DMarket

DMarket is a marketplace for trading in-game items and skins across titles like CS2 (CS:GO), Dota 2, Team Fortress 2, and Rust.

Requests authenticate with a public API key plus a per-request Ed25519 signature. DMarket was surfaced as a portfolio company of Pantera Capital. Sector: crypto / gaming.

DMarket publishes 6 APIs on the APIs.io network, including Account API, Aggregator API, Buy items API, and 3 more. Tagged areas include Company, Crypto, Gaming, Marketplace, and Trading.

DMarket’s developer surface includes authentication, documentation, API reference, getting-started guide, support, engineering blog, pricing, and 13 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime (on an ambiguous tag, where no other regime matched), so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/dmarket: open an issue to ask a question, or submit a pull request to add artifacts. Submit an artifact on GitHub — free → Manage your own listing — the Influence plan, $499/mo →

Something on this page wrong about DMarket? Report it → Free, always, and read by a human — corrections are worked from the queue daily. Agents can file the same report through the report_correction tool on the apis.io MCP.
