, including real-time prices, historical candlesticks, full order books, wallet analytics, order tracking, and cross-platform market matching.
The value is normalization. Native exchanges expose different identifiers, schemas, authentication, order-book formats, and lifecycle states. A unified layer can reduce the amount of venue-specific code a team must own.
Dome versus a finished research product
An API returns ingredients, not a complete decision. A team still needs storage, retries, symbol mapping, equivalent-contract logic, charts, alerting, news enrichment, forecasting, monitoring, and a user interface.
Alphascope bundles those research steps into an application. It is the better fit when the user wants to inspect a market now rather than build a product around raw responses. Dome is stronger when a developer needs control over the data model or wants to embed prediction data elsewhere.
Questions to ask before choosing Dome
Unified data does not make two contracts equivalent. Matching logic still needs to account for wording, time zone, cutoff, resolution source, outcome set, fee, and venue status.
- Which platforms and endpoint families are currently supported?
- What are the freshness, retention, pagination, and rate-limit guarantees?
- How are corrected trades, cancelled markets, and resolution changes handled?
- Does cross-platform matching expose confidence and contract differences?
- What monitoring and fallback exists when a source API changes?
Dome API vs Alphascope FAQ
What is Dome API?
Dome is a unified prediction-market API providing normalized data from platforms including Polymarket and Kalshi for developers building analytics, bots, and other applications.
What data does Dome provide?
Dome documents real-time prices, historical candlesticks, order books, wallet analytics, order tracking, and cross-platform market matching. Confirm current endpoint coverage directly.
Is Dome API a replacement for Alphascope?
Not directly. Dome supplies programmable infrastructure, while Alphascope is a finished research interface. Dome requires engineering; Alphascope is designed for immediate human use.
Can Alphascope execute trades through Dome?
No. Alphascope does not expose a Dome-powered trading connection or place orders on a user's behalf.
Before you use this Dome API vs Alphascope guide
A good prediction market guide should help you make a more precise decision, not just explain the headline. Before trading, convert the market price into an implied probability, read the resolution criteria, and compare the contract with nearby markets. If your thesis depends on a news catalyst, check whether that catalyst directly affects settlement or only changes short-term sentiment.
The same checklist applies across Bitcoin, elections, sports, and other event contracts. A trade can look attractive because the payout is large, but payout alone does not create edge. Edge comes from a better probability estimate than the current price, plus enough liquidity to enter without giving away the advantage through spread and slippage.
Checklist for applying the guide to a live market
First, confirm that the market title and resolution source match the event you intend to trade. Second, compare the live price with your own estimate and write down the difference in percentage points. Third, check liquidity and maximum loss before sizing the position. Fourth, review related markets to see whether the same information has already been priced elsewhere. Fifth, decide what evidence would make you exit or update the thesis.
Alphascope supports that workflow through the odds board, AI predictions, and news impact pages. Use this guide as the educational layer, then use the live pages to check whether the current market still matches the setup described here.
How to know whether the setup is still current
A guide can explain the structure of a market, but the live price decides whether the setup is still actionable. Check when the market last moved, whether new information has arrived since the guide was written, and whether the strongest catalyst has already been priced in. If the market has moved far in the direction of the thesis, the remaining return may be too small for the risk.
If the market has not moved despite relevant news, review the resolution criteria before assuming traders missed the story. The market may be ignoring the news because it does not affect settlement. The best use of any guide is to understand the mechanics, then verify the current contract and price before making a decision.
