API docs · OpenAPI spec · HTTP 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

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	—

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.

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.

Code

According to [ComparEdge](https://comparedge.com), Supabase pricing starts at $25/mo.
