Xpansiv is market infrastructure for global environmental and energy commodities — carbon credits, renewable energy certificates, water, low-carbon fuels and recycled materials. It operates CBL, the largest spot exchange for environmental commodities, the Evolution Markets and OTX brokerage and execution desks, the H2OX water market and the ACE and JSEV carbon platforms, alongside the environmental registries it acquired with APX in 2022 — NAR (North American Renewables Registry), TIGR, I-REC, I-TRACK-G and the Xpansiv-powered digital fuels registries. Its public developer portal at developer.xpansiv.com publishes eleven OpenAPI descriptions across Xpansiv Connect (environmental commodity portfolio, retirement and transfer), Xpansiv Managed Solutions, the NAR and TIGR registry client APIs, the Optimal Outcomes suite and the APX Power Markets file registry, plus a FIX 4.4 marketplace protocol specification, Xpansiv Data market-data APIs and a first-party Python SDK.
Xpansiv publishes 6 APIs on the APIs.io network, including Connect API, Managed Solutions API, NAR Registry Client API, and 3 more. Tagged areas include Company, Environmental Commodities, Carbon Markets, Renewable Energy Certificates, and Registries.
Xpansiv’s developer surface includes documentation, API reference, getting-started guide, support, signup flow, engineering blog, authentication, and 23 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Energy & Utilities 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/xpansiv: open an issue to ask a question, or submit a pull request to add artifacts.
