MadKudu
MadKudu is a predictive lead scoring and account intelligence platform for B2B sales and marketing teams, using AI-driven propensity modeling and dynamic scoring across fit, intent, and engagement signals to surface high-propensity accounts and people. Its developer surface (MadAPI) programmatically exposes account and person lookup, enrichment, activity, search, sourcing discovery, AI web search, organisation endpoints and a "coming soon" custom ingestion API, alongside a legacy Scoring API and a hosted Model Context Protocol (MCP) server for AI agents. MadKudu publishes OpenAPI 3.1.0 for both surfaces, but only as per-operation blocks embedded in its GitBook reference — no spec document is served. MadKudu was acquired by HG Insights in 2025; the docs are now titled "HG Platform API" and API access is contact-sales. Originally backed by Partech and Techstars.
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 MadKudu the way a machine reads it — 18 machine-readable artifacts across 2 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 — MadKudu scores 51.2/100 (developing), with a separate agent-readiness read of 36/100 (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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile MadKudu
Each block below is one kind of artifact we hold for MadKudu. 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 12
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.
MadKudu Accounts API
The Accounts API from MadKudu — 3 operation(s) for accounts.
MadKudu AI API
The AI API from MadKudu — 1 operation(s) for ai.
MadKudu Companies API
The Companies API from MadKudu — 1 operation(s) for companies.
MadKudu Enrichment API
The Enrichment API from MadKudu — 1 operation(s) for enrichment.
MadKudu Ingestion API
The Ingestion API from MadKudu — 3 operation(s) for ingestion.
MadKudu Job Changes API
The Job Changes API from MadKudu — 1 operation(s) for job changes.
MadKudu Lookup API
The Lookup API from MadKudu — 2 operation(s) for lookup.
MadKudu Organisation API
The Organisation API from MadKudu — 2 operation(s) for organisation.
MadKudu Persons API
The Persons API from MadKudu — 3 operation(s) for persons.
MadKudu Search API

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 SERVERPricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.

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.

This is an independent, third-party profile of MadKudu, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
