# CloudWalk

> CloudWalk, Inc. is a payments and financial-infrastructure company (Sunnyvale, CA and São
> Paulo, Brazil) building an AI-native transaction layer for small businesses. It operates
> InfinitePay (Brazilian acquiring, digital banking, Tap to Pay, hosted checkout, Pix,
> credit), JIM (phone-as-POS for self-employed workers in the US) and Pierre (personal
> finance intelligence on Brazilian Open Finance). Its public developer surface is small and
> integration-shaped: a two-operation Integrated Checkout REST API, an approved-payment
> webhook, and an InfiniteTap deeplink handoff for Tap to Pay.

Generated by the API Evangelist enrichment pipeline on 2026-08-01. CloudWalk publishes no
llms.txt of its own (/llms.txt returned 404 on every host probed), no OpenAPI, no AsyncAPI,
no MCP server and no A2A agent card.

## Key facts

- Merchants are identified by their public InfiniteTag `handle` in the request body. There is
  no API key, token, OAuth or signature on the public API.
- Amounts are always integers in Brazilian cents (R$ 10,00 = 1000).
- Capture methods: `credit_card` (up to 12 installments) and `pix`.
- Errors use a proprietary `{success, message}` envelope, not RFC 9457 problem+json.
- There is no idempotency key. `order_nsu` is a correlation identifier only.
- The API is unversioned. The same operations answer on both `api.checkout.infinitepay.io`
  and the older `api.infinitepay.io/invoices/public/checkout` path.

## APIs

- [InfinitePay Checkout API](https://www.infinitepay.io/checkout-documentacao): create hosted
  checkout payment links and check their payment status. Base URL
  `https://api.checkout.infinitepay.io`.
  - `POST /links` — create a checkout payment link (`createCheckoutLink`)
  - `POST /payment_check` — check the payment status of a link (`checkPaymentStatus`)
  - webhook `payment_approved` — POSTed to the link's `webhook_url` when payment is approved;
    answer 200 to acknowledge, 400 to be retried.
- [InfiniteTap deeplink integration](https://www.infinitepay.io/checkout-tap): hand a Tap to
  Pay transaction from a third-party POS app to the InfinitePay mobile app via
  `infinitepaydash://infinitetap-app` and receive the result on your own return deeplink.
  Android 11+ with NFC, or iOS with Apple Tap to Pay.
