CLI Setup Reference

Install, authentication, and troubleshooting for the Bright Data CLI (bdata) are documented in a single canonical place:

→ references/cli-setup.md

Consult it before any task that shells out to bdata.

Bright Data APIs

Bright Data provides infrastructure for web data extraction at scale. Four primary APIs cover different use cases — always pick the most specific tool for the job.

Choosing the Right API

Use Case	API	Why
Scrape any webpage by URL (no interaction)	Web Unlocker	HTTP-based, auto-bypasses bot detection, cheapest
Google / Bing / Yandex search results	SERP API	Specialized for SERP extraction, returns structured data
Structured data from Amazon, LinkedIn, Instagram, TikTok, etc.	Web Scraper API	Pre-built scrapers, no parsing needed
Click, scroll, fill forms, run JS, intercept XHR	Browser API	Full browser automation
Puppeteer / Playwright / Selenium automation	Browser API	Connects via CDP/WebDriver
Route your own HTTP client through a raw proxy (DC/ISP/Residential/Mobile)	Proxy networks	When you need direct proxy access with your own request logic instead of a managed API — see the `proxy.md` skill

Authentication Pattern (All APIs)

All APIs share the same authentication model. The env vars below apply to direct REST API integrations — if you are using the bdata CLI, bdata login handles all of these automatically (see references/cli-setup.md).

export BRIGHTDATA_API_KEY="your-api-key"         # From Control Panel > Account Settings
export BRIGHTDATA_UNLOCKER_ZONE="zone-name"       # Web Unlocker zone name
export BRIGHTDATA_SERP_ZONE="serp-zone-name"      # SERP API zone name
export BROWSER_AUTH="brd-customer-ID-zone-NAME:PASSWORD"  # Browser API credentials

REST API authentication header for Web Unlocker and SERP API:

Authorization: Bearer YOUR_API_KEY

Web Unlocker API

HTTP-based scraping proxy. Best for simple page fetches without browser interaction.

Endpoint: POST https://api.brightdata.com/request

import requests
 
response = requests.post(
    "https://api.brightdata.com/request",
    headers={"Authorization": f"Bearer {API_KEY}"},
    json={
        "zone": "YOUR_ZONE_NAME",
        "url": "https://example.com/product/123",
        "format": "raw"
    }
)
html = response.text

Key Parameters

Parameter	Type	Description
`zone`	string	Zone name (required)
`url`	string	Target URL with `http://` or `https://` (required)
`format`	string	`"raw"` (HTML) or `"json"` (structured wrapper) (required)
`method`	string	HTTP verb, default `"GET"`
`country`	string	2-letter ISO for geo-targeting (e.g., `"us"`, `"de"`)
`data_format`	string	Transform: `"markdown"` or `"screenshot"`
`async`	boolean	`true` for async mode

Quick Patterns

# Get markdown (best for LLM input)
response = requests.post(
    "https://api.brightdata.com/request",
    headers={"Authorization": f"Bearer {API_KEY}"},
    json={"zone": ZONE, "url": url, "format": "raw", "data_format": "markdown"}
)
 
# Geo-targeted request
json={"zone": ZONE, "url": url, "format": "raw", "country": "de"}
 
# Screenshot for debugging
json={"zone": ZONE, "url": url, "format": "raw", "data_format": "screenshot"}
 
# Async for bulk processing
json={"zone": ZONE, "url": url, "format": "raw", "async": True}

Critical rule: Never use Web Unlocker with Puppeteer, Playwright, Selenium, or anti-detect browsers. Use Browser API instead.

See references/web-unlocker.md for complete reference including proxy interface, special headers, async flow, features, and billing.

SERP API

Structured search engine result extraction for Google, Bing, Yandex, DuckDuckGo.

Endpoint: POST https://api.brightdata.com/request (same as Web Unlocker)

    "https://api.brightdata.com/request",
    headers={"Authorization": f"Bearer {API_KEY}"},
    json={
        "zone": "YOUR_SERP_ZONE",
        "url": "https://www.google.com/search?q=python+web+scraping&brd_json=1&gl=us&hl=en",
        "format": "raw"
    }
)
data = response.json()
for result in data.get("organic", []):
    print(result["rank"], result["title"], result["link"])

Essential Google URL Parameters

Browser API (Scraping Browser)

Full browser automation via CDP/WebDriver. Handles CAPTCHA, fingerprinting, and anti-bot detection automatically.

Connection:

Playwright/Puppeteer: wss://${AUTH}@brd.superproxy.io:9222
Selenium: https://${AUTH}@brd.superproxy.io:9515

const { chromium } = require("playwright-core");
 
const AUTH = process.env.BROWSER_AUTH;
const browser = await chromium.connectOverCDP(`wss://${AUTH}@brd.superproxy.io:9222`);
const page = await browser.newPage();
page.setDefaultNavigationTimeout(120000); // Always set to 2 minutes
 
await page.goto("https://example.com", { waitUntil: "domcontentloaded" });
const html = await page.content();
await browser.close();

from playwright.async_api import async_playwright
 
async with async_playwright() as p:
    browser = await p.chromium.connect_over_cdp(f"wss://{AUTH}@brd.superproxy.io:9222")
    page = await browser.new_page()
    page.set_default_navigation_timeout(120000)
    await page.goto("https://example.com", wait_until="domcontentloaded")
    html = await page.content()
    await browser.close()

Custom CDP Functions

Function	Purpose
`Captcha.solve`	Manually trigger CAPTCHA solving
`Captcha.setAutoSolve`	Enable/disable auto CAPTCHA solving
`Proxy.setLocation`	Set precise geo location (call BEFORE goto)
`Proxy.useSession`	Maintain same IP across sessions
`Emulation.setDevice`	Apply device profile (iPhone 14, etc.)
`Emulation.getSupportedDevices`	List available device profiles
`Unblocker.enableAdBlock`	Block ads to save bandwidth
`Unblocker.disableAdBlock`	Re-enable ads
`Input.type`	Fast text input for bulk form filling
`Browser.addCertificate`	Install client SSL cert for session
`Page.inspect`	Get DevTools debug URL for live session

// CDP session pattern for custom functions
const client = await page.target().createCDPSession();
 
// CAPTCHA solve with timeout
const result = await client.send("Captcha.solve", { timeout: 30000 });
 
// Precise geo location (must be before goto)
await client.send("Proxy.setLocation", {
  latitude: 37.7749,
  longitude: -122.4194,
  distance: 10,
  strict: true
});
 
// Block unnecessary resources
await client.send("Network.setBlockedURLs", { urls: ["*google-analytics*", "*.ads.*"] });
 
// Device emulation
await client.send("Emulation.setDevice", { deviceName: "iPhone 14" });

Session Rules

One initial navigation per session — new URL = new session
Idle timeout: 5 minutes
Max duration: 30 minutes

Geolocation

Country-level: append -country-us to credentials username
EU-wide: append -country-eu (routes through 29+ European countries)
Precise: use Proxy.setLocation CDP command (before navigation)

Error Codes

Code	Issue	Fix
`407`	Wrong port	Playwright/Puppeteer → `9222`, Selenium → `9515`
`403`	Bad auth	Check credentials format and zone type
`503`	Service scaling	Wait 1 minute, reconnect

Billing: Traffic-based only. Block images/CSS/fonts to reduce costs.

See references/browser-api.md for complete reference including all CDP functions, bandwidth optimization, CAPTCHA patterns, and debugging.

brightdata-proxy — For routing requests through Bright Data's raw proxy networks (Datacenter, ISP, Residential, Mobile) with your own HTTP client instead of a managed API. Covers network/IP-pool selection, the brd-customer-... username format, targeting & sticky-session params, SSL CA setup for Residential/Mobile, and integrations for cURL, Python (requests/httpx/aiohttp/Scrapy), Node (fetch/axios), Playwright, Puppeteer, and Selenium. Hand off to it whenever the task is raw proxy access rather than Web Unlocker / SERP / Web Scraper / Browser API. Escalation order when proxies hit consistent blocks: raw proxy → Web Unlocker → Browser API → Web Scraper API.

brightdata-proxy — For routing requests through Bright Data's raw proxy networks (Datacenter, ISP, Residential, Mobile) with your own HTTP client instead of a managed API. Covers network/IP-pool selection, the brd-customer-... username format, targeting & sticky-session params, SSL CA setup for Residential/Mobile, and integrations for cURL, Python (requests/httpx/aiohttp/Scrapy), Node (fetch/axios), Playwright, Puppeteer, and Selenium. Hand off to it whenever the task is raw proxy access rather than Web Unlocker / SERP / Web Scraper / Browser API. Escalation order when proxies hit consistent blocks: raw proxy → Web Unlocker → Browser API → Web Scraper API.
