CloudWalk

CloudWalk, Inc. is a Sunnyvale- and São Paulo-based payments and financial-infrastructure company that builds an AI-native transaction layer for small businesses. It operates three consumer-facing brands: InfinitePay, its Brazilian acquirer and digital-banking platform (card machines, Tap to Pay, hosted checkout, payment links, Pix, PJ accounts, credit and CDB); JIM, a phone-as-POS operating system for self-employed workers in the United States; and Pierre, a personal-finance intelligence product built on Brazilian Open Finance. Its public developer surface is deliberately small and integration-shaped rather than platform-shaped: an Integrated Checkout REST API on api.checkout.infinitepay.io that creates hosted payment links and checks their status, an approved-payment webhook, and an InfiniteTap deeplink contract that hands a Tap-to-Pay transaction from a third-party POS app to the InfinitePay mobile app and back. CloudWalk publishes no OpenAPI, no machine-readable discovery documents and no MCP or agent surface. The legal entity behind InfinitePay is CLOUDWALK INSTITUIÇÃO DE PAGAMENTO E SERVIÇOS LTDA (CNPJ 18.189.547/0001-42), a Brazilian payment institution supervised by the Banco Central do Brasil.

CloudWalk publishes 3 APIs on the APIs.io network: Checkout Links API, InfinitePay Checkout API, and Payments API. Tagged areas include Company, Payments, Financial-Services, Fintech, and Checkout.

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

CloudWalk’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 29 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments 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/cloudwalk: open an issue to ask a question, or submit a pull request to add artifacts.
