Copy-ready prompts

Use these as starting points with an agent. Each one names the live site and the API source to check.

Reference

Availability API

Use this when you need court names, locations, slot counts, and available times.

GET
/api/courts?sport=tennis&city=sf

Court availability by sport and city.

GET
/api/health

Simple service health check.

Travel API

Use this when a user gives coordinates and wants to compare travel time.

GET
/api/directions

Walking and driving estimates for up to 50 locations.

Use safely

Good behavior

The data is public, but it is still live availability. Keep answers grounded in what the API returns.

  • Report unavailable live data instead of guessing.
  • Prefer the API contract over scraping the client UI.
  • Include source URLs in summaries so results can be verified.
