Why teams pick OHLC over Tiingo
- More than two developers need the data. Tiingo's Commercial plan covers internal use by up to two developers. OHLC's Pro plan covers internal business use for your team.
- You want fundamentals and filings included. OHLC's statements, metrics, dividends, splits, earnings and SEC filings come with every plan. Tiingo covers the Dow 30 and sells wider fundamentals as an add-on.
- You need more than end-of-day prices. OHLC also serves analyst ratings, estimates, ownership, insider trades, short interest, technical indicators and fund holdings on Pro and above.
- Backtests that survive ticker changes. Every listing has a stable
instrument_id, andas_ofandsymbol_atanswer what was known, and which company held a ticker, on any past date. Renamed, merged and reused symbols stop silently corrupting your history. - You pull many symbols at once.
/v1/eodtakes up to 100 symbols per request, and a whole-market day is one call withdate=. - You work with AI assistants. OHLC runs an official hosted MCP server, so Claude and other clients query the API directly.
When Tiingo is the better pick
Choose Tiingo if you mainly need long end-of-day history on a small budget (back to 1962 on its $30 Power plan), real-time IEX prices, IEX intraday from 2017, or Chinese A-shares, or low-cost end-of-day redistribution from $250 a month for startups.
Switching from Tiingo to OHLC
Both APIs take YYYY-MM-DD dates and return JSON or CSV, so the main changes are the path, the adjusted fields and auth.
- Daily bars.
/tiingo/daily/aapl/prices?startDate=…&endDate=…maps to/v1/eod?symbols=XNAS:AAPL&from=…&to=…(daily bars), with up to 100 symbols per request. - Adjusted fields. Tiingo returns raw and
adj*fields in the same row. OHLC returns one series per request: as traded by default, oradjustment=total_returnfor the equivalent ofadjClose. Methods can differ, so spot-check a few series after switching. - Dividends and splits. Tiingo's
divCashandsplitFactorcolumns become their own endpoints, /v1/dividends and /v1/splits. - Intraday and quotes.
/iex/{ticker}/prices?resampleFreq=5minmaps to/v1/intradaywithinterval=5m(intraday bars);/iex/{ticker}maps to/v1/quotes(quotes), delayed at least 15 minutes. - Auth. Replace
token=orAuthorization: Token …withAuthorization: Bearer $OHLC_API_KEY. See authentication. - Pagination. OHLC returns at most 500 rows per page. Pass
meta.next_cursorback ascursoruntil it is null. See pagination.
