Welcome to the Nomics Cryptocurrency & Bitcoin API. To sign up for an API key please go here.
nomics.com is built entirely with the Nomics API. Everything we've done on nomics.com you can do with our API. There are no internal API endpoints.
If you need support, reach out to use at our forums.
The Nomics API runs at https://api.nomics.com/v1. All requests should be prefixed
by the server URL.
By default, all endpoints serve data as JSON. However, by passing format=csv in the URL,
some endpoints will return CSV data. This can be used in Google Sheets via the IMPORTDATA
function.
CSV responses will not contain a header row, this is so that data can be easily concatenated from multiple requests. The fields will be rendered in the same order as the JSON fields. See the endpoint's documentation for an example.
Not all endpoints support CSV. Endpoints that support CSV will have the format parameter in
the parameters section.
The Nomics API uses standard HTTP status codes to indicate success or failure. 200 represents success, 4xx represents a user error (such as a problem with your key), and 5xx represents a problem with our API.
We follow Semantic Versioning. That means our API is versioned as Major.Minor.Patch. For example, Version 1.2.3 has major version 1, minor version 2, and patch version 3.
Major version changes indicate that we have altered the API significantly and it is no longer compatible with a previous version. Major versions are also used as the API URL prefix.
When we update the major version, we will not remove the previous version without notice to API customers and a deprecation period to allow everyone to smoothly update to the new version.
Minor version changes indicate that we have added new functionality without breaking any existing functionality. An API client is compatible with future minor versions. Note that a minor version update may add a new field to an existing API endpoint's response. Your API client must ignore fields it does not understand in order to be compatible with future minor versions.
Patch version changes indicate we fixed a bug or security vulnerability. Patch versions don't add new functionality.
This API supports Cross Origin Resource Sharing, which allows you to make API requests directly from your user's browser.
To use CORS, you must provide Nomics with the domains on which your application will run so that we can whitelist them for CORS access.
Requests from localhost, 127.0.0.1, and 0.0.0.0 will always succeed to aid in development.
A demo application using the Nomics API, CORS, and React is available on Glitch.com. This can help you get started using the Nomics API. Keep in mind it uses the demo key, which is rotated frequently. You should get your own API key before deploying an app to production. Check it out:
Here is a demo of using the Nomics API with Google Sheets.
=IMPORTDATA("https://api.nomics.com/v1/prices?key=your-key-here&format=csv")=LOOKUP(D2,A:A,B:B) finds D2 (BTC) in column A and pulls the price from column B=E2*F2=G2/I$2=SUM(G:G)We love watching developers explore new use-cases with our API. Whether you're tinkering on a small side project or building an open-source resource, please share what you're up to in our forums.
You must include your API Key as a query parameter in every request you make.
For example:
