Free REST API and MCP server for verified SaaS, AI, and LLM pricing across 490+ tools. OpenAPI 3.1, no API key.
Documentation
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.
| Endpoint | Returns | Key params | |
|---|---|---|---|
| `/api/v2/pricing/{slug}` | Full sourced pricing record for one product | `depth=summary\ | full`, `fields=` |
| `/api/v2/pricing` | Batch pricing records, up to 20 | `slugs=a,b,c` | |
| `/api/v2/compare` | Side-by-side comparison of 2 to 4 products | `slugs=`, `seats=` | |
| `/api/v2/discover` | Find software by criteria | `category=`, `maxPrice=`, `hasFreeTier=` | |
| `/api/v2/history/{slug}` | Price-stability signal, latest snapshot, trend | — | |
| `/api/v2/coverage` | Per-field availability, freshness, and license | `slugs=`, `fields=` | |
| `/api/v2/usage/{slug}` | LLM / API usage rate card, with optional estimate | `inputTokens=`, `outputTokens=` | |
| `/api/v2/tco` `POST` | Team total cost of ownership, sourced line items | `slug`, `seats`, `billing` | |
| `/api/v2/cost-guide/{slug}` | Negotiation-ready true-cost brief: renewal-rate costs, transparency score, discount programs, tactics with expected discounts, and a free negotiation email generator | — | |
| `/api/mcp` `POST` | HTTP MCP server (JSON-RPC 2.0) | — |

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.
