Verdicts

Azure Maps

Azure Maps publishes OpenAPI documents for every service, per-service rate limits, a 99.9 per cent SLA and written rules on storing results, and Entra ID roles can limit a caller to one service. Place search exists only in Search 1.0, which the newer version has superseded, and the REST client libraries are all beta.

Radar

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 either

Azure Maps

  1. Send the key in the subscription-key header, or use Authorization: Bearer with x-ms-client-id. The key also works as a URL parameter, which leaks into logs.
  2. Call GET /geocode?api-version=2026-01-01 for addresses. It can return 200 with no results, so check confidence, matchCodes and the entity type before use.
  3. Use Search 1.0 (/search/poi/json, /search/nearby/json, /search/fuzzy/json) for places. The 2026-01-01 version has no place search.
  4. Use eu.atlas.microsoft.com or us.atlas.microsoft.com to keep request data in that geography.
  5. Don't store route or tile results beyond six months, and never for serving several users. The product terms allow keeping geocodes while the account is active.

Radar

  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
