Introduction to OngsooLabs API

Welcome to the official documentation for public OngsooLabs API services.

OngsooLabs API focuses on practical data preparation tools for AI applications. The first public service, AI Reader API, helps developers turn web pages into clean Markdown, text, or structured JSON with usage, quality, and execution metadata for LLM, RAG, search, and summarization workflows.

What the Platform Provides

  • Content extraction: Identify the main readable content from a target web page.
  • AI-ready output: Return Markdown, text, or structured JSON through a stable content envelope.
  • Usage metadata: Return character count, token estimate, chunk count, and response credit metadata.
  • Quality signals: Return v0 quality signals and warnings without overclaiming a final quality score.
  • Execution metadata: Return runtime details such as execution profile, browser usage, cache status, retry count, and duration.
  • Output controls: Let callers choose whether optional items such as links, images, tables, or code blocks should be included.

Official Access Channels

AI Reader API is publicly available through two official access channels:

  • RapidAPI: Use the API key, host, subscription, request quota, and billing shown in your RapidAPI dashboard.
  • OngsooLabs.com: Use an OngsooLabs account, Direct API key, credits, and billing.

Both channels use the same core Reader execution and response contract. Accounts, authentication, API keys, subscriptions, quotas or credits, billing, and entitlements are managed independently and do not transfer between channels.

See the Reader sample, the official API guide, or OngsooLabs support for official service information.

Available APIs

  • AI Reader API: Fetches a web page, removes common boilerplate, and returns AI-ready content with standardized success and error responses.
  • Legal and Operational Policy: Defines caller responsibility, target-site limits, logging boundaries, cache policy, and abuse controls.

Usage Responsibility

Callers are responsible for complying with the terms of service, robots policies, copyright rules, and applicable laws for each target website they process.
