/kpi/metrics/sectors (not implemented)
Registered as a Financial Datasets-compatible route for parity, but not implemented by this deployment yet. Always answers HTTP 200 with a not_implemented ErrorResponse body, at zero cost and with no Monid call made — this is authenticated (X-API-KEY required) but otherwise free. See docs/compatibility.md for the phased implementation plan.
Authorizations
The caller's own Monid API key (get one at https://monid.ai?fpr=dhruv-15136b). Passed straight through to Monid on every call, so usage bills the caller's own wallet — this is never a shared server-side credential, and the server never logs or stores it. Missing, empty, or malformed values answer 401 unauthorized before any paid call is attempted.
Response
Zero-cost not_implemented stub.
Zero-cost stub body returned by every route in the "Not implemented" tag, always HTTP 200.
