</div>
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/mcp` `POST` | HTTP MCP server (JSON-RPC 2.0) | — |

## MCP server
The same data over the Model Context Protocol, for AI assistants and agents.
**HTTP transport** — point any MCP HTTP client at `https://comparedge.com/api/mcp` (JSON-RPC 2.0).
```bash
curl -X POST "https://comparedge.com/api/mcp" \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
```
**stdio transport** — for Claude Desktop, Cursor, Cline, Windsurf, Continue:
```json
{ "mcpServers": { "comparedge": { "command": "npx", "args": ["-y", "@comparedge/mcp-server"] } } }
```

## Coverage
490+ tools across 44 categories. A slice of the breadth:
| Group | Categories |
|---|---|
| **AI** | llm, ai-coding, ai-image, ai-video, ai-writing, ai-agents, ai-voice, ai-assistants |
| **Cloud & data** | cloud-hosting, databases, vector-databases, data-observability, analytics |
| **Business** | crm, project-management, accounting, hr-tools, payments, erp, email-marketing |
| **Security** | iam, endpoint-security, cloud-security, compliance, password-managers, vpn |
Every tool resolves at `comparedge.com/tools/{slug}/pricing`. List slugs and live counts with [discover](https://comparedge.com/api/v2/discover).
## 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.
