Patch

Patch is an API-first climate platform that helps companies procure carbon credits and removals, run climate strategy programs, and embed climate action into their own products. The core Patch API exposes carbon projects, estimates, and orders so developers can build offset purchase flows directly into checkouts, accounting systems, and ESG products. Patch also runs Radius (network-based impact acceleration), Offtake (climate tech funding and long-term credit access), and an RFP tool for carbon credit procurement. Official SDKs are available for Node.js, Python, Ruby, and other languages, and the API is documented with an OpenAPI 3 spec and Swagger UI.

Patch publishes 4 APIs on the APIs.io network, including Order Line Items API, Orders API, Projects API, and 1 more. Tagged areas include Climate, Carbon Credits, Carbon Removal, Offsets, and API-First.

The Patch catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Patch’s developer surface includes authentication, documentation, GitHub presence, engineering blog, pricing, and 16 more developer resources.

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