Pricing Data: SaaS, AI & LLM Cost API | ComparEdge

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.

Full schemas: openapi.json or the live OpenAPI spec.

Quick start

# 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"

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

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);

curl -X POST "https://comparedge.com/api/mcp" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Coverage

490+ tools across 44 categories. A slice of the breadth:

Every tool resolves at comparedge.com/tools/{slug}/pricing. List slugs and live counts with 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.

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.
