Koinex

Koinex was an Indian digital-asset exchange launched in 2017, describing itself as India's first and largest cryptocurrency exchange with more than one million users. It offered spot trading across multiple crypto assets with INR pairs before regulatory uncertainty around Indian banking access forced it to shut down all services in June 2019, asking users to withdraw their holdings by July 15, 2019. The company is DEFUNCT: koinex.in now serves only a single static wind-down notice directing former users to claim any crypto assets left on the platform through CoinDCX, with which Koinex partnered for the transition. There is no live product, developer portal, documentation, or API surface; the domain's TLS certificate expired in March 2025 and every path other than the notice returns 403. Retained in the API Evangelist network as a historical record of a shut-down crypto exchange and as a Pantera Capital portfolio lead.

Koinex is profiled on the APIs.io network. Tagged areas include Company, Crypto, Cryptocurrency Exchange, Digital Assets, and Trading.

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