CoinAPI is a financial data and execution platform delivering normalized real-time and historical cryptocurrency market data and trade execution across more than 350 exchanges. Its product family covers a Market Data API (REST, WebSocket, FIX, and flat-file S3 delivery) for trades, quotes, order books, OHLCV, exchange rates, and derivatives metrics; an EMS Trading API (Execution Management System) that lets users place, manage, and route orders across multiple venues through one normalized REST/WebSocket/FIX interface; and Index and Metrics APIs that aggregate cross-exchange data into reference indexes and risk metrics. FIX endpoints (fix.coinapi.io) use GeoDNS to route to the nearest datacenter for low-latency connectivity.
CoinAPI publishes 1 API on the APIs.io network: Market Data API. Tagged areas include Blockchain, Crypto Indexes, Crypto Metrics, Cryptocurrency, and EMS.
The CoinAPI catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.
CoinAPI’s developer surface includes documentation, pricing, changelog, GitHub presence, engineering blog, and 7 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/coinapi: open an issue to ask a question, or submit a pull request to add artifacts.
