Ship in four steps

  1. 1Design rubric & prompts — align pedagogy (or domain rules) with model instructions.
  2. 2Test OCR & grading — validate on representative sheets in the playground.
  3. 3Annotate visuals — bound boxes and structure flow into perception downstream.
  4. 4Expose with RBAC — who can author, publish, and call the endpoint.

Sample · invoke /v1/math-grade

curl -X POST https://api.dex28.io/v1/math-grade \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: multipart/form-data" \
  -F "guided=@answer_key.pdf" \
  -F "submission=@student_scan.jpg" \
  -F "rubric_profile=ed-std-2025"

Use the same flow for chatbots, enterprise search, or field inspection — one platform, many endpoints.
