Kanastra
Kanastra is a Brazilian fintech building full-stack infrastructure for banking and the private credit market. Its Banking API offers banking-as-a-service capabilities to financial institutions, funds and securitization vehicles: financial (checking) accounts with balances and transactions, PIX (key registration, transfers, deposits, and static/dynamic QR Codes on the BR Code / EMV-QRCPS standard), boleto (bank slip) issuance with CNAB return-file processing settled via the Nuclea clearing house, TED transfers, wallets, commercial notes (CCB) with guarantees and documents, and issuers. Authentication uses a private_key_jwt (ES512 client-assertion) flow that returns a scoped Bearer JWT, and a webhook surface streams bank slip and CNAB lifecycle events. Kanastra is backed by QED Investors, Kaszek, Valor Capital, Quona Capital, Itau, IFC and F-Prime.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Kanastra the way a machine reads it — 25 machine-readable artifacts across 20 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 — Kanastra scores 35.2/100 (thin), with a separate agent-readiness read of 33/100 (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.

A runnable collection turns the contract into something a developer can execute in seconds. We profile them because the fastest way to trust an API is to make a real call against it.

POSTMANEvent 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.
