21Shares

21Shares AG is a Swiss-headquartered issuer of physically backed cryptocurrency exchange-traded products (ETPs), founded in 2018 as Amun AG and part of the 21.co group. It runs the largest suite of crypto ETPs in the world — single-asset, staking, and index/basket products covering Bitcoin, Ethereum, Solana, XRP and dozens of other assets — listed on regulated European exchanges including SIX Swiss Exchange, Xetra and Euronext, and distributed through banks and brokers. The product is a regulated financial instrument, not software: 21Shares publishes no developer program, no public API reference and no SDKs. What it does publish machine-readably is regulatory distribution data — the FinDatEx European MiFID Template (EMT V4.2), European PRIIPs Template (EPT) and European ESG Template (EET V1.1.3) spreadsheets covering its full ETP range with ISINs, costs and target-market data — plus PRIIPs KIDs, prospectuses, final terms and factsheets as PDFs, and an RSS research feed.

21Shares is profiled on the APIs.io network. Tagged areas include Company, Financial Services, Asset Management, Cryptocurrency, and Exchange Traded Products.

21Shares’ developer surface includes support, engineering blog, YouTube channel, and 15 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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

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/21shares: open an issue to ask a question, or submit a pull request to add artifacts.

  detail: 21Shares AG issues regulated crypto exchange-traded products, not software — its published sitemap carries 8,267
    URLs across 13 locales with no developer, API or docs page anywhere in it, and the one API host on its own domain (data.21shares.com,
    an AWS API Gateway) answers 403 Forbidden to every path and method, undocumented; the only machine-readable data it distributes
    is the FinDatEx EMT/EPT/EET spreadsheet family on its CDN.
