Infermedica

Verified Jul 2026

Infermedica's Engine and Platform APIs take structured or free-text patient evidence (symptoms, risk factors, demographics) and return probable conditions, triage urgency, and specialist recommendations, authenticated with paired App-Id/App-Key headers issued on signup to the free Developer Portal. Building and testing an integration is free via a Dev-Mode sandbox; taking it to production requires a commercial contract, so pricing is freemium rather than fully paid. The old /docs/ URL now 301-redirects to /documentation/, corrected in place. A live Origin-header probe against api.infermedica.com returns Access-Control-Allow-Origin: *.
