Measured tools (11)

• create_meter

  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.

  Parameters:

  • provider (required) — string
  • consumer (required) — string
  • unit (required) — string
  • price_minor_per_unit (required) — number
  • currency — string
  • sla_target — number

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• record_usage

  Record a usage event. Idempotent on event_id (safe to retry — never double-billed). outcome is 'ok' or 'error' and feeds the SLA report.

  Parameters:

  • meter_id (required) — string
  • event_id (required) — string
  • quantity (required) — number
  • outcome — string
  • metadata

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• usage_summary

  Totals for a meter: event count, total quantity, accrued minor units.

  Parameters:

  • meter_id (required) — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• sla_report

  Pure SLA report: success_rate vs sla_target, breach flag. No mutation.

  Parameters:

  • meter_id (required) — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• close_period

  Freeze all open events into an immutable invoice (exactly-once). The invoice amount is what agent-escrow-agent should settle.

  Parameters:

  • meter_id (required) — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• verify_chain

  Verify the tamper-evident event hash chain for a meter.

  Parameters:

  • meter_id (required) — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_meters

  List all meters with event/invoice counts.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_events

  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.

  Parameters:

  • limit — integer
  • since
  • until
  • cursor
  • channel
  • outcome
  • meter_id
  • provider
  • include_test — boolean
  • consumer_class

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• usage_timeseries

  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.

  Parameters:

  • since
  • until
  • bucket — string
  • channel
  • meter_id
  • provider
  • include_test — boolean
  • consumer_class

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• flag_meter

  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.

  Parameters:

  • meter_id (required) — string
  • is_test (required) — boolean
  • admin_token (required) — string
  • note — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• describe_agent

  Fleet-standard self-description.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
