API_KEY_MISSING

​

When it fires

​

Why it happens

• The request was sent without the header (most common on a first integration).
• A reverse proxy or HTTP client stripped the header.
• The wrong base URL. The documented endpoints live under /v1/*.

​

How to fix

GET /v1/portfolio HTTP/1.1
Host: api.kash.bot
X-API-Key: kash_live_<your-key-here>

• Send the key on every authenticated request. Keys are issued from the Kash web app (Settings → API Keys).
• The full key is shown once, at issuance. If you have lost it, revoke it and issue a new one.
