Simple API Integration

Get started in minutes with our REST APIs. Works with any language.

// Create Knowledge Base
const formData = new FormData();
formData.append('name', 'Product Documentation');
formData.append('files', file);

const response = await fetch('https://backend.vgvishesh.com/knowledgebase', {
  method: 'POST',
  headers: { 'Authorization': `Bearer ${apiKey}` },
  body: formData
});

const { requestId } = await response.json();

Note: The API returns embeddings alongside text, giving you full flexibility to customize ranking and processing.
