From people using it

Notes from developers and operators who ship with these APIs.

Testimonial

I use the stock quote and the crypto quote in the same project. One key covers both, and I do not keep two accounts.

John D.John D. Senior Developer

Testimonial

I search AliExpress, then open a product for the price and the review totals. That replaced a spreadsheet I was updating by hand.

Sarah L.Sarah L. E-commerce Entrepreneur

Testimonial

The coin profile, the quote, and the holder list are the three calls I use. The catalog is paged, which is what a screener needs.

David S.David S. Crypto Enthusiast

Testimonial

I pull the schedule and the box score into a sports app. Baseball and hockey do not include betting lines.

Linda R.Linda R. Sports App Developer

Testimonial

I search listings, then read the tax history and the flood score for one address. I do not need those on every pin.

* Overage is optional and stays off until you turn it on in Billing. It is available on paid plans billed by card through Stripe, and not during a trial. Usage is counted in monthly periods that start on your billing day, yearly plans included. Requests past the included limit are charged at the plan's rate for each started block of 1,000, up to the overage cap, on one invoice after the period ends. Amounts under $0.50 carry over to the next invoice. If you change plans during a period, the limit and overage rate of the plan you are on when the period ends apply to the whole period.

The Free plan is also capped at 20 requests per day (New York time). Requests count by endpoint weight, and only responses with HTTP status 200 count.

Commercial use is included only on the plans that list it. If you are not sure whether your project counts as commercial use, email [email protected] before you launch.

Common questions

Short answers to what people ask first. The FAQ has more.

SteadyAPI is a set of REST APIs that return JSON data from stock markets, online stores, social platforms, travel sites, sports leagues, property listings, and more. One account and one API key work across all of them.
Any language that can send an HTTPS request. The documentation has samples in Shell, JavaScript, PHP, and Python for every endpoint.

Yes. For card subscriptions, upgrades and switches between monthly and yearly billing are charged right away, prorated for the rest of the period. Downgrades are credited on your next invoice, and moving to the Free plan happens at the end of the current period. You see the amount before you confirm. For other payment methods, contact support.
Create an account and confirm your email address. Choose a plan on the pricing page (the Free plan needs no payment), then create a key under Personal Access Tokens. Every endpoint in the documentation has a sample request you can run with your key.

Yes. Connect Claude Code, Cursor, VS Code, or another MCP client to https://api.steadyapi.com/mcp with your API key. Each tool call counts as a normal request by the endpoint's weight. Setup steps are on the AI agents page.

Paid plans do not include a trial at the moment. The Free plan lets you test the APIs, except options data, with 500 requests a month and no more than 15 requests a day.
