How this service works
Daily construction delay brief built from free public signals: weather, city permit records, material price indexes, and the work calendar.
Output
A JSON object containing an array of risk items, each with a unique ID, date, severity level (high/medium/low), numerical risk score, human-readable title and explanation, recommended action, and data source. Also includes a list of data source statuses and a generation timestamp.
Example use cases
Pre-pour weather risk check
“I have a concrete pour scheduled for Thursday at my Chicago site at 41.8781, -87.6298 — can you check if rain or temperature will put it at risk and tell me what action to take if so? Also flag any permit issues under permit number BP-2024-9876.”
Weekly risk brief for active trades
“Give me a full delay risk summary for my Seattle framing and roofing project at 47.6062, -122.3321 — I need to know about lumber and plywood price risks and any weather threats this week so I can plan subcontractor schedules.”
Material and permit risk alert for NYC build
“My NYC construction project at 40.7128, -74.0060 is doing masonry and exterior-paint work this week. Pull a risk brief checking for concrete and gypsum material risks and any issues tied to permit 123456789 from the NYC portal.”
Technical details
Endpoint
POSThttps://slipwatch.vercel.app/api/risksWhen to prefer
Use this endpoint when you need a consolidated, actionable delay risk brief for a construction project site that combines weather, permit, and material signals in a single call. Prefer it over raw weather APIs when you need construction-trade-specific thresholds (e.g. concrete pour rain limits) and permit-correlated risk context. Best suited for daily briefing automation tied to a specific city portal-supported jurisdiction.
Side effects
- Unsupported city portal returns validation error — only Austin, Chicago, Seattle, NYC are supported
- Invalid or unrecognized permit numbers return no permit-related risks without error
- Missing lat/lon prevents weather forecast lookup
- Unavailable upstream data source (e.g. Open-Meteo outage) returns ok:false in sources array with degraded risk output
- Empty trades or materials arrays result in no trade- or material-specific risks
