# Upload a PDF file to a knowledge base

`POST /knowledgebase/{id}/items/upload-media`

Upload a PDF file to a knowledge base. Only PDF files are accepted (validated by MIME type and extension).

**400 is returned for billing/entitlement failures before the file is processed:**
- `"Insufficient credits for KB storage upload."` — account lacks upload credits
- `"KB storage access is not enabled for your account."` — plan doesn't include KB storage

No application-level file size limit is enforced — any proxy or infrastructure limits (e.g. nginx) apply instead.

Knowledge base item created successfully

  - `status` boolean

## Other responses
