Add Receipt OCR to Your Bolt.new App in 5 Minutes

The problem: AI builders don't read crumpled receipts

Tools like Bolt.new are remarkable at generating apps instantly — but they stop at the file boundary. You can build a beautiful expense upload interface in minutes, yet the actual extraction of merchant names, purchased items, taxes, and totals from faded thermal paper requires a dedicated Receipt OCR API. Most teams either skip this feature or spend days trying to force a general-purpose vision model to format line items correctly.

The solution: one API call, structured JSON

StructOCR's /v1/receipt endpoint accepts a photo and returns a clean JSON object with every field pre-labeled — no prompting, no parsing, no post-processing. Because it speaks plain HTTP, Bolt.new can wire it up from a single fetch call without heavy backend dependencies.

Integrate StructOCR in Bolt.new (3 Steps)

1. 1

   Create a Bolt.new project and describe your app

   Open bolt.new and start a new prompt. Describe the app you want to build — be specific about the receipt fields you need.

   💬Try this prompt: "Build a receipt scanner app. Users can upload a photo of a receipt and see the merchant name, date, time, and total amount extracted automatically."
2. 2

   Tell Bolt to call the StructOCR API

   Once Bolt scaffolds the UI, paste the follow-up prompt below. Bolt will write the fetch call, handle the file upload, and wire the response to your UI components in its in-browser editor.

   💬Follow-up prompt: "When a user uploads an image, send it as a multipart/form-data POST to https://api.structocr.com/v1/receipt with an Authorization header containing my API key. Display the returned JSON fields in the results panel."

   // Bolt generates something like this — you just supply the key in .env const response = await fetch('https://api.structocr.com/v1/receipt', { method: 'POST', headers: { Authorization: `Bearer ${import.meta.env.VITE_STRUCTOCR_KEY}` }, body: formData, });
3. 3

   Add your StructOCR API key to your environment

   In the Bolt.new file explorer, create or open the .env file to securely add your StructOCR key. The app will automatically reload with your live scanner.

What you can build in Bolt.new with this integration

• Corporate expense tracker: Let employees snap photos of their lunch or travel receipts and automatically populate a reimbursement tracker. Perfect for building custom expense management automation workflows.
• Loyalty & rewards scanning: Build a consumer app where users upload grocery receipts to prove purchase of specific brands and earn reward points automatically.
• Personal budgeting dashboard: Create a financial tool that reads your daily coffee and retail receipts, categorizes the spending, and calculates monthly totals — all inside Bolt.new.
• Tax preparation assistant: Parse hundreds of receipts to separate tax amounts and deductible expenses without manual data entry.

The prompt and the code

Copy the follow-up prompt into your Bolt.new chat to generate the integration. The code block shows what Bolt typically produces — useful if you want to verify or tweak it.

I need to add receipt OCR to this app.

When a user uploads an image:
1. Send it as multipart/form-data to: POST https://api.structocr.com/v1/receipt
2. Include the header: Authorization: Bearer ${VITE_STRUCTOCR_KEY}
3. The response is JSON with fields: merchant_name, date, time, total_amount, tax_amount, currency, items[]
4. Display each field in the results panel below the upload button
5. Show a loading spinner while the request is in flight
6. Show an error message if the upload fails

Use the environment variable VITE_STRUCTOCR_KEY for the API key.

What the API returns

Every field is labeled and typed. Your Bolt.new app can render this directly without any transformation.
