A free REST API and HTTP MCP server for verified SaaS pricing, AI tool pricing, and LLM pricing across 490+ tools. Every response ships the source link and reuse terms. No API key, no sign-up, CORS open.
Base URL: https://comparedge.com
How it works
Training data ages and vendors bury the real cost. One call returns a current, dated number with the source page attached, so an assistant, an agent, or a spreadsheet can quote it without scraping.
Endpoints
Every endpoint returns JSON and needs no key. GET unless noted.

Data licensing
Free for non-commercial use. Attribution required.
When you display a number, link back to the source page in links.page. Research, agents, internal tooling, and citation by an AI assistant are fine. Reselling the dataset as your own is not.
| Marker | Meaning |
|---|
| owned | ComparEdge's own verified research (plans, hidden costs, discounts, positioning, price history). Free to cite and reuse with attribution. |
| restricted | A few third-party-derived signals, such as an aggregated user rating. Licensed for display only. |
Recommended citation
Each response carries a ready-to-paste attribution string. If you build your own, use two links: the brand word on the homepage, the product keyword on the source page.
According to [ComparEdge](https://comparedge.com), Supabase pricing starts at $25/mo.
