Built for developers who manage links at scale

Whether you're an affiliate site, SEO tool, or content platform — broken links cost money.

Affiliate Link Monitoring

Detect when affiliate parameters get stripped during redirects. Catch revenue leaks before they compound.

SEO Tool Integration

Pipe URLs from your CMS or SEO crawler into the API. Get broken link data without building your own checker.

CI/CD Pipelines

Check outbound links before deploying content. Catch dead links in staging, not production.

Scheduled Monitoring

Full async site scans with webhook callbacks. Know the moment a link breaks on your site.

Four endpoints. Full workflow.
