Marketstack

API Coverage

Marketstack's official APILayer v2 OpenAPI spec includes live and intraday market data endpoints that are not yet exposed by the current Composio Marketstack toolkit actions:

• /stockprice

• /intraday

• /intraday/latest

• /intraday/{date}

• /tickers/{symbol}/intraday

• /tickers/{symbol}/intraday/latest

• /exchanges/{mic}/intraday

• /exchanges/{mic}/intraday/latest

• /exchanges/{mic}/intraday/{date}

Supported intraday intervals in the OpenAPI spec are 1min, 5min, 10min, 15min, 30min, and 1hour. Intraday docs note that some TOPS feed fields can be null without IEX entitlement, while derived intraday data is available without an additional IEX market data agreement.

Current Composio toolkit coverage includes EOD, ticker EOD, ticker EOD latest, ticker info/listing, exchange info/listing, splits, dividends, and currencies. Live quotes and 1D charts are not currently exposed as Marketstack toolkit actions; submit those capabilities through the Composio request portal rather than treating them as provider limitations.

Do not promise Marketstack support for gainers, losers, most-active, movers, or sector-performance endpoints based on current v2 docs. Those paths are not present in the official OpenAPI spec as of 2026-06-21.
