The Missing Layer in Agentic AI — Giedrius Šteimantas, Oxylabs
The video addresses a critical gap in agentic AI: the lack of robust infrastructure for interacting with the open web. The speaker argues that relying solely on large language models (LLMs) or general browser automation is inefficient, expensive, and unreliable. By applying principles from professional web scraping—specifically prioritizing cost control, validating content before processing, and using a browser only when absolutely necessary—the agent's performance can be dramatically improved across all stages of the purchase workflow.

The Core Problem in Agentic AI
13:55
Many agents fail or waste resources because they assume an HTTP 200 status code means valid content. Feeding LLMs large HTML blocks containing CAPTCHAs or non-product data leads to wasted tokens (e.g., wasting 70% of tokens when only three out of ten pages are valid).

Discovery Stage Optimization
9:50
Instead of using a browser with a predefined list of retailers, the agent should use a dedicated search API. This approach returns compact JSON (<2,000 tokens), is fast (<700ms), and allows the agent to fan out queries across many popular search engines.
-
Decision Stage Optimization
The decision stage can be optimized by replacing browser scraping with a dedicated scraper API. This ensures only valid content is returned, fails loudly (with explicit errors on blocks), supports markdown, and allows parallel requests while billing only for successful results ('No cure, no pay').

Checkout Stage Enhancement
Since the checkout process requires highly dynamic interaction, a browser is necessary. The solution involves hardening the agent using Playwright MCP combined with an Oxylabs headless browser that provides stealth, residential proxy support, and geolocation capabilities.
