Complete API reference
What is the Kantesti Blood Test API?
The Kantesti Blood Test API, also used as a lab test API and lab test AI API, is a REST API for AI blood test analysis. Send a laboratory test report as a PDF or image and the blood test AI extracts every biomarker (CBC, lipid panel, liver and kidney function, thyroid, vitamins, hormones and more), compares each value against reference ranges and returns a structured JSON report with plain-language interpretations, a health score and disease-risk indicators.
Developers use the blood test API to build patient apps, telehealth platforms, laboratory portals and clinical decision-support tools. Authentication uses simple credentials, responses are localized in 100+ languages, and a free sandbox lets you test the AI blood test API without consuming credits.
This blood test API documentation covers authentication, every endpoint (blood test analysis, trend analysis, nutrition diet AI, blood test comparison, ICR document extraction and family health risk assessment), error codes and rate limits, with code examples in cURL, Python and JavaScript.
The same endpoints accept laboratory test reports from any lab, in any layout, as PDF, JPG or PNG.
