missing_api_key

No API key in the request.

HTTP status	401
code	missing_api_key
Retry?	No, fix the request first

What it means

The request has no Authorization: Bearer … header, or the header is not of the form Bearer <key>. An unknown path under /v1 also answers with this error instead of 404 when no key is sent, so the API does not reveal which paths exist.

How to fix it

Send the key as Authorization: Bearer ks_live_… or ks_test_…. Check that no proxy or HTTP client strips the header. You create keys under Settings › Developer / API.
