API & Developer Portal

Power your international admissions with the GradeAtlas conversion API. Reliable, standardized, and verified grading logic for every country.

Self-Service Keys Coming Soon

We are currently in private beta. Direct API access will be available shortly.

Integration Guidelines

Standardized Mapping

All API responses use ISO country codes and normalized 0-100 scales to ensure consistency across different source systems.

Rate Limiting

Standard tier permits up to 1,000 requests per month. Enterprise tiers offer unlimited scaling for high-volume admissions periods.

Data Freshness

Our grading database is audited monthly. All API requests include a 'last_verified' timestamp for transparency.
