n8n is an open-source, self-hostable workflow automation tool — like Zapier, but running on your own infrastructure. Full data sovereignty, no vendor lock-in.
n8n's HTTP Request node hits ToolCenter directly. Combine with n8n's JavaScript/Python code nodes, conditional logic, and cron triggers and you have a full automation pipeline with zero third-party cloud.
Method POST · URL https://api.toolcenter.dev/v1/scrape.

{ "url": "{{ $json.url }}" } — use n8n expressions to plug values from upstream nodes.
A real pipeline you can copy-paste. Adjust the trigger and endpoint for your stack.

You know about pricing changes before the competitor announces them.
Self-hosted means you run the postgres, redis, and n8n processes. Use n8n-hosted if you want managed — it still talks to ToolCenter.
Free tier covers 100 calls — enough to stand up the pipeline before committing. No credit card, no gotchas.
