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
- A GoldBean account ($1 deposit, supports PayPal/Alipay/USDC)
- 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
# Deposit $1+ → Copy your API key
Step 2: Try It with cURL
curl -X POST https://goldbean-api.xyz/api/baidu/ocr/general-basic \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"image": "https://example.com/chinese-invoice.jpg"}'
Response:
{
"words_result": [
{"words": "增值税发票"},
{"words": "发票代码: 3100245678"},
{"words": "金额: ¥12,800.00"}
],
"words_result_num": 3
}
Step 3: Python OCR Integration
import requests
import base64
API_KEY = "your_goldbean_api_key"
BASE_URL = "https://goldbean-api.xyz/api/baidu/ocr"
# Encode image as base64
with open("invoice.jpg", "rb") as f:
img_b64 = base64.b64encode(f.read()).decode()
# Call Baidu OCR general recognition
resp = requests.post(
f"{BASE_URL}/general-basic",
headers={"Authorization": f"Bearer {API_KEY}"},
json={"image": img_b64}
)
data = resp.json()
for result in data.get("words_result", []):
print(result["words"])
Step 4: Node.js OCR Integration
const axios = require('axios');
const fs = require('fs');
const API_KEY = 'your_goldbean_api_key';
const BASE_URL = 'https://goldbean-api.xyz/api/baidu/ocr';
async function recognizeChineseText(imagePath) {
const image = fs.readFileSync(imagePath).toString('base64');
const response = await axios.post(
`${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);
