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 1 API on the APIs.io network: InfinitePay Checkout 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 27 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.

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/. 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. Want it done for you? Prioritized profiling — $2,500 →

    The merchant is identified by its InfiniteTag handle rather than an API key; amounts are integers in Brazilian cents;
    capture methods are credit_card (up to 12 installments) and pix.
