What is Backlinq?

SEO Backlink
Intelligence Unbundled

Clean REST API

Four predictable endpoints with consistent JSON responses

No Bloat

Just the data you need. No dashboards you'll never open.

AI Agent Ready

Listed on CTX Protocol. Machines consume autonomously.

Multi-Source

Aggregated from Moz, Open PageRank, and Common Crawl.

The Problem

SEO tools have a pricing problem

Legacy platforms are built for enterprise marketing teams. Developers and indie agencies pay the price.

$1,200+

$1,200/year minimum

Ahrefs, SEMrush, and Moz Pro charge enterprise prices for features most developers never use.

12mo

Annual lock-in

Pay for 12 months whether you use it or not. No flexibility for seasonal projects.

$449+

API is premium

Programmatic access locked behind expensive tiers or priced per-seat instead of per-query.

Three sources. One API.
