Overview

Styvio provides real-time and historical stock price data combined with sentiment analysis based on social media and news signals. It is designed for developers who want to build trading tools, stock screeners, or market sentiment dashboards. An API key is required, and a free tier is available to explore its capabilities.

Beginner Tip

The sentiment score indicates whether the overall market mood for a stock is bullish or bearish based on recent news and social mentions. Combine it with price data to build more context-aware financial applications.

Common Errors & Troubleshooting

401 Unauthorized API key is missing or invalid.

✓ Pass your API key as the apikey query parameter or in the Authorization header as specified in the Styvio docs.

null sentiment value Sentiment data may not be available for low-coverage or non-US stocks.

✓ Check if the stock is in Styvio coverage list and handle null/undefined sentiment values gracefully in your code.

404 Not Found for ticker The stock symbol is not recognized or not supported.

✓ Use standard US stock ticker symbols (e.g., AAPL, MSFT, TSLA) and verify the symbol is listed on major US exchanges.

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
