**[API docs](https://comparedge.com/api-docs) · [OpenAPI spec](https://comparedge.com/api/v2/openapi.json) · [HTTP MCP](https://comparedge.com/api/mcp)**






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



![Ask the API, get a sourced record, cite it with a link back](https://raw.githubusercontent.com/comparedge/pricing-api/main/assets/how-it-works.svg)



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) | — |

## Quick start



```bash

# One product, summary view

curl "https://comparedge.com/api/v2/pricing/notion?depth=summary"



# Compare two tools

curl "https://comparedge.com/api/v2/compare?slugs=notion,coda"



# Find databases with a free tier

curl "https://comparedge.com/api/v2/discover?category=databases&hasFreeTier=true&limit=5"

```



Python



```python

import requests



r = requests.get("https://comparedge.com/api/v2/pricing/supabase", params={"depth": "summary"})

data = r.json()



print(data["name"], data["priceRange"]["display"])

for tier in data["tiers"]:

    print(f'  {tier["name"]}: ${tier["price"]}/{tier["period"]}')



print(data["attribution"])  # ready to paste, with the source link inside

```



Node.js



```js

const res = await fetch("https://comparedge.com/api/v2/pricing/supabase?depth=summary");

const data = await res.json();



console.log(data.name, data.priceRange.display);

console.log("Source:", data.links.page);

```



More runnable snippets: [`examples/`](./examples).

## 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



![Tools tracked per category across 44 categories](https://raw.githubusercontent.com/comparedge/pricing-api/main/assets/coverage.svg)



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.
