Add National ID OCR to Your Lovable.dev App in 5 Minutes

The problem: Standard AI hallucinates PII and fails on holograms

Tools like Lovable.dev are remarkable at generating apps — 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, Lovable can wire it up from a single fetch call.

Integrate StructOCR in Lovable (3 Steps)

1. 1

   Create a Lovable project and describe your app

   Open lovable.dev and start a new project. In the chat box, 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."
2. 2

   Tell Lovable to call the StructOCR API

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

   💬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."

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

   Add your StructOCR API key and publish

   Go to Project Settings → Environment Variables in Lovable and add your StructOCR key. Then hit Publish. Your ID scanner is live.

What you can build in Lovable 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 Lovable prompt into your project chat to generate the integration. The JavaScript tab shows what Lovable produces — useful if you want to verify or customize it.

Prerequisite: A free StructOCR account — get your API key at structocr.com/dashboard (no credit card required)

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 Lovable app can bind this directly to the UI.
