📄 Quick Start Guide
Step 1: Select Base URL
We offer dedicated public cloud access endpoints for domestic and international users, with separate regional configurations. Connecting to the nearest node ensures fast and stable network calls. No account registration or API Key is required — you may send requests directly to the endpoints listed below.
| Environment | API Endpoint |
|---|---|
| Global | https://adp-global.laiye.com/public/v1/invoice-fast/extract |
| China | https://adp.laiye.com/public/v1/invoice-fast/extract |
Step 2: Send Request
Choose one file transfer method and send a POST request:
Method 1: File URL
curl -X POST "https://adp-global.laiye.com/public/v1/invoice-fast/extract" \
-H "Content-Type: application/json" \
-d '{
"file_url": "shturl.cc/vZd6rD9NxsmfNZPF5KjsnB78s"
}'
Method 2: Base64 Encoded File Content
curl -X POST "https://adp-global.laiye.com/public/v1/invoice-fast/extract" \
-H "Content-Type: application/json" \
-d '{
"file_base64": "<base64-encoded-file-content>"
}'
Request Example in Python:
import base64, requests
with open("invoice.pdf", "rb") as f:
b64 = base64.b64encode(f.read()).decode()
response = requests.post(
"https://adp-global.laiye.com/public/v1/invoice-fast/extract",
json={"file_base64": b64},
timeout=180,
)
print(response.json())
