Switstack
Switstack is a payment infrastructure company building software-defined EMV acceptance for physical retail. It ships three products: switstack moka, a source-available EMV Level 2 kernel stack with brand Letters of Compliance; Switcloud, a hosted "universal compliance infrastructure" that abstracts EMV L2 execution and centralizes estate (organization/merchant/store/POI) and EMV configuration (CAPK, BIN, CRL, kernel parameter) management behind a REST API; and Swittest, a managed EMV functional test-automation service for labs and developers certifying card-present applications. The platform is terminal-agnostic and L2-stack agnostic — one L3 application runs across Android COTS tap-to-pay devices and PCI-PTS terminals via a GLA adapter layer — and Switstack supplies pre-certified PCI MPoC software and service components to shrink certification scope.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Switstack the way a machine reads it — 17 machine-readable artifacts across 4 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Switstack scores 39.4/100 (developing), with a separate agent-readiness read of 28/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Switstack
Each block below is one kind of artifact we hold for Switstack. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 8
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Switstack Auth API
The Auth API from Switstack — 3 operation(s) for auth.
Switstack BOM API
The BOM API from Switstack — 6 operation(s) for bom.
Switstack Config API
The Config API from Switstack — 29 operation(s) for config.
Switstack Parser API
The Parser API from Switstack — 4 operation(s) for parser.
Switstack Payment API
The Payment API from Switstack — 4 operation(s) for payment.
Switstack Suite API
The Suite API from Switstack — 2 operation(s) for suite.
Switstack Test API
The Test API from Switstack — 5 operation(s) for test.
Switstack Validation API
The Validation API from Switstack — 6 operation(s) for validation.

Arazzo Workflows 3
Real integrations are rarely a single call. Arazzo describes the multi-step sequences — auth, then create, then confirm — so both a human and an agent can follow the choreography, not just the endpoints.
Multi-step API workflows described with the Arazzo specification.
Onboard a Switcloud terminal
Authenticate, build the Merchant -> Store -> POI estate, assemble a minimum EMV configuration, and bundle it into the POIConfig a terminal fetches at runtime. This is steps 1 an...

ARAZZOPricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.
Switstack Rate Limits
RATE LIMITSSecurity Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Scopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.
OAuth scopes governing access to this provider's APIs.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.

This is an independent, third-party profile of Switstack, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
