The most accurate Content Classification API. Categorize websites into 385+ topic categories with confidence scores, extract logos, social media links, company information, and technology stack data. On Nagent, Klazify is exposed as a fully-configurable developer tools integration that any agent can call — 8 actions, and API key authentication. No code is required to wire Klazify into your workflow — connect it once via the External Integrations panel and reuse it across every agent you build.
Agent builders use Klazify to automate the kinds of tasks developer tools teams previously handled manually. Concrete examples — each one is a single agent step in Nagent — include:
Every action and trigger is paired with a structured input/output schema (visible in the sections below), so when you wire Klazify into Helix — our agentic agent builder — the editor knows exactly what each step expects and produces. Configure once, deploy anywhere across your Nagent agents.
Every operation an agent can call against Klazify, with input parameters and output schema. Drop these into any step of an agent built in Helix.

No publicly available marketplace agent is found using this tool yet. There are 56 agents privately built on Nagent that already use Klazify.
Build on Nagent
Connect Klazify to any Nagent agent in minutes — no API key management, no boilerplate. Just configure and deploy.
The five questions agent builders ask before adopting a new integration.
Open the External Integrations panel inside Nagent (app.nagent.ai/externalIntegration), find Klazify, and click "Connect Now." You'll authenticate with an API key — Nagent handles credential storage and refresh automatically. Once connected, Klazify is available to any agent in your workspace.
No. Nagent provides no-code integration for every tool. Once Klazify is connected, you configure its 8 actions directly in the agent builder UI — no API calls, no boilerplate, no schema management.
Helix — Nagent's agentic agent builder — lets you drop Klazify steps into any workflow visually. Pick an action (e.g., one of those listed above), fill in the inputs (Helix knows the required vs. optional schema for each parameter), and connect it to upstream/downstream steps. Triggers run as the entry point of an agent, so when a Klazify event fires, the agent kicks off automatically.
Every Klazify action and trigger ships with a fully-typed schema — input parameters with name, type, required flag, and description, plus the output payload shape. The schemas are documented in the sections above. Helix uses these schemas to validate your configuration at build time and to type-check the data flowing between steps.
Yes. While Klazify ships with 8 pre-built developer tools actions, you can layer custom logic around them inside Helix — pre/post-processing steps, conditional branches, retries, or stitching Klazify together with other connected tools.
