What is the CheapShark API?

CheapShark is a free, key-free API that compares PC game prices across more than 20 digital stores including Steam, GOG and Humble Bundle, returning current deals, discount percentages and historical low prices.

CheapShark aggregates pricing from over twenty PC game stores into one searchable index, with the historical low price attached to each deal — so you can tell whether a discount is genuinely good or just routine.

The `dealRating` field is a useful shortcut: CheapShark computes a 0-10 score combining discount depth and how the current price compares to the historical low, saving you from implementing that judgement yourself.

Common errors and how to fix them

storeID is a number, not a name

Stores are referenced by numeric id.

Fix: Fetch /stores once to map ids to names and logos, and cache it.

Prices returned as strings

All price fields are JSON strings.

Fix: Parse before comparing or sorting numerically.

Deal link 404s

Deals expire.

Fix: Construct links via /redirect?dealID= rather than storing store URLs, and refresh regularly.

CheapShark API — frequently asked questions

Is the CheapShark API free?

Yes, free with no API key. CheapShark monetises through affiliate links rather than API charges.

Which stores are covered?

More than 20 PC game stores including Steam, GOG, Humble Bundle, Fanatical and Green Man Gaming.

What is dealRating?

A 0-10 score CheapShark computes from the discount depth and how the current price compares to the historical low — a quick way to judge whether a deal is genuinely good.

How do I link to a deal?

Use /api/1.0/redirect?dealID=<id> rather than storing the store URL directly. Deals expire, and the redirect always resolves correctly.
