How to Use SEO Metrics APIs for Link Building Automation

Why Manual Link Prospecting Doesn't Scale

Link building is one of the most labor-intensive parts of SEO. Vetting 500 prospects by hand — checking domain authority, relevance, and contact details — can take days.

SEO metrics APIs change this. With a simple HTTP request, you can programmatically check any domain's authority-style score and filter your prospect list automatically.

Building a Basic Qualification Workflow

Here is a simple Python script that checks a list of domains and filters for those with a domain rating above a threshold:

import requests

domains = ["example.com", "blog.com", "seosite.net"]
threshold = 30

for domain in domains:
    r = requests.get(
        "https://seo.basantasapkota.com/api/seo",
        params={"url": domain}
    )
    data = r.json()
    if data.get("domain_rating", 0) >= threshold:
        print(f"QUALIFIED: {domain} — DR {data['domain_rating']}")
    else:
        print(f"REJECTED: {domain} — DR {data['domain_rating']}")

Running This in n8n

Using n8n, you can build a no-code version of this workflow:

1. Google Sheets node — Pull your prospect list

2. HTTP Request node — Call the Basanta SEO API for each domain

3. IF node — Filter domains with DR >= your threshold

4. Airtable / Google Sheets node — Save qualified leads
