alt.bank

alt.bank is a Brazilian fintech offering a turnkey credit-card platform that lets partners launch their own prepaid and postpaid credit cards in Brazil without holding a banking license. The company provides white-label card issuance, Visa BIN sponsorship, digital onboarding with KYC/AML, and fraud/chargeback management. Its developer surface centers on GUARD, a credit-underwriting and risk-scoring API that scores applicants (by CPF) against traditional and alternative data and returns a risk band and a suggested initial credit line asynchronously via partner callback, alongside the CLIMB limit-management system and the Pix Crédito product. Founded in 2018 and backed by Union Square Ventures, Anthemis, and others, alt.bank targets the underbanked across Brazil and Latin America.

agent ready

Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.

Kin Score

API Evangelist profiles alt.bank the way a machine reads it — 5 machine-readable artifacts across 1 API, 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 — alt.bank scores 36.9/100 (thin), with a separate agent-readiness read of 49/100 (agent ready). 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 alt.bank

Each block below is one kind of artifact we hold for alt.bank. 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 1

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.

alt.bank Underwriting API

Credit underwriting and risk scoring for partner card issuance.

MCP Servers 1

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

MCP SERVER

Event Specifications 1

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.

AsyncAPI definitions for this provider's event-driven and streaming APIs.

Security 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.
