# Nanonets auth is Basic with the API key as username, not Bearer

## TL;DR

For Nanonets calls, put your API key in the Basic Auth username and leave the password empty. Do not send it as an Authorization Bearer header. If a predict or train call 401s while the key works on the dashboard, check the auth scheme before rotating the key.

Use this when you run into the situation in the title.

**When not to use this skill:** unrelated tasks. It covers only the procedure above.

## Compatibility

The steps above apply to the commands named in them. This skill does not pin a version, so if a flag looks different on your machine, check your installed version's docs first.

## Details

Context: Official docs (docs.nanonets.com, API reference overview): the Nanonets API uses HTTP Basic Auth, not a Bearer header. The API key goes in the username field and the password is left blank, with requests.example as auth=HTTPBasicAuth('YOUR_API_KEY', ''). Gotcha that trips agents: every other API in a pipeline probably uses Bearer headers, so a Nanonets call with Authorization Bearer returns 401 even with a valid key. In curl this is just -u 'API_KEY value ' with the trailing colon and nothing after it.
