# Vitals Vault OpenAPI Specification

Vitals Vault OpenAPI 3.0 specification for the public, keyless Educational Biomarker API.

## Machine-readable contract

The canonical JSON document is https://www.vitalsvault.com/openapi.json. It describes request parameters, response schemas, authentication requirements, rate-limit headers, and the versioning policy for the Educational Biomarker API.

## Execution model

Public Educational API operations are synchronous and return a final response in the same HTTP request. Follow the pagination parameters declared by each operation: the biomarker list supports cursor parameters in addition to page and pageSize, while category and lab-package lists declare page and pageSize. The biomarker batch request accepts at most 50 slugs. There is no public asynchronous job or polling endpoint.
