Tylee Smart Markets

The news terminal and all public information layers in Tylee Smart Markets are completely free to access without registration, account creation, or credential submission. Users can read live headlines from over 20 premium financial publishers including the Wall Street Journal, Financial Times, Bloomberg, Reuters, CNBC, MarketWatch, and Seeking Alpha. The Market Brief layer compresses 10 to 20 market-moving stories per trading day into plain-English summaries with rewritten headlines, source links, and market-angle labels covering rates, oil, equities, crypto, policy, and geopolitics. The Live Monitor surface shows real-time finance-impact signals including market TV, energy prices, conflict alerts, weather, earthquakes, and prediction market odds. System diagnostics and health status are also free and openly accessible. The only feature requiring payment is TTMA (Tylee Technical Market Analyzer) analytics, which makes external LLM API calls with real per-token costs - but even TTMA is free if users supply their own API credentials through the BYOK model.

BYOK stands for Bring Your Own Key. In Tylee Smart Markets, BYOK means users supply their own API credentials from preferred providers such as Groq, Google Gemini, OpenRouter, Finnhub, Alpha Vantage, Polygon, CoinMarketCap, and FRED. These credentials are stored encrypted in the user's browser local vault and never transmitted to TSM servers or any third-party service. When the user requests TTMA analysis or another premium feature, the credentials are forwarded directly to the provider the user selected, and only for that specific API call. This architecture has three concrete benefits: the user controls their credentials and can revoke them at any time, the user pays providers directly so there are no surprise charges from TSM, and analytics costs scale with the user's usage rather than being subsidized by the platform. BYOK is the reason the free tier on TSM can stay genuinely free without ads or subscription tiers.

Guest mode allows users to preview premium TTMA analytics features without providing their own API credentials. In guest mode, Tylee Smart Markets uses limited, cached, server-side API keys from providers that explicitly permit key-sharing with strong rate limits. When a user runs a TTMA query in guest mode, TSM forwards the request through its shared provider keys rather than the user's keys. Guest mode trades feature richness for accessibility: rate limits are tight because keys are shared across all guest users, there is no persistent storage of preferences or query history, and analysis depth may be limited compared to BYOK mode. Guest mode is useful for trying TTMA analytics before committing to obtaining your own credentials, for occasional users who do not need full capacity, or for users evaluating whether TSM fits their workflow. To unlock full TTMA capacity, users can add their own API keys at any time and switch from guest mode to BYOK mode in the same browser session.

Tylee Smart Markets separates features into free and BYOK tiers based on infrastructure cost and long-term sustainability. News aggregation and live monitoring are inexpensive to run at scale: they involve crawling public RSS feeds and aggregating headlines from over 20 publishers without expensive compute resources. These features stay free and open for everyone, including unauthenticated users and AI crawlers. AI-driven analytics such as TTMA, in contrast, require calling external LLM APIs (Groq, Google Gemini, OpenRouter, OpenAI, Anthropic) for each user request. These API calls have real per-token costs that scale linearly with usage. Rather than subsidizing those costs for all users (which would force TSM to introduce subscription tiers or advertising), TSM uses the BYOK model where users bring their own API keys and pay providers directly. This keeps the free tier genuinely free, removes per-user economics from the platform's cost structure, and lets premium analytics scale without raising prices for everyone or compromising on user privacy.
