Square for payment gateways
As a payment gateway, Square is our fourth pick of four, and the rank fits its shape: Square is strongest for businesses that blend online and in-person commerce, less so as a pure online gateway. Its official server connects an agent to payments and orders through the full Square API, which makes it useful for reconciling point-of-sale activity against online charges.
Stripe, Adyen, and Razorpay rank ahead for gateway work because they lead on developer-first global processing, enterprise-scale acquiring, and regional specialization respectively. Square's place is the merchant who runs a physical and a digital channel and wants the agent to read across both.
How Square fits
The server exposes the Square API through get_service_info, which discovers a service's methods, get_type_info, which returns a method's parameter requirements, and make_api_request, which executes against the Square Connect API. For gateway questions an agent can look up a payment, trace the order behind it, and summarize activity across in-person and online, building each call from the discovery step rather than calling a named lookup tool.
The honest comparison: Stripe, the top pick, is the developer-first global processor with direct payment tooling; Adyen targets large-scale, multi-channel acquiring; and Razorpay specializes in its regional market. Square's strength is the blended commerce case, reconciling settlements that span a register and a website. Because its tools front the API generically, an agent does more call composition here than with a processor that ships dedicated payment verbs. Reach for Square when point-of-sale and online sit together; reach for a sibling when the priority is pure online gateway depth or a specific region. Treat payment data with care and record only what your policies allow.

FAQ
- Why is Square fourth among payment gateways?
- Square is strongest for blended online and in-person commerce, not as a pure online gateway. Stripe leads on developer-first global processing, Adyen on large-scale acquiring, and Razorpay on its region. Square's edge is reconciling point-of-sale against online activity.
- Can an agent investigate a payment through the Square server?
- Yes. get_service_info discovers the payment and order methods, get_type_info returns their parameters, and make_api_request runs the call against the Square Connect API, so an agent can look up a transaction and the order behind it. Handle payment data per your policies.
