Base URL

The Nomos API is built on REST principles. We enforce HTTPS in every request to improve data security, integrity, and privacy. The API does not support HTTP.

All requests contain the following base URL:

  https://api.nomos.energy

Authentication

To authenticate you need to add an Authorization header with the contents of the header being Bearer nom_123456789 where nom_123456789 is your API Key.

Authorization: Bearer nom_123456789

Response codes

Nomos uses standard HTTP codes to indicate the success or failure of your requests.

In general, 2xx HTTP codes correspond to success, 4xx codes are for user-related failures, and 5xx codes are for infrastructure issues.

StatusDescription
200Successful request.
4xxClient error, see Error Codes.
5xxIndicates an error with Nomos servers.

Rate limit

The response headers describe your current rate limit following every request in conformance with the IETF standard:

Header nameDescription
ratelimit-limitMaximum number of requests allowed within a window.
ratelimit-remainingHow many requests you have left within the current window.
ratelimit-resetHow many seconds until the limits are reset.
retry-afterHow many seconds you should wait before making a follow-up request.

The maximum number of requests that users can send is 10 requests per second.

After that, you’ll hit the rate limit and receive a 429 response error code.

To prevent this, we recommend reducing the rate at which you request the API. This can be done by introducing a queue mechanism or reducing the number of concurrent requests per second. If you have specific requirements, contact support to request a rate increase.
