Add National ID OCR to Your Bolt.new App in 5 Minutes
Bolt.new scaffolds your full-stack UI. StructOCR reads the identity cards. Here's the exact prompt and API call to wire them together for instant KYC — right in your browser.

Why Bolt.new + StructOCR is a natural fit for Identity Verification
Bolt.new generates and runs full-stack web applications directly in your browser. It handles the UI, components, and package management automatically — but securely extracting names, birth dates, and MRZ codes from a laminated ID card photo is something you have to wire up yourself. StructOCR fills exactly that gap: one API call, structured JSON back. Tell Bolt what you want, paste in the fetch code below, and your onboarding flow is ready.
The problem: Standard AI hallucinates PII and fails on holograms
Tools like Bolt.new are remarkable at generating apps instantly — but they stop at the file boundary. You can build a beautiful KYC upload interface in minutes, yet the actual extraction of names, document numbers, and MRZ lines from a laminated ID card requires a dedicated National ID OCR API. Standard vision models routinely misread security fonts, hallucinate personal data, or fail entirely on holographic overlays and glare.
The solution: Global ID parsing, instantly
StructOCR's /v1/national-id endpoint accepts a photo and returns a clean JSON object with the validated identity fields. It automatically decodes Machine Readable Zones (MRZ) and handles complex, localized ID layouts. 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)
Create a Bolt.new project and describe your app
Open bolt.new and start a new prompt. Describe the identity verification tool you want to build — be specific about the fields you need.
Try this prompt: "Build a mobile-friendly KYC onboarding app. Users can upload a photo of their National ID card, and the app will display the extracted full name, document number, date of birth, and address."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/national-id 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/national-id', { method: 'POST', headers: { Authorization: `Bearer ${import.meta.env.VITE_STRUCTOCR_KEY}` }, body: formData, });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
- Fintech onboarding (KYC): Let users snap a photo of their ID to instantly populate sign-up forms without manual typing, drastically reducing drop-off rates in financial onboarding flows.
- Gig economy driver signup: Build a mobile portal where contractors upload their ID cards for instant identity verification, a crucial step for mobility and delivery apps.
- Age verification gates: Create a tool that scans a user's ID, calculates their age based on the extracted `date_of_birth`, and conditionally grants access to age-restricted goods or services.
- Visitor management systems: Add an upload step to a corporate check-in flow: extract visitor details automatically from their national ID to print temporary badges in seconds.
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 National ID OCR to this app.
When a user uploads an image:
1. Send it as multipart/form-data to: POST https://api.structocr.com/v1/national-id
2. Include the header: Authorization: Bearer ${VITE_STRUCTOCR_KEY}
3. The response is JSON with fields: data.surname, data.given_names, data.document_number, data.date_of_birth, data.address
4. Display the extracted identity data in a clear, formatted profile card
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
A comprehensive JSON object containing both primary identity fields and specialized MRZ strings. Your Bolt.new app can bind this directly to the UI components.
