Unstoppable Finance (Iron)
Unstoppable Finance is the Berlin fintech behind Iron (iron.xyz), the Stablecoin Payment Network - fiat-to-stablecoin and stablecoin-to-fiat infrastructure for businesses. Founded as Unstoppable Finance GmbH and builder of the Ultimate self-custodial DeFi wallet, the company rebranded to Iron and was acquired by MoonPay in 2025. The Iron API provides onramp, offramp, and swap flows via Autoramps (standing fiat/crypto conversion rules), customer onboarding with tiered KYC/KYB, Travel Rule wallet verification, virtual accounts, fee profiles, exchange rates, stablecoin issuance, and Standard Webhooks event delivery, with a fully simulated sandbox environment.
Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.
API Evangelist profiles Unstoppable Finance (Iron) the way a machine reads it — 15 machine-readable artifacts across 9 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 — Unstoppable Finance (Iron) scores 60.8/100 (strong), with a separate agent-readiness read of 69/100 (agent native). 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.

Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.
