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.

curl --get 'https://extractor.sh/api/extract' \

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.

extractor.sh does not bypass CAPTCHAs, login walls, paywalls, access controls, or regional restrictions. Review the source’s terms and applicable law before collecting or reusing data.
