I've just started to use MarketData. I finished the first version of a Windows App that lets me gather and analize option chains and stock info.
So far so good. Servers have been up with no hiccups and my Application is running well with the API calls.
I would have given five stars but was disappointed that dividend data on stocks wasn't present. Dividend is a pretty standard metric. So I hope it is added soon.

Happy with Marketdata! Their team is super responsive and always there when I need help with data issues. They genuinely listen to feedback and keep adding cool new features. Plus, their prices are great for any account size. If you need reliable Stock and Options data, definitely give them a shot.
I use their live and historical Option Chain API for my algo trading, and it's become essential for my Options trading. They're quick to make updates and always keep me in the loop. Highly recommended.

I think it will meet my needs. Since it is a monthly subscription it is worth a try.

5 stars because the tool is very useful and integrates with GSheets nicely. Without this tool, trading options would be far more difficult for me. The only downside is I find it a bit clunky to use because it lacks any kind of autorefresh function and the data does not persist--it seems I frequently need to manually request a refresh and it is unclear to me what sort of time limits are at play. The data it serves up are not persistent in the sheet so a manual refresh is required unless I manually copy the data and save it with a call to paste special/values only. These are minor gripes about a very useful app.

We started using the Market Data (MD) OPTIONCHAIN formula to help speed up our quote time and delta calculations for our trading team. The amount of time we have saved by using this data has been extremely helpful to our team. We have opened several tickets since we first signed up for our annual subscription and the MD team has been very quick to respond to trouble tickets and to explain the features and limitations of the current MD solutions. We look forward to several of the new features that are currently under development on their company roadmap.

The service seems to work top notch. I was moving an existing app from another service and had very little friction doing the integration. I immediately went to ~1500 calls a day and have noticed no issues at all. I plan to integrate some additional functionality

Quotes are reliable and service is inexpensive. Option quotes via an API are hard to come by so that's a plus for this service. A few quirks here and there with the Google Sheets but my Python program is quite happy being able to get quotes without having to scrape an unreliable web page.

The quotation service has gone offline several times throughout the trading session, at critical moments. I hope it's a one-off problem.

Awesome support from people who understand both the technical development detail as well as the options market. Just what I was looking for - alternatives seem very antiquated and expensive, making the Market Data API the obvious choice with options data for backtesting strategies.

A simple and straightforward api. A very responsive support team. Great value for money. I look forward to using their services for a long time.
