# Public Deadlines

## Request

- Base URL: `https://app.sentineliq.net`

Standard NWMLS deadline set from mutual acceptance.

Same builder as the keyed ``/agent-api/v1/deadlines`` and the
``nwmls_deadlines`` MCP tool (build_deadlines_response: every date from
add_business_days / add_calendar_days per RCW 1.16.050, never local
arithmetic), so the rows, disclaimers, and attributions are identical.
