Market Data API for AI Agents in 2026
Finance questions become safer when a tool distinguishes three jobs: identify the instrument, retrieve its latest available snapshot, and return a defined historical range.
Quick answer
Resolve the symbol, then request quote and bounded history.
Use stock search for a company name, market data for a reliable symbol, and market movers for daily equity rankings. Request an output currency in the same call when a chat UI needs a converted price and chart.

- Chart-ready MCP Apps
AI-ready output
Markdown for models. JSON for systems.
Raw HTML consumes tokens on navigation, scripts, styling, and interface labels. Clean Markdown keeps the readable hierarchy for LLM prompts and RAG chunks. Normalized JSON is better when your application needs an explicit semantic type, source, author, publication date, media, attributes, and collection items.
Always retain the canonical URL from the response. AI-generated summaries should remain traceable to the public source, especially when the underlying page can change.
Boundaries
Public data only
- Data may be delayed.
- Prices are not investment advice.
- Trading, portfolio history, and arbitrary intervals are out of scope.
