MadKudu

aid: madkudu
name: MadKudu
description: 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.

- name: MadKudu API (MadAPI)
  description: The current MadKudu API (MadAPI) exposes account and person lookup, full account/person details and activities,
    company hiring/job-posting enrichment, advanced account and person search, prospect discovery and contact enrichment through
    connected sourcing providers (Apollo, Cognism, ZoomInfo), Tavily-backed AI web search, tenant organisation/value-prop
    endpoints, and a custom ingestion API documented as "Coming Soon" — 19 operations in all. Authentication is a raw API
    key in the x-api-key header; billing is credit-metered per call (HTTP 429 on exhaustion) with no rate-limit response headers.

- name: MadKudu Legacy Scoring API
  description: The legacy MadKudu Scoring API returns customer-fit (demographics), likelihood-to-buy and lead-grade scores
    for companies by domain and persons by email, plus a job-changes watch list and a ping utility — 6 operations. Authentication
    is HTTP Basic (API key as username, empty password) with a different key from MadAPI; rate limited to 600 requests per
    endpoint per minute (HTTP 429 when exceeded). MadKudu labels this surface "Legacy" and steers new integrations to MadAPI,
    but publishes no dated deprecation or sunset policy.
