Field notes
The route example compares a direct trip from the Saint Louis Art Museum to Soulard with a calmer alternative, showing distance, duration, and busy-road exposure. The API response is described as including elevation at route points and named street details for sidewalks and crosswalks; the page also says build metadata helps determine when a cached route remains valid.
