The data

What you get per item

Not just "a price" — the whole market picture, cross-referenced across every market we track and normalised into one schema.

Best priceprices.best · bestSource

The lowest price across every market we track. Capped Steam listings can't fake-win.

Steam priceslatest · median · buyorder

Lowest ask, median sale and highest buy order with volume — straight from the source.

Real valuereal · realMedian

Lowest and median across 3rd-party markets — what the item actually trades for.

Price history?source=steam · markets

Steam's daily median-sale price is the long-term backbone; every third-party market is served as daily lowest ask — one consistent metric per source.

Doppler phasesvariants · ?source=phases

Per-phase prices Steam can't show — Ruby, Sapphire, Emerald, Black Pearl and Phase 1–4, each with its own cross-market low and daily history.

FAQ

Common questions

faq

What is the Steam Data API?

A fast, self-hosted REST API for Counter-Strike 2 (CS2) and Rust market data — live prices, daily price history, multi-marketplace comparison and item metadata. It's a developer-friendly, lower-cost alternative to scraping the Steam Community Market yourself or paying for pricey data subscriptions.

Which games and marketplaces are covered?

CS2 is priced from the Steam Community Market plus CSFloat, Skinport, WhiteMarket, DMarket and Waxpeer — six markets on one request. Rust is priced from Steam, Skinport, DMarket and Waxpeer. Browse everything in the API docs.

How is this different from steamwebapi?

Same core idea — one API for Steam market prices — but Steam Data API compares six marketplaces per item with a computed best price and spread, ships daily sales history back to 2020, covers both CS2 and Rust, and starts free. See pricing.

How far back does the price history go?

Steam's official median-sale series is the long-term backbone — for each item it reaches back as far as Steam publishes (up to 2013 for older skins). Every third-party market (CSFloat, Skinport, WhiteMarket, DMarket, Waxpeer) is served as a daily lowest-ask series that accrues going forward. Choose with ?source=steam or ?source=markets.

What price data do I get for each item?

Lowest ask, latest and median sale price, highest buy order, a cross-market “real” value, the computed best price (lowest across every market) and 24h sold volume. The markets endpoint adds the full per-marketplace breakdown with spread, and the history endpoints return daily series.

How often is the data updated?

Continuously. The catalog is swept on a rolling schedule and prices are refreshed throughout the day, so most fields stay fresh to within minutes.

How do I get an API key and authenticate?

Create a free key in your dashboard, then send Authorization: Bearer sdk_… on every request. Rate limits and monthly quota scale with your plan.

Is there a free plan?

Yes — the Free plan lets you build and test at no cost, and paid plans start at $10/mo. Every plan covers CS2 + Rust and 30+ currencies; higher tiers unlock more endpoints — inventory lookups on Pro+, price history and cross-market comparison on Scale. Compare plans →

What can I build with it?

Inventory value calculators, price-alert Discord bots, CS2 and Rust trading bots, marketplace price-comparison sites and market-analytics dashboards. Read 5 things you can build with a Steam market API →

Can I get prices in my local currency?

Yes — add ?currency=EUR (or any of 30+ currencies). Conversion uses daily ECB reference rates.
