SLIPWATCH
Open the appA blown-out crane day sits in the forecast. A stalled permit sits in city records. A lumber squeeze sits in last month's price index. Slipwatch checks the free public sources every morning and hands you one ranked brief: what is likely to slip in the next 7 days, the evidence with numbers, and who has to act today.
Free public data only. No API keys, no signup, no database. Agents can buy a brief straight from the API: POST /api/risks is pay-per-call over x402, $0.02 USDC on Base.
This is the live brief for 2631 Kramer Ln, a real $48M podium build in Austin, rendered from today's data and refreshed hourly. Every card carries the evidence, the concrete next step, and the source it came from. A source that fails shows up as down, and a risk that is not there is not invented: when the project's building permits check clean, no permit card appears.

Every brief prints “N of M sources checked.” A source that is down is reported in the brief, never silently skipped.
Location, weather-exposed trades, materials on the buyout, permit numbers. Thirty seconds; the profile lives in your browser.
Forecast, permit records, price indexes, the calendar, and local news are queried fresh on every run. Each source fails alone; one dead API never blanks the brief.
Risks ordered by score. Highest severity first, each with why, the action, the owner, and the source.
Nothing to install and nothing to sign up for. The app opens on a real project pulled from the permit feeds: a $48M podium build on Kramer Ln in Austin, with a 46-story Chicago tower, a Seattle school addition, and a West 21st St building one click away. Swap in your own site's location, trades, and permit numbers and the next brief is yours. The profile stays in your browser.
