Roadmap

MarketData would benefit from an official MCP server.

MCP is the open standard for connecting AI assistants to external tools, supported by Claude Desktop and Claude Code, Cursor, Windsurf and VS Code. A single server makes the API reachable from all of

Excel Add-in

Add an excel add-in to go along with the Google Sheets add-in.

Market holidays

Being able to retrieve an array of dates of upcoming market holidays would be helpful. I currently hardcode a table of holidays in my spreadsheet, but it would be nicer to populate it automatically. I

Request Log

Add a log of requests made to the customer dashboard.

Websocket Data

I believe Websocket Data could provide a huge beneficial use and reduce API calls. The industry standards for websocket have greatly improved and it'd provide a boost

Symbol lookup endpoint/formula

I tried for a few hours today to guess the correct symbol for NASDAQ with no success.

IV Rank & IV Percentile

Any plans to implement IV-Rank and Percentile?

Add 30d IV to Stocks & Indices

This would probably be a very attractive feature to many. If you decide it is warranted, perhaps add it to the live quotes too.

Stocks fundamental data

Add fundamental data for stocks

Historical Split/Dividends

Would like to be able to request history of splits/dividends for stocks.

Dividend History

I like what I see from the MarketData API in general, but it just falls a bit short of what I was looking for to migrate from Yahoo Pricing API requests to a commercial provider. The app I am maintain

Multiple option symbols in a single request

Allow API users to get multiple option contracts in a single request to avoid downloading quotes 1 by 1.

Implied Volatility

Add implied volatility data to options.

Options Greeks

Add C# (C-Sharp) SDK

Please provide an SDK for C# dotnet. Basically, supporting Dotnet Core with a single C# library, automatically provides support for C#, F#, VB.NET and other dotnet languages. Also see this related ite

endpoint for historical bulk daily!

full market in 1 call in specific date

API for credits used stats

It would be nice to be able to query the API to find out how many of the daily credits have been used. Something like: https://api.marketdata.app/v1/usage/?token=xxxx It would be helpful for tuning a

Mini SPX Options

is there support for mini SPX options data (ticker XSP)? thank you

Weekly vs Monthly options availability

It would be nice to have an end point that can provide information about options schedules. Some tickers have weekly options and some others have monthly. Currently I need to fetch the entire chain to

52 week high and low for a stock

It is possible to get a 52 week high and low for a stock? APPL return "164.075 - 260.10" for example

Improve Response Time

I LOVE the service (!!!!) but would love to see the response times of my requests improve.

Bug: make sure "x-api-" response headers are consistent in casing across endpoints

Rate limit response headers that are documented here https://www.marketdata.app/docs/api/rate-limiting#headers-to-manage-the-rate-limit Return with proper casing as documented on success and return as

Quote several option prices in one shot

I have option symbols in a column - say a couple dozen - and I need to query the option prices for each. Doing so with individual OPTIONDATA calls times out and generally works badly. If a single call

pre/post market Stockdata

real-time or delayed pre/post market Stockdata would be a big help if possible. and a big advantage over googlefinance.
