Safello

Safello is a Swedish cryptocurrency brokerage founded in 2013, registered with the Swedish Financial Supervisory Authority (Finansinspektionen) and listed on Nasdaq First North Growth Market since 2021. It lets people buy, sell, trade, and store digital assets, and exposes a "Cryptocurrency as a Service" (CaaS) Institutional API so third-party organisations can embed crypto buying/selling, BankID customer onboarding, KYC and compliance verification, market data, order management, and wallet balances. The v2 Institutional API (base https://api.safello.com) uses OAuth2 with client-credentials, authorization-code, and a custom Swedish BankID grant, plus a staging environment at api.s4f3.io for testing.

Safello publishes 7 APIs on the APIs.io network, including account API, auth API, compliance API, and 4 more. Tagged areas include Company, Fintech, Cryptocurrency, Bitcoin, and Brokerage.

Safello’s developer surface includes documentation, API reference, getting-started guide, support, pricing, signup flow, authentication, and 24 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.
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/. This rating is computed from github.com/api-evangelist/safello: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
