Body

application/json

Text and schema for transformation

Request payload for transforming unstructured text into structured JSON

​
text
string
required

Unstructured text to transform

Example:

"Patient is a 45-year-old male presenting with chest pain..."

​
schema
object
required

JSON Schema defining the structure to extract from the text. Use description fields on properties to guide the model — they act as extraction instructions (e.g. "only include confirmed diagnoses, not suspected ones").

Example:
{
  "type": "object",
  "description": "Structured clinical summary extracted from a patient encounter note",
  "properties": {
    "patientInfo": {
