Waterfall & Vision Sourcing

Once a product passes the M4 Acceleration Engine, OBrain triggers the Waterfall Sourcing Pipeline to discover the most profitable arbitrage gap across multiple international supply chains.

Tiered Fallback Mechanism

We utilize a robust fallback architecture to guarantee product matches regardless of the API availability.

1. CJ Dropshipping (Primary): Clean API, fast fulfillment, primarily used for B2C rapid testing.
2. AliExpress Scraper (Secondary): Used when CJ lacks catalog depth. Provides a vast array of consumer-grade electronics and accessories.
3. 1688 VLM (Tertiary/Alpha): The ultimate B2B factory discovery engine. Bypasses standard rate-limiting and layout obfuscation by "looking" at the screen.

Visual Language Model (VLM) Implementation

When 1688 obfuscates its HTML or blocks standard scrapers, OBrain activates Llama-3.2 Vision.

Instead of parsing fragile DOM elements, the system takes a screenshot via Playwright and passes it to the VLM:

def extract_factory_price(image_path: str) -> float:
    prompt = "Extract the lowest bulk price (in RMB) from this 1688 product page screenshot. Return ONLY the float number."
    response = vlm_engine.generate(image=image_path, prompt=prompt)
    return float(response.strip())

This ensures resilient data extraction, unaffected by UI redesigns.

Fiscal Intelligence & Multipliers

To calculate realistic ROI margins, OBrain applies strict fiscal multipliers based on Brazilian taxation and logistics:

[!NOTE] The Gap of Anticipation represents the financial margin captured by acting on the 1688/B2B layer before the B2C market becomes saturated.
