Efficient, Affordable, Customized: Our Success Stories

Our portfolio showcases a wide range of projects, each illustrating our commitment to efficient, affordable customization.

Verbose Stock Quotes
A client needed a verbose stock quote endpoint that also included additional details such as the (1) current daily candlestick and the (2) 52-week high and low. These detailed needed to be fetched in a single request, despite containing both quote data, trade data, and 1 year of historical data.
One Time Investment: $350
Option Chain Formula
A client requested an option chain formula for Google Sheets with extensive filtering options for both the strike (allowing filtering by strike price or delta) and dynamic expiration date filtering using DTE. The result not only pleased our client — the OPTIONCHAIN formula is now one of our most popular Google Sheets formulas.
One-Time Investment: $900
Option Symbol Lookup
A client needed to look-up the option symbol from his brokerage account’s CSV file. This file used a non-standard format and it wasn’t possible to get quotes using these symbols in Google Sheets. We not only added his broker’s custom format, we added all US retail broker CSV formats at no additional charge.
One-Time Investment: $350

How long does it typically take to develop a custom API endpoint?

Usually, it takes between 2 to 6 weeks to add a new project to our schedule, depending on the current project backlog. After your project has been added to our calendar, the actual development time will depend on the complexity of the requirements.

We typically divide large projects into 1-2 week milestones to allow for rapid delivery.

Most of our custom API endpoints come with a $50 per hour one-time development fee, with no ongoing fees other than a standard Market Data subscription. We would typically support your new endpoint as part of your Market Data subscription as well, meaning there are no ongoing fees for support or hosting either.

We collaborate with you to create an API that addresses your specific needs. From basic market data like stock quotes and options chains, to in-depth fundamental and technical analysis, we’ve got you covered. Our in-house experts in quantitative finance enable us to deliver advanced statistical analyses, time-series data, and other quant-specific metrics, all custom-built to align with your requirements.

Your Market Data token will give you secure access to your custom endpoint, the same way you access all other endpoints. Market Data takes responsibility for the security of for your endpoint.

Absolutely. Once we’ve developed your custom API, our commitment to you continues. Our team provides ongoing support at no additional monthly charge. If you encounter any issues, you can count on us for consistent and reliable service.

Definitely. We work with clients from around the globe. However, it’s important to note that our primary focus is on U.S. markets. If your custom API requirements involve sourcing data from foreign markets, the pricing structure may include a monthly charge instead of being a one-time fee.

Certainly. We offer flexible options for upgrading or modifying your custom API to meet your evolving needs. However, it’s important to note that upgrades or modifications are typically feasible as long as the changes introduced are non-breaking or optional for existing functionality.

While your data will remain private and secure, the API endpoint itself will be available to other Market Data users. By adding new APIs to our base product, we continually improve the service and are able to offer custom development at a much lower cost.

If the endpoint were exclusive to you, the hourly cost would be many times more expensive. We are not interested in taking on projects where the use of the endpoints must be exclusive to you or your organization.

No, our focus is solely on the financial markets.

While we do not offer custom front-end development, we can perform work to integrate our API endpoints into existing front-end charting libraries, frameworks, or interfaces.
