BAKO API gives developers historical prices and machine-learning price predictions for stocks, ETFs, and cryptocurrencies through one simple REST API. Free to start — no API key needed to explore symbols.
Forecasts are statistical estimates based on historical data. They are not financial advice, and past accuracy does not guarantee future results.
Historical comparison between previous ML prediction runs and actual market close prices.
Most market data APIs return prices. BAKO API returns prices and forecasts — so you can build dashboards, screeners, research tools, and prototypes without wiring up a separate prediction model.
Daily close prices for every symbol, from first listing to today. Query any date range with a single request.
COVERAGE: 40,000+ symbols • Daily closes • Full history Forecasts generated daily by Vertex AI (TimesFM) and TensorFlow.js models, enhanced with real-time news analysis. Every prediction is scored against actual prices, and the accuracy is published daily.
MODELS: Vertex AI TimesFM • TensorFlow.js • News-enhanced • Daily scoring Three endpoints. Clear parameters. Copy-paste examples in cURL, Python, and JavaScript. No SDK to install, no complex auth flow.
ENDPOINTS: /v1/symbols • /v1/history • /v1/predictions Every prediction is compared against the actual price. We publish yesterday's accuracy, the 30-day average, and the all-time average — so you can judge the model on evidence, not marketing. Accuracy varies by market conditions; volatile periods are harder to predict. That is why we show the numbers instead of hiding them.
Benchmark & Methodology: Directional correctness is scored against market movements. Past accuracy reflects model performance under varying market volatility and does not guarantee future results.
Designed for fast integration into applications, analysis pipelines, and live investor tools.
Embed historical prices and 100-day forward forecasts directly into portfolio trackers and watchlist applications.
Combine decades of historical close data with model predictions to backtest ideas and screen market opportunities.
Access 6,700+ cryptocurrencies using the exact same clean REST endpoints as traditional equities.
Start immediately with our free tier offering 100 calls/day, zero credit card required, and keyless symbol search.
Simple, transparent pricing with no hidden fees or per-call surcharges.
