Anyone who wants to process financial forecasts programmatically needs reliable time series. An isolated EPS estimate is enough neither for a valuation model nor for a screener or an AI agent.
Leeway's new Forecast API delivers exactly this structure: revenue, earnings, cash flow, EPS, and multiples. Quarterly and annually, for twelve quarters and three years into the future, for over 50,000 stocks worldwide. A single REST call returns a clean JSON object that can be processed directly.
Methodology
We look at patterns in quarterly and annual forecasts – revenue, net income, EPS, and the like – to see where the numbers are heading. It is a calculation of what has already been set in motion.
The process runs in three layers:
- AI interpretation: A model analyzes the company and the current outlook.
- Live sources: Current information flows continuously into the assessment.
- Algorithmic consistency check: A rule layer ensures that the metrics fit together mathematically.
Structure of the API response
The response is organized into the top-level objects quarterly and yearly. Both contain arrays of the respective metrics as date-value pairs. All derived figures reside in the ratios object of the respective period.
- Statement level: Revenue (
revenue), net income (netIncome), EBIT, EBITDA, free cash flow, operating cash flow, equity (stockholderEquity). - Ratios: EPS, book value per share (BVPS), revenue per share, cash flow per share, P/E, P/S, P/B, P/C.
Live example: SAP (testable without a token)
For a quick test, SAP.XETRA can be queried without an API token:
curl "https://api.leeway.tech/api/v1/public/fundamentals/forecast/SAP.XETRA"
The JSON schema stays identical for all 50,000 stocks, whether a DAX corporation or a smaller-cap name like Hornbach (GET .../forecast/HNR1.XETRA?apitoken=YOUR_TOKEN). Here is an excerpt of the structure:

FAQ
How are the forecasts produced? Through a three-layer process: AI-assisted interpretation, integration of live sources, and an algorithmic consistency check across all metrics.
Which metrics and which time horizon are covered? 12 quarters and 3 fiscal years for revenue, net income, EBIT, EBITDA, free cash flow, operating cash flow, and equity. Plus the ratios: EPS, BVPS, revenue/cash flow per share, as well as P/E, P/S, P/B, and P/C.
What is the difference between quarterly and yearly? The API returns two separate top-level objects with identical structure. Quarterly values do not have to be aggregated into annual values yourself.
How reliable are the forecasts? Forecasts are model-based estimates for informational purposes and do not constitute investment advice. Actual results may differ significantly.
