Fintech
Fin (fin.tech) is a crypto-native payments company that lets users and businesses move millions of dollars instantly — to other Fin users, directly into bank accounts, or across crypto rails. It provides business-grade payment rails that feel like a consumer payment app rather than crypto: instant global settlement in seconds, native support to deposit and withdraw to bank accounts, and send/receive of USDT, USDC, ETH, and BTC, while Fin abstracts the underlying crypto settlement behind a clean fintech interface. Backed by Sequoia, Multicoin, and Pantera Capital, Fin operates a private, auth-gated production API surface (api.fin.tech) and publishes an llms.txt for agents; it does not currently publish a public developer portal, OpenAPI, or SDKs. Surfaced in the API Evangelist network as a Pantera Capital portfolio company (sector: crypto) and enriched from its public web surface.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Fintech the way a machine reads it — 1 machine-readable artifact, 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 — Fintech scores 13.9/100 (minimal), with a separate agent-readiness read of 0/100 (human only). 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.

How we profile Fintech
Each block below is one kind of artifact we hold for Fintech. 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.
Security Posture 1
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.
