Get Usage
GET/v1/usage
Return today's UTC quota usage per endpoint bucket.
Does not consume any rate-limit bucket. A single pass over the
7 Valkey keys is issued via ZCARD (returns 0 for missing keys).
Limits are resolved against the effective tier returned by
core.tier.get_api_key_tier — the same 3-value set
("free" / "paid" / "internal") that check_rate_limit
uses to enforce per-request caps. The human-facing auth.tier
label (from the api_keys.tier column) is preserved in the
response's tier field for display. When the two disagree, a
usage.tier_drift warning is emitted so production monitoring
can detect billing-webhook/admin-tooling skew.
