Dunamu

Dunamu Inc. (두나무 주식회사) is a South Korean fintech and blockchain company founded in April 2012 and headquartered at 369 Gangnam-daero, Seocho-gu, Seoul. Dunamu operates Upbit, Korea's largest digital asset exchange (launched 2017, the country's first registered VASP), and Stockplus, a securities trading application launched in 2014, alongside Stockplus Unlisted for pre-IPO share trading. The group also spun out Lambda256 (blockchain infrastructure, now trading as Nodit) in 2019 and runs the Dunamu & Partners venture arm. Dunamu itself publishes no developer program at dunamu.com — its entire public API surface is served under the Upbit brand through the Upbit Developer Center, which offers REST and WebSocket APIs for market data, orders, accounts, deposits, withdrawals and Travel Rule compliance, plus first-party Python, TypeScript and Go SDKs, a CLI and packaged agent skills published from the upbit-official GitHub organization. That API surface is catalogued separately at the Upbit provider profile; this record profiles the corporate parent.

Dunamu publishes 2 API contracts indexed on the APIs.io network: Exchange API and Quotation API. Tagged areas include Fintech, Cryptocurrency, Digital Assets, Exchange, and Securities.

The Dunamu catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Dunamu’s developer surface includes pricing, CLI, changelog, authentication, documentation, API reference, getting-started guide, and 38 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime, 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.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% 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/dunamu: open an issue to ask a question, or submit a pull request to add artifacts.
