Browser-Based Flight Search

USE BROWSER ONLY WHEN:

User specifically asks to check Google Flights / Kayak / Skyscanner
API search returned no results and user wants broader coverage
Price comparison requested against external sources

Browser Commands (OpenClaw Playwright-on-CDP with ARIA Snapshots)

browser snapshot — get ARIA tree with [ref=eN] element references
browser type [ref=eN] "value" — type into an input field
browser click [ref=eN] — click an element
browser screenshot — capture current page state

Google Flights

Navigate to https://www.google.com/travel/flights
browser snapshot → ARIA tree
Fill origin, destination, dates using [ref] locators
Click search, wait 5s for results
browser snapshot → extract airlines, prices, durations, stops
Enrich with jetlag scores via POST /api/v1/flights/score before presenting

Kayak

Navigate to https://www.kayak.com
Same snapshot → fill → search → extract pattern

Skyscanner

Navigate to https://www.skyscanner.com
Same snapshot → fill → search → extract pattern

Always

Present browser results as "comparison data" — recommend booking through our API
Random delays (3-8s) between browser actions
Max 10 browser searches per day per user
Enrich all results with jetlag scores before presenting to user

Rate Limits

Max 10 browser flight searches per day per user.
Back off 24 hours if any site blocks the browser.

Rate Limit Tracking

Track all browser searches in workspace file ~/browser-searches.json:

{
  "date": "2026-02-22",
  "count": 3,
  "searches": [
    { "site": "google-flights", "query": "JFK-NRT 2026-03-15", "timestamp": "2026-02-22T10:30:00Z" }
  ],
  "blockedUntil": null
}

Before each browser search:

Read ~/browser-searches.json (create if missing)
If date differs from today, reset count to 0 and clear searches
If blockedUntil is set and in the future, refuse — tell user blocked by site
If count >= 10, refuse — tell user daily browser search limit reached
After each search, increment count and append to searches
If a site blocks the browser, set blockedUntil to 24 hours from now

Browser Best Practices

Context Selection

DIRECT (no proxy): Google Flights, Kayak, Booking.com, Google Hotels, Lufthansa SCRAPLING (stealth service, no proxy needed): Delta, British Airways, SecretFlying, seats.aero, Southwest, Hilton, Hyatt, TripAdvisor, TheFlightDeal, Going, SeatGuru, Google Travel (flights + hotels) PROXY (residential): United, American Airlines, Air Canada, KLM, TravelPirates SKIP BROWSER (use API):

Hotel search → LiteAPI first, browser for enrichment only
Deal discovery → Aerobase Deals API first, browser for verification only
Tours/activities → Aerobase Tours API first, browser rarely needed
Flight pricing → Amadeus/Kiwi API, browser for visual comparison
Award search → seats.aero API, browser for airline-specific lookups

Scrapling Service (Anti-Bot Bypass)

When browser automation is blocked by anti-bot systems (Akamai, Cloudflare, Datadome, etc.), use the stealth scrapling service configured via SCRAPLING_URL environment variable. This service bypasses detection WITHOUT needing residential proxies.

Reference: Scrapling Documentation

When to use Scrapling:

Site shows reCAPTCHA, "Access denied", or challenge page
Normal browser is blocked or redirected
Need to extract data from JS-heavy sites

How to invoke:

Fetch a page (returns JSON with status, title, HTML, challenge detection):

web_fetch {SCRAPLING_URL}/fetch?url=https://www.delta.com&json=1

Run JavaScript on a page:

POST {SCRAPLING_URL}/evaluate
Body: {"url": "https://seats.aero", "script": "document.title"}

Check service health:

web_fetch {SCRAPLING_URL}/health

Response fields:

status: HTTP status code (200 = success)
title: Page title
challenge: "pass" | "captcha" | "blocked" | "challenge"
cached: true if served from 5-min cache
html: Page HTML (truncated to 50KB in JSON mode)
html_length: Full HTML length

Fallback chain:

Try Scrapling service first for listed domains
If challenge != "pass": fall back to native browser + residential proxy
If proxy also fails: screenshot and tell user

Important: Scrapling responses are cached for 5 minutes. For time-sensitive data (live prices, seat maps), append &nocache=1 or wait for cache expiry.

Aggregator Search (Scrapling /search)

Pre-built search + Python-side parsing. Returns structured JSON — no browser snapshot/type/click needed. Results are parsed server-side via Scrapling's Adaptor engine (CSS selectors, find_similar for self-healing).

Google Flights:

POST {SCRAPLING_URL}/search
{"site":"google-flights","origin":"LAX","destination":"NRT","departure":"2026-03-15","return":"2026-03-22"}

Returns: {"results": [{"airline":"...","price":"...","duration":"...","stops":"..."}], "count": N}

Kayak:

POST {SCRAPLING_URL}/search
{"site":"kayak","origin":"LAX","destination":"NRT","departure":"2026-03-15","return":"2026-03-22"}

Booking.com hotels:

POST {SCRAPLING_URL}/search
{"site":"booking","destination":"Tokyo","checkin":"2026-03-15","checkout":"2026-03-22","guests":2}

Returns: {"results": [{"name":"...","price":"...","rating":"...","location":"..."}], "count": N}

Deal sites:

POST {SCRAPLING_URL}/search
{"site":"secretflying"}
POST {SCRAPLING_URL}/search
{"site":"theflightdeal"}

Returns: {"results": [{"title":"...","url":"..."}], "count": N}

Check challenge field — if not "pass", results may be incomplete (consent wall, bot block).

Multi-Step Interaction (Scrapling /interact)

For flows needing form fill, click, screenshot (check-in, login, registration):

POST {SCRAPLING_URL}/interact
{
  "url": "https://www.southwest.com/air/check-in/",
  "steps": [
    {"action": "consent"},
    {"action": "fill", "selector": "#confirmationNumber", "value": "ABC123"},
    {"action": "fill", "selector": "#firstName", "value": "John"},
    {"action": "fill", "selector": "#lastName", "value": "Doe"},
    {"action": "click", "selector": "button#form-mixin--submit-button"},
    {"action": "wait", "ms": 5000},
    {"action": "screenshot"},
    {"action": "extract", "css": "h1::text"}
  ]
}

Available actions:

consent — auto-dismiss cookie consent walls
fill — fill input by CSS selector (instant, like paste)
type — type with per-key delay (more human-like, use for sensitive fields)
click — click element by CSS selector
wait — wait N milliseconds
wait_for — wait for selector to appear (with timeout)
screenshot — capture current page (returned as base64 in screenshots array)
extract — parse page with CSS selector (results in extracted array)
select — select dropdown option

Fetch with Screenshot or CSS Extraction

web_fetch {SCRAPLING_URL}/fetch?url=https://www.delta.com&json=1&screenshot=1
web_fetch {SCRAPLING_URL}/fetch?url=https://www.secretflying.com&json=1&extract=css&selector=article

Search + Book Pattern

Fire API search (Kiwi/Duffel) immediately — don't wait for browser
Fire Scrapling /search in parallel for comparison data
Show API results first (faster, <2s)
Merge Scrapling results: "Google Flights also shows..." / "Kayak prices..."
For booking: use API (Duffel hold → user confirms → API completes)
For airline-direct booking: navigate user to airline site via VNC
NEVER automate payment card entry via browser

Booking Flow

API booking (Duffel/Kiwi): Agent can search, hold, and complete with user approval
Browser booking: Navigate to site, user completes payment via VNC
NEVER automate payment card entry via browser (PCI compliance, 3D Secure blocks)
For held bookings: confirm with user before paying (Duffel supports 24-72h holds)

API-First + Browser-Concurrent Pattern

For any task where we have an API:

Fire API request immediately (don't wait for browser)
Show API results to user as they arrive
Launch browser concurrently if enrichment would help
Merge browser findings: "I also found..." / "For comparison..."
Highlight discrepancies between API and browser data This gives the user instant results + richer context seconds later.

Launch Checklist

Stealth plugin is auto-loaded — no action needed
Choose direct or proxy context based on target domain
Set viewport 1440x900, locale en-US, timezone America/New_York
Set 30s default timeout for navigation
ALWAYS register error handler: page.on('pageerror', ...)

Memory Management (CRITICAL)

Chrome watchdog kills process at 1800MB RSS
Max 2 concurrent tabs safely (tested: 3 tabs = 1795MB = danger zone)
ALWAYS close context after task: await context.close()
Prefer sequential tabs over concurrent
If opening multiple tabs: close each before opening next
Monitor with: process.memoryUsage().rss

Cookie Consent (EU server — Helsinki)

Scrapling service handles consent dismissal automatically via page_action. For native browser, patterns to try in order:

button:has-text("Reject all")
button:has-text("Decline")
button:has-text("Alle ablehnen")
button:has-text("I decline")
[data-testid="reject-button"]
button:has-text("Manage") → then "Reject all" in second dialog Timeout: 5s for consent dialog, then proceed (some sites don't show it)

Bot Detection Response

If you see any of these, you're being blocked:

reCAPTCHA iframe or badge
"Please verify you are a human"
"Access denied" / "403 Forbidden"
Datadome challenge page
Blank page with Cloudflare "checking your browser"
"Pardon our interruption" (Akamai)

Response:

If domain is in Scrapling list: try Scrapling service first (no proxy cost)
If Scrapling returns challenge != "pass": fall back to native browser + PROXY
If on DIRECT: retry with PROXY context
If already on PROXY: screenshot and fallback to alternative site
Tell user: "I'm seeing a verification on [site]. Let me try [alternative]."
NEVER attempt to solve CAPTCHAs
Max 2 retries per site per session

Screenshot Best Practices

Full page: page.screenshot({ fullPage: true }) — use for results
Viewport only: page.screenshot() — use for errors/blocks
Element: element.screenshot() — use for specific data extraction
Always save to /tmp/ with descriptive name
Offer to show screenshots to user when relevant

Geo-Awareness

Server is in Helsinki, Finland (EU). This means:

Airline sites redirect to EU versions (/eu/en, .de, etc.)
Prices show in EUR by default on many sites
Cookie consent walls appear on almost every site
Some US-only features/deals may not be accessible
With US residential proxy: sites see US IP, show USD, US content

Performance Targets

Page load: <10s acceptable, <5s ideal
Search results: <15s acceptable
Check-in form: <10s
If exceeding 30s: abort, screenshot, try alternative
