ValueRay
Stock and ETF research data with peer rankings and market regime, served by REST API and MCP so AI assistants can analyze symbols.
What is ValueRay?
ValueRay is a screening and financial-analysis service covering US stocks and ETFs that also publishes its research as structured data for AI tools. A REST API returns JSON for a given symbol that covers price action, trends, support and resistance levels, risk metrics, performance, peer percentiles and dividends, along with sector rotation and the service's own proprietary signals. Other endpoints search symbols by name, ticker or ISIN, compare a stock with its closest GICS sub-industry peers on performance, valuation, profitability, debt and risk, and report the current market regime with sector rotation and breadth. An MCP server with OAuth connects ChatGPT, Claude or other agents, so the assistant fetches the data and writes the analysis. Authentication uses a Bearer token created in your profile. Free access is available, with upgrades for deeper research and higher limits, though no plan prices are shown.
Use cases
- Give an AI assistant stock research data
- Compare a stock with its peers
- Check the market regime before a trade idea
- Verify an investment claim with data
- Screen stocks and ETFs
- Resolve company names to tickers
