Secure API proxy for construction suppliers – one endpoint, unlimited integrations.
Solo founders building construction inventory apps struggle to integrate with suppliers' APIs without a development team.
BuildProxy acts as a unified proxy gateway, handling auth, rate limits, and retries for multiple supplier APIs behind a single, secure endpoint. Solo founders call yourapp.buildproxy.com/suppliers/{id}/inventory?sku=abc to fetch normalized data instantly. Deploy webhooks for changes without touching supplier auth in your app.
