Baidu OCR API Tutorial 2026 – Chinese Document Recognition Without a China Phone Number

Baidu OCR API Tutorial 2026: Recognize Chinese Documents Without a China Phone Number

🇨🇳 Chinese OCR Solution | Pay-as-you-go Baidu OCR via GoldBean — no China SIM, no deposit, $0.01/request


🌟 Why Baidu OCR Matters in 2026

Baidu OCR is widely considered the best Chinese-language OCR engine, with 96%+ accuracy on printed Chinese text. From invoice processing to ID card verification, it powers critical document workflows across finance, e-commerce, and enterprise SaaS.

But if you're a developer outside China, accessing it directly is a pain:

  • ❌ Need a Chinese phone number to register
  • ❌ Must complete real-name authentication
  • ❌ Have to pre-pay $100+ in a Chinese bank account

This 2026 tutorial shows you how to use Baidu OCR without any of that — via GoldBean, a pay-per-use API marketplace that wraps Baidu's 13 core AI APIs with a single global API key.


🚀 Quick Start (5 Minutes)

What You'll Need

  • An image with Chinese text (invoice, ID card, business license, or any document)
  • cURL, Python 3, or Node.js 18+

Step 1: Get Your API Key

# Register at https://goldbean-api.xyz

Step 2: Try It with cURL

curl -X POST https://goldbean-api.xyz/api/baidu/ocr/general-basic \

    {"words": "金额: ¥12,800.00"}
  ],
  "words_result_num": 3
}
Enter fullscreen mode Exit fullscreen mode

Step 3: Python OCR Integration

import requests
import base64

API_KEY = "your_goldbean_api_key"
BASE_URL = "https://goldbean-api.xyz/api/baidu/ocr"

# Encode image as base64
with open("invoice.jpg", "rb") as f:
    img_b64 = base64.b64encode(f.read()).decode()

# Call Baidu OCR general recognition
resp = requests.post(
    f"{BASE_URL}/general-basic",
    headers={"Authorization": f"Bearer {API_KEY}"},
    json={"image": img_b64}
)

data = resp.json()
for result in data.get("words_result", []):
    print(result["words"])
Enter fullscreen mode Exit fullscreen mode

Step 4: Node.js OCR Integration

const axios = require('axios');
const fs = require('fs');

const API_KEY = 'your_goldbean_api_key';
const BASE_URL = 'https://goldbean-api.xyz/api/baidu/ocr';

async function recognizeChineseText(imagePath) {
  const image = fs.readFileSync(imagePath).toString('base64');

  const response = await axios.post(
    `${BASE_URL}/general-basic`,
    { image },
    { headers: { Authorization: `Bearer ${API_KEY}` } }
  );

  response.data.words_result.forEach(r => console.log(r.words));
}

recognizeChineseText('./chinese-doc.jpg').catch(console.error);
Enter fullscreen mode Exit fullscreen mode
