Datanomik
Datanomik is a Brazilian open finance and treasury-management platform that gives mid-to-large enterprises real-time, consolidated visibility across their bank accounts, balances, investments and payments through a single API. Authorized by Banco Central do Brasil as a Payment Transaction Initiator (ITP) and a participant in Brazil's Open Finance ecosystem, Datanomik connects to 30+ Brazilian financial institutions (Banco do Brasil, Itau, Bradesco, Caixa, BTG, Nubank, Safra, Mercado Pago and others) to deliver bank connectivity, cash and liquidity management, investment-portfolio tracking, cash-flow forecasting, cash pooling and transfers, automated bank statements and financial reporting. The company exposes two REST APIs - an OpenBanking data API and a Treasury/Remuneration API - secured with HTTP Basic API keys, documented on a ReadMe developer portal with a public Postman workspace and a dedicated sandbox. Backed by a16z, its clients include iFood, Magalu, Flamengo and Unimed.
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 Datanomik the way a machine reads it — 14 machine-readable artifacts across 10 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 — Datanomik scores 52.8/100 (developing), 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.

How we profile Datanomik
Each block below is one kind of artifact we hold for Datanomik. 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 10
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.

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 SERVERSecurity 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.
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.
