Monthly history since 2018

Spam-filtered scores

REST API + MCP server

A single number doesn't tell you enough

Is that domain getting stronger, or quietly fading? Is its authority real, or manufactured by a link network? A one-time score can't say, and checking domains one by one doesn't scale when you're weighing hundreds.

⚡

Everything in one call

Send up to 100 domains and get each one's current score and full monthly history in the same response. No second request.

📈

The trend, not a snapshot

Monthly data since 2018 shows whether authority is climbing, flat, or collapsing, so you value a domain on where it's heading.

🛡

Spam gets scored down

Domains that manufacture authority through link networks are detected and scored near zero, so you don't overpay for a gamed domain.

🌐

Open, not a black box

Scores are computed from Common Crawl's open web graph. You can read the method behind the number.

🤖
