How do I access public records data through an API?

Accessing public records data through an API usually looks like this:

1) Find the data source

Public records may be exposed by:

• Government open data portals
• Court, property, business, or licensing databases
• Third-party aggregators that republish public records

Look for:

• API documentation
• Terms of use
• Rate limits
• Authentication requirements

2) Get an API key if needed

Many APIs require you to:

• Create an account
• Request an API key or token
• Accept usage restrictions

3) Read the endpoint docs

Identify:

• Base URL
• Endpoints for the records you need
• Required query parameters
• Response format, usually JSON or CSV

Example:

GET https://api.example.gov/records?state=CA&type=property
Authorization: Bearer YOUR_API_KEY

4) Make a request

You can use tools like:

• curl
• Python requests
• JavaScript fetch

Example in Python:

import requests

url = "https://api.example.gov/records"
headers = {
    "Authorization": "Bearer YOUR_API_KEY"
}
params = {
    "state": "CA",
    "type": "property"
}

response = requests.get(url, headers=headers, params=params)
print(response.status_code)
print(response.json())

5) Handle pagination and filtering

Public records APIs often return data in pages, so check for:

• page
• limit
• offset
• next_cursor

Example:

params = {"limit": 100, "offset": 0}

6) Respect legal and privacy limits

Even if records are public, APIs may restrict:

• Bulk downloading
• Commercial use
• Reuse of personal data
• Automated scraping

Always review:

• API terms
• Privacy laws
• Agency-specific rules

7) Process and store the data carefully

Common steps:

• Validate fields
• Normalize dates/addresses/names
• De-duplicate records
• Log request IDs for debugging
