Coin Metrics

Coin Metrics is a Boston-based crypto financial intelligence provider founded in 2017, selling institutional-grade cryptoasset network (on-chain) data, exchange market data (trades, quotes, order books, candles, derivatives), CMBI indexes, reference rates, and reference/security-master data. Everything is delivered through a single documented API v4 - REST at api.coinmetrics.io/v4 and WebSocket streaming at wss://api.coinmetrics.io/v4 as paid, API-key products - plus a free, keyless Community API at community-api.coinmetrics.io/v4 under a CC BY-NC 4.0 license, with flat files, Python and R clients, and Google Sheets as additional delivery channels. A complete OpenAPI 3.0.2 definition is published on the docs site. Coin Metrics is now part of Talos: coinmetrics.io 301-redirects to talos.com/our-solutions/data/overview, while docs.coinmetrics.io and the api/community-api hosts remain live under the Coin Metrics brand.

Coin Metrics publishes 19 APIs on the APIs.io network, including Blockchain Explorer Job API, Blockchain Metadata API, Catalog API, and 16 more. Tagged areas include Financial, Market Data, Crypto, Blockchain, and On-Chain Data.

The Coin Metrics catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Coin Metrics’ developer surface includes authentication, developer portal, documentation, engineering blog, pricing, support, API reference, and 25 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 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/coin-metrics: open an issue to ask a question, or submit a pull request to add artifacts.
