Marketstack

Marketstack provides real-time REST API for global stock market data across 70+ exchanges. Integrate market data analysis into applications.

Operational order

1. get exchanges — resolve MIC codes.
2. get tickers with mic (use INDX to browse index symbols such as DJI.INDX).
3. get ticker when you already know one symbol and need metadata.
4. get end of day with symbols — set latest=true for the newest bar; otherwise use date_from / date_to for history.
5. get dividends / get splits with the same symbols when corporate actions matter.
6. get intraday only when intraday bars are required — pick interval; plan limits apply.

Data Model

• Exchanges — MIC identifies venue; tickers are scoped per exchange.
• Indices — symbols end with .INDX (e.g. DJI.INDX); list via MIC INDX.
• End-of-day — comma-separated symbols (max 100 per call); pagination defaults to small pages.

Gotchas

• Symbol-scoped reads — end-of-day, dividends, splits, and intraday require symbols. Discover symbols via exchange tickers first when unsure.
• Intraday / real-time — upstream rejects or limits fine intervals on lower plans; use coarser interval values when errors mention plan or permission. Catalog smoke excludes intraday when the test API key plan does not include it; the tool remains for full-plan credentials.
• Pagination — default page size is small; increase limit only when needed (hard cap 100).
