Celsius Network

Celsius Network LLC was a global cryptocurrency lending, custody and yield platform, founded in 2017, that let retail and institutional customers earn interest on crypto deposits, borrow US dollars and stablecoins against their holdings, and — through the Celsius Partner API — let third-party partners embed that earning power directly into their own applications. The Partner (Wallet) API exposed per-coin balances, accrued interest, transaction history, deposit addresses, withdrawals, KYC verification and utility reference data across three partnership models: Omnibus Integration, Omnibus Treasury, and Segmented Integration, where the partner created and managed a Celsius wallet for each of its own end users. Celsius froze withdrawals on 2022-06-12, filed for Chapter 11 bankruptcy on 2022-07-13, had its plan of reorganization confirmed on 2023-11-09, emerged on 2024-01-31 and shut down its mobile and web applications on 2024-02-29 as part of the wind-down of its business operations. The Partner API and the developer portal are retired and their hosts no longer resolve. The reorganized bitcoin-mining business was spun out as Ionic Digital, a separate company that listed on Nasdaq under IOND on 2026-07-28. This profile preserves the API contract as a historical record, derived entirely from first-party artifacts that are still publicly resolvable.

Celsius Network publishes 4 APIs on the APIs.io network, including KYC API, Users API, Utility API, and 1 more. Tagged areas include Company, Cryptocurrency, Digital Assets, Financial-Services, and Lending.

Celsius Network’s developer surface includes documentation, API reference, support, authentication, changelog, sandbox, and 21 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments 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/celsius-network: open an issue to ask a question, or submit a pull request to add artifacts.
