Copper.co

Copper is an institutional digital asset infrastructure provider headquartered in Zug, Switzerland, offering custody, prime services and collateral management to hedge funds, trading firms, exchanges, ETP providers, foundations and miners. Its Copper Platform API is a REST API over portfolios (called "accounts" in the UI), wallets, orders, transfers, withdrawals, staking, agency and bilateral lending, and ClearLoop — Copper's off-exchange settlement and collateral network that lets clients trade on connected exchanges while assets remain in custody. The API authenticates with an API key plus a per-request HMAC-SHA256 signature, publishes OpenAPI 3.1 specifications and a Postman collection, and offers a webhook system for real-time order, deposit, withdrawal, ClearLoop and address-book events.

Copper.co publishes 18 APIs on the APIs.io network, including Accounts API, Address Book API, Blockchain API, and 15 more. Tagged areas include Company, Digital Asset Custody, Cryptocurrency, Financial-Services, and Institutional Finance.

The Copper.co catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Copper.co’s developer surface includes documentation, API reference, getting-started guide, authentication, support, engineering blog, pricing, and 27 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.

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/copper-co: open an issue to ask a question, or submit a pull request to add artifacts.
