Our review criteriaCatalog notes to consider when evaluating the integration, in addition to the provider documentation.
OpenCage's free tier is really a trial account, and the documentation is blunt about it: if you depend on the service regularly, you are not testing. Trial accounts are capped at 2,500 requests per day and one request per second. An API key is mandatory and passed as the key parameter on every request. A genuine advantage is that results may be stored permanently — there is no separate pricing for temporary versus permanent storage. Responses carry an attribution requirement. Anything going to production is expected to move off the trial onto a paid plan. Verified 2026-08-25.
