Assessment: Radar documents 36 REST operations in Markdown with a rate limit on each, and its status feed shows two short API incidents in 90 days. Access is sales-led. The pricing page says there is no free tier, every plan is an annual commitment, and no OpenAPI description or API changelog was found.

## Before you call it

1. Send the key in the `Authorization` header with no `Bearer` prefix, and call `https://api.radar.io/v1`, not radar.com
2. Use a publishable key for geocoding, search and routing. Keep the secret key for users, trips, geofences and beacons
3. Call `/v1/search/autocomplete` for partial addresses and place names. `/v1/geocode/forward` is documented as best for complete addresses
4. Set `units=metric` on routing calls. The default is imperial, with distances in feet
5. Treat 429 as one of three things (rate limit, no state change or selective throttling) and 402 as usage exceeded. No Retry-After header is documented
6. Do not keep geocoding, autocomplete or place results for more than 30 days

## Connect

```bash
npm install radar-sdk-js
```

```bash
curl "https://api.radar.io/v1/geocode/forward?query=20+jay+st+brooklyn+ny" -H "Authorization: $RADAR_PUBLISHABLE_KEY"
```
