Verdicts

OpenCage Geocoding API

Permanent storage of results on every plan, including after you cancel. Geocoding only, no place search or routing.

Stadia Maps

Public OpenAPI spec (11.1.0) with generated TypeScript and Python SDKs. Free plan is for development, testing and demos only.

Before you call either

OpenCage Geocoding API

  1. Add no_annotations=1 and limit=1 when you only need coordinates
  2. Stop on 402, which means the day's quota is gone, and back off on 429
  3. Add no_record=1 when the query holds personal data
  4. Redact the key parameter before logging request URLs
  5. Credit OpenStreetMap wherever you show results

Stadia Maps

  1. Send the key as Authorization: Stadia-Auth <key> rather than in the URL
  2. Try Autocomplete v2 (1 credit) before a full geocode (20 credits) when a name is enough
  3. Check the dashboard's credit balance before retrying a 429, since it may mean the month is spent
  4. Don't write geocodes to a database on Free or Starter
  5. Use bulk-geocode for addresses only, not POI names
