Hello GPT-4o

openai.com/index/hello-gpt-4o

GPT-4o (“o” for “omni”) is a step towards much more natural human-computer interaction — it accepts as input any combination of text, audio, image, and video and generates any combination of text, audio, and image outputs.

Key Capabilities

  • - Text, audio, and image input and output
  • - 50% cheaper than GPT-4 Turbo in the API
  • - 2x faster with 5x higher rate limits

How link.sc works

Three steps to go from a raw URL to clean, LLM-ready context.

01

Send a Request

Call our API with a URL or search query. Use our Python SDK, Node.js library, or plain cURL.

02

We Handle the Hard Parts

Our engine renders JavaScript, rotates proxies, solves CAPTCHAs, and bypasses anti-bot systems automatically.

03

Get Clean Data Back

Receive structured Markdown, JSON, or screenshots optimized for LLM token efficiency and RAG pipelines.

Everything you need to turn
websites into AI-ready data.

Two powerful APIs. One platform. Built for developers and AI teams who need reliable, clean data at scale.

Core

Fetch

Convert any URL into clean Markdown, structured JSON, or screenshots. Our engine strips ads, navigation, popups, and boilerplate — leaving only the content your LLM needs.

Built for the hardest
web data challenges

We handle the complexity of the modern web so you can focus on building your AI application.

Anti-Bot Bypass

Automatically handle Cloudflare, Akamai, DataDome, PerimeterX, and hCaptcha with 99.2% success rate.

Residential Proxies

Rotate through millions of residential IPs across 195 countries. Geo-target any region for localized content.

JS Rendering

Full headless browser rendering for React, Next.js, Vue, Angular, and any JavaScript-heavy SPA.

Smart Wait

Automatically detect when dynamic content has finished loading. No manual wait timers needed.

Interactive Actions

Click buttons, scroll pages, fill forms, and dismiss popups before extraction for gated content.

Media Parsing

Extract text from PDFs, DOCX files, and images hosted on the web alongside standard HTML pages.

Screenshot Capture

Full-page or viewport screenshots in PNG or JPEG format. Perfect for visual verification and archiving.

Rate Limit Handling

Automatic retry with exponential backoff. We respect robots.txt and adjust request speed to avoid blocks.

Selective Caching

Built-in response caching with configurable TTL. Reduce costs and latency for frequently accessed pages.

Built for modern AI workflows

From RAG pipelines to autonomous agents, link.sc powers the data layer for thousands of AI applications.

RAG Pipelines

Feed your retrieval-augmented generation pipeline with clean, chunking-ready Markdown. Preserve semantic structure while eliminating noise that degrades retrieval quality.

Loved by developers

Here's what teams are saying about link.sc.

We replaced 2,000 lines of Puppeteer code with 5 lines of link.sc fetch calls. Our RAG pipeline went from 60% to 94% retrieval accuracy overnight.

Sarah Chen

ML Engineer, NeuralPath

The search API is a game-changer for our AI agents. Real-time web data grounding reduced hallucinations by over 40% in production.

Marcus Rivera

CTO, AgenticHQ

We evaluated every web data API on the market. Link.sc was the only one that returned Markdown clean enough to feed directly into our embedding pipeline.
