Uploads

Docex uses presigned upload URLs to keep large files out of API request bodies. Your client uploads directly to storage, then references the upload ID when creating a run.

​

POST /v1/uploads/presign

​

SDK example

const docex = createDocex({ apiKey, baseUrl });

// The SDK handles presign + upload automatically:
const result = await docex.run({
  file: "./invoice.pdf",     // SDK reads file, presigns, uploads
  prompt: "Extract line items, totals, and vendor details",
});
