INXY Payments

  • Name: INXY Payments
  • URL: https://www.inxy.io/
  • Category: crypto payment gateway / stablecoin payments API / merchant checkout-and-webhook infrastructure
  • Summary: INXY Payments is a hosted merchant-payments and stablecoin-processing stack. The evidence here is thinner than for larger payment operators, but it is enough: first-party site titles and SDK repos show checkout-session creation, redirect-to-pay flows, signed webhooks, and request-signature tooling for businesses that do not want to build that backend themselves. Useful note, but keep it in scale — this looks like a small operator-facing payments layer, not a category anchor.
  • What it does:
    • Offers a crypto payment gateway for businesses that want to accept digital-asset payments through hosted checkout flows
    • Positions a fintech-oriented API surface around stablecoin payments infrastructure rather than only consumer checkout widgets
    • Publishes an official merchant SDK that creates multi-currency payment sessions and redirects users into an INXY-hosted payment page
    • Supports webhook-driven payment lifecycle handling, including initial payment creation, waiting-confirmation states, received-payment events, and partial-payment handling
    • Publishes a separate JavaScript signature SDK for RSA/PEM-based request signing, suggesting additional authenticated API surfaces beyond the merchant checkout flow
    • Maintains official GitHub repositories under the inxy-payments organization as a substantive first-party developer surface
  • Key claims:
    • The homepage title positions INXY as a “Crypto Payment Gateway for Business,” which is the clearest first-party framing of the company’s core product surface in this pass
    • The fintech page title explicitly calls the offering “Fintech Crypto API & Stablecoin Infrastructure,” indicating the company wants to be understood as programmable infrastructure and not only a merchant plugin
    • Official-site search results for those pages describe INXY as providing secure solutions to accept, send, and manage cryptocurrencies and say the fintech API lets builders plug stablecoin payments, payouts, and conversions into their products without building a full crypto engine
    • The official PHP merchant-sdk README shows developers installing the SDK via Composer, creating a MultiCurrencySessionRequest, selecting supported assets such as USDT on Ethereum and BNB Smart Chain, BTC, ETH, DOGE, and USDC, and then redirecting customers to the payment page returned by the API
    • The same merchant SDK README documents webhook validation via an X-INXY-Payments-Signature header and exposes payment lifecycle events such as PaymentsInit, PaymentsWaitingConfirmations, and PaymentsReceived, including statuses like Paid and PartiallyPaid
    • The official signature-sdk-js README says the package creates digital signatures using RSA encryption and PEM encoding, returning a Base64 signature plus timestamp, which suggests INXY maintains explicit developer tooling around authenticated request flows
    • Together, the official site positioning plus the SDK footprint make INXY look like a crypto/stablecoin payment infrastructure vendor with both merchant-checkout and fintech-API ambitions
  • Whitepaper: No canonical standalone INXY Payments whitepaper or litepaper surfaced in this pass. The official site was only partially extractable, so the clearest source of truth was the company’s own site titles/snippets plus first-party GitHub SDK repositories and package documentation; see ../whitepapers/inxy-payments-primary-sources-2026-05-02.md.
