01 Developer Infrastructure & API

The accessibility API
for African platforms.

Integrate Limi into university LMSs (like myUnisa), EdTech platforms, and video courses with a single REST request or WebSocket stream.

Drop-In Transformation

One unified API contract for OCR layout analysis, indigenous translation, neural speech streaming, and 3D SASL kinematic plans.
