What this server can do
11 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
close_period(meter_id)- Freeze all open events into an immutable invoice (exactly-once). The invoice amount is what agent-escrow-agent should settle. Required: meter_id.
create_meter(unit, consumer, currency, provider, sla_target, price_minor_per_unit)- Create a usage meter between a provider and a consumer agent. unit: what is being counted (call, token, kwh, ...). Price is in minor currency units (cents) per unit. Returns the meter_id. Required: provider, consumer, unit, price_minor_per_unit.
describe_agent- Fleet-standard self-description.
flag_meter(note, is_test, meter_id, admin_token)- Admin: flag/unflag a meter as test/synthetic so its events are excluded from usage statistics by default. Touches meter metadata only — never events, never the hash chain, never billing accruals. Requires the server's VIRIDIS_ADMIN_TOKEN. Required: meter_id, is_test, admin_token.
list_events(limit, since, until, cursor, channel, outcome, meter_id, provider, include_test, consumer_class)- Read usage events (paginated, read-only). Filter by meter, provider, consumer_class (internal|external|unknown), channel, outcome (ok|error), and ISO date range [since, until). Test-flagged events are excluded unless include_test=true. Returns events + next_cursor.
list_meters- List all meters with event/invoice counts.
record_usage(outcome, event_id, metadata, meter_id, quantity)- Record a usage event. Idempotent on event_id (safe to retry — never double-billed). outcome is 'ok' or 'error' and feeds the SLA report. Required: meter_id, event_id, quantity.
sla_report(meter_id)- Pure SLA report: success_rate vs sla_target, breach flag. No mutation. Required: meter_id.
usage_summary(meter_id)- Totals for a meter: event count, total quantity, accrued minor units. Required: meter_id.
usage_timeseries(since, until, bucket, channel, meter_id, provider, include_test, consumer_class)- Usage time series bucketed on each event's recorded_at (UTC; bucket=day|hour), grouped across meters by provider — a real time-series primitive, independent of meter creation times. Includes per-bucket breakdowns by consumer_class / channel / provider. est_accrued_minor is an estimate; authoritative billing stays with usage_summary.
verify_chain(meter_id)- Verify the tamper-evident event hash chain for a meter. Required: meter_id.

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
