Erebor

Erebor is a digital-first, FDIC-insured national bank built for the innovation economy — technology startups, cryptocurrency and stablecoin businesses, and AI and defense companies that traditional banks have historically underserved. Co-founded by Palmer Luckey (Anduril) and Joe Lonsdale (8VC) and backed by Founders Fund, Lux Capital, Haun Ventures, and 8VC, Erebor received OCC preliminary conditional approval in October 2025, FDIC deposit-insurance approval in December 2025, and launched in February 2026. It offers deposit accounts, wires and money movement, and stablecoin operations. Erebor exposes a developer API at api.erebor.bank secured with API keys, an Auth0-authenticated developer dashboard at developer.erebor.bank, and Fern-based developer documentation at docs.erebor.bank. The public developer docs are login-gated, so the machine-readable surface captured here is limited to what is observable without credentials.

Erebor publishes 1 API on the APIs.io network. Tagged areas include Company, Fintech, Banking, Digital Bank, and Stablecoin.

Erebor’s developer surface includes documentation, API reference, signup flow, authentication, sandbox, and 9 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Banking & Open Finance 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/.

    at api.erebor.bank authenticates requests with an API key and returns a structured JSON error envelope ({docs_url, error,
