  description: The API requires a key. An unauthenticated GET to a documented endpoint returns HTTP 401 with the body
    {"error":"API key missing"}. The docs do not say which header or query parameter carries the key.
  evidence:
    observed_status: 401
    observed_body: '{"error":"API key missing"}'
    observed_on: '2026-10-28'
  portal_claims:
  - 'Secure JWT'
  - Authenticated user onboarding with profile validation and controlled key-based API consumption.
summary:
  credential: API key issued after registering on the IMD API Management portal (https://api.imd.gov.in/public/register.php)
    and logging in. The PDF API document says organisations should contact the nodal officer and must follow IMD's terms and conditions.
  note: The portal homepage mentions JWT, but the public API reference (api_reference.html) does not document the auth header,
    the token format or how to obtain a JWT. Login and registration endpoints were not called.
