Using Web Unlocker with AI Agents

How to use Gologin Web Unlocker as a scraping tool for AI agents and LLM pipelines

Gologin Web Unlocker is a scraping API that returns fully rendered HTML for any URL. For AI agents, this means reliable web access without browser orchestration — one HTTP call per page.

Don’t want to write code? Use the Web Access CLI or Scraping Skill to give your agent scraping capabilities out of the box.

Feed page content into an LLM

Scrape a page and pass the HTML to a model for extraction, summarization, or analysis — no parsing logic needed.

Python + Claude

import requests
import anthropic

html = requests.get(
    "https://parsing.webunlocker.gologin.com/v1/scrape",
    params={"url": "https://news.ycombinator.com"},
    headers={"apikey": "YOUR_API_KEY"}
).text

client = anthropic.Anthropic()
message = client.messages.create(
    model="claude-sonnet-4-5-20250514",
    max_tokens=1024,
    messages=[
        {
            "role": "user",
            "content": f"Extract the top 5 story titles and URLs from this HTML:\n\n{html[:8000]}"
        }
    ]
)

print(message.content[0].text)

JavaScript + Claude

import Anthropic from "@anthropic-ai/sdk";

const html = await fetch(
  "https://parsing.webunlocker.gologin.com/v1/scrape?url=" +
    encodeURIComponent("https://news.ycombinator.com"),
  { headers: { apikey: "YOUR_API_KEY" } }
).then((r) => r.text());

const client = new Anthropic();
const message = await client.messages.create({
  model: "claude-sonnet-4-5-20250514",
  max_tokens: 1024,
  messages: [
    {
      role: "user",
      content: `Extract the top 5 story titles and URLs from this HTML:\n\n${html.slice(0, 8000)}`,
    },
  ],
});

console.log(message.content[0].text);

Give your agent a scrape tool

Define a scrape tool backed by Web Unlocker. The agent decides when to fetch a page and what URL to scrape.

import requests
import anthropic

def scrape(url: str) -> str:
    """Fetch a URL and return its rendered HTML."""
    return requests.get(
        "https://parsing.webunlocker.gologin.com/v1/scrape",
        params={"url": url},
        headers={"apikey": "YOUR_API_KEY"}
    ).text

tools = [
    {
        "name": "scrape",
        "description": "Fetch the rendered HTML of any URL, including JavaScript-heavy and protected sites.",
        "input_schema": {
            "type": "object",
            "properties": {
                "url": {"type": "string", "description": "The URL to scrape"}
            },
            "required": ["url"]
        }
    }
]

client = anthropic.Anthropic()
messages = [
    {"role": "user", "content": "What is the current price of the iPhone 16 Pro on apple.com?"}
]

while True:
    response = client.messages.create(
        model="claude-sonnet-4-5-20250514",
        max_tokens=1024,
        tools=tools,
        messages=messages
    )

    if response.stop_reason == "end_turn":
        print(response.content[0].text)
        break

    tool_results = []
    for block in response.content:
        if block.type == "tool_use" and block.name == "scrape":
            html = scrape(block.input["url"])
            tool_results.append({
                "type": "tool_result",
                "tool_use_id": block.id,
                "content": html[:10000]
            })

    messages.append({"role": "assistant", "content": response.content})
    messages.append({"role": "user", "content": tool_results})

The agent decides when to scrape and what URL to fetch. Web Unlocker handles the retrieval — JavaScript rendering, anti-bot bypass, proxy rotation, CAPTCHA solving.

Use the Web Unlocker SDK

For TypeScript/Node.js agents, the gologin-webunlocker SDK provides typed methods:

import { WebUnlocker } from "gologin-webunlocker";

const client = new WebUnlocker({
  apiKey: process.env.GOLOGIN_WEBUNLOCKER_API_KEY!
});

// get structured metadata instead of raw HTML
const { data } = await client.scrapeJSON("https://example.com");
console.log(data.title, data.description, data.headings);

// get clean text for LLM context
const { text } = await client.scrapeText("https://example.com");

// batch scrape with concurrency control
const results = await client.batchScrape(
  ["https://example.com/1", "https://example.com/2", "https://example.com/3"],
  { concurrency: 3 }
);

See Web Unlocker SDK reference for all methods.

---

Use the CLI

For agents that call shell commands (like Claude Code), the CLI is the simplest path:

# plain text — good for LLM context
gologin-web-access scrape-text https://example.com

# structured JSON — title, description, headings, links
gologin-web-access scrape-json https://example.com

# batch scrape — many pages at once
gologin-web-access batch-scrape url1 url2 url3 --format text --summary

# search the web
gologin-web-access search "best antidetect browser 2026" --limit 10

# extract structured data with a schema
gologin-web-access extract https://example.com --schema ./schema.json

See Web Access CLI reference for all commands.

Common agent patterns

Pattern	How
Research agent	Agent calls scrape tool → reads pages → synthesizes findings
Price monitoring	batch-scrape product pages on schedule → compare with previous run
Competitive intelligence	crawl competitor sites → feed to LLM for analysis
Lead enrichment	scrape-json company pages → extract structured data
Content aggregation	search + scrape-text → build curated feeds
