🔧 Postman Endpoint Fix

❌ The Problem

You're getting this error:

{
    "detail": [
        {
            "type": "missing",
            "loc": [
                "body",
                "file"
            ],
            "msg": "Field required",
            "input": null
        }
    ]
}

Cause: You're using the wrong endpoint!

🎯 The Solution

There are TWO different endpoints for image processing:

1. 📁 File Upload Endpoint (NOT what you want)

POST /transcribe-image
  • Expects: File upload (form-data)
  • Body Type: multipart/form-data
  • Use when: You have a local image file to upload

2. 🌐 URL Endpoint (What you NEED)

POST /transcribe-image-url
  • Expects: JSON with URL
  • Body Type: application/json
  • Use when: You have an image URL (like your iStock image)

✅ Correct Postman Setup

Method & URL

POST http://localhost:8000/transcribe-image-url

Headers

Content-Type: application/json
Accept: application/json

Body (Raw JSON)

{
  "url": "https://media.istockphoto.com/id/1468298683/pt/foto/mother-and-her-two-children-boy-and-girl-relaxing-in-nature-grass-field-watching-the-sunset.jpg?s=2048x2048&w=is&k=20&c=7wMm1zEerJCW3xDdm2gwovcdTBeU7DeayHEaYDNsJBI="
}

🔍 Step-by-Step Fix

  1. Check your URL bar in Postman

    • ❌ If it shows: http://localhost:8000/transcribe-image
    • ✅ Change it to: http://localhost:8000/transcribe-image-url

  2. Check your Body tab

    • ✅ Select "raw"
    • ✅ Select "JSON" from dropdown
    • ✅ Paste the JSON above

  3. Check Headers

    • ✅ Content-Type: application/json

📋 Visual Comparison

❌ Wrong Setup (File Upload)

POST /transcribe-image
Body: form-data
- Key: file
- Type: File
- Value: [upload file]

✅ Correct Setup (URL Processing)

POST /transcribe-image-url
Body: raw (JSON)
{
  "url": "your-image-url"
}

🧪 Test Both Endpoints

If you have a local image file:

POST /transcribe-image
Content-Type: multipart/form-data
Body: form-data with file upload

If you have an image URL (your case):

POST /transcribe-image-url
Content-Type: application/json
Body: {"url": "..."}

🎉 Expected Success Response

When you use the correct endpoint, you'll get:

{
  "file_id": "uuid",
  "file_info": {
    "name": "family_sunset.jpg",
    "extension": ".jpg",
    "size_mb": 0.34,
    "mime_type": "image/jpeg",
    "url": "your-image-url"
  },
  "success": true,
  "error": null,
  "title": "Family Enjoying a Sunny Day in a Field",
  "description": "Detailed description...",
  "extracted_text": "iStock Credit: kieferpix...",
  "processor_used": "OpenAI Vision",
  "processing_time": 6.4,
  "timestamp": "2025-09-23T14:19:52"
}

🔗 Quick Reference

Endpoint Use Case Body Type Content-Type
/transcribe-image Local file upload form-data multipart/form-data
/transcribe-image-url Image from URL JSON application/json

Your case: Use /transcribe-image-url with JSON body! 🎯
