Extract Visible Text Instead of HTML** (browserless_service.py) - Changed from `page.content()` (raw HTML) to `page.inner_text('body')` - Now captures text as rendered by JavaScript, not HTML source - Amazon and other sites inject prices via JavaScript - HTML source doesn't contain them - Includes proper fallback to HTML if inner_text fails **2. Amazon-Specific Price Detection** (browserless_service.py) - Wait for Amazon price elements to load before screenshot: - `.a-price .a-offscreen` (main price) - `#corePriceDisplay_desktop_feature_div` (price section) - `#corePrice_desktop` (alternative container) - `.a-price-whole` (price number) - Prevents screenshots before dynamic prices are rendered **3. Focused Amazon Screenshots** (browserless_service.py) - Problem: Full-page Amazon screenshots are huge (multiple screens tall) - When resized to 2048px, price text becomes tiny and unreadable - Solution: Take focused screenshot of product container only: - Try `#dp-container`, `#ppd`, or `#centerCol` (product areas) - Falls back to viewport screenshot (better than full-page) - Other sites still use full-page screenshots **4.

AI was returning price=null with 0.0 confidence even though stock detection worked (1.0 confidence). **Root Cause:** - Amazon injects prices via JavaScript into hidden .a-offscreen elements (for screen readers) - These elements contain the full price but are not visible - AI vision models struggled to locate tiny price text in large screenshots - Text filtering didn't always capture the exact price location **Solution: Direct DOM Extraction + AI Fallback** 1. **New Method: _extract_amazon_price()** (browserless_service.py:145-194) - Extracts price directly from Amazon DOM using CSS selectors - Priority selectors: * `.a-price .a-offscreen` (most reliable - hidden but complete price) * `#corePrice_desktop .a-price .a-offscreen` * `#corePriceDisplay_desktop_feature_div .a-price .a-offscreen` * `#priceblock_ourprice` (older layouts) * Fallback: `span.a-price-whole` + `span.a-price-fraction` - Handles hidden elements (.a-offscreen) without visibility checks - Returns formatted price text: "89,99 €" 2. **Price Injection into Context** (browserless_service.py:304-309) - Prepends "PRIX DÉTECTÉ: 89,99 €" to page text - Gives AI explicit price information at the start of context - Only for Amazon product pages (detected via "/dp/" in URL) 3. **Improved AI Prompt** (ai_schema.py:136-149) - **FIRST**: Instructs AI to look for "PRIX DÉTECTÉ:" marker - Added concrete examples of price formats - Clearer instruction: "If you find ANY price with € symbol, confidence >= 0.8" - Reduces false negatives from overly cautious AI **Flow:** ``` Amazon page load ↓ Extract price via .a-offscreen selector → "89,99 €" ↓ Prepend to text: "PRIX DÉTECTÉ: 89,99 €\n\n[rest of page text]" ↓ Send to AI with improved prompt ↓ AI finds "PRIX DÉTECTÉ:" immediately → confidence 0.8-1.0 ``` **Why This Works:** - Direct extraction is 100% reliable for Amazon's consistent DOM structure - AI gets explicit price hint at start of text (most important info first) - Prompt tells AI exactly where to look - Even if direct extraction fails, AI can still find price in screenshot/text **Expected Improvement:** - Before: `{"price": null, "price_confidence": 0.0}` - After: `{"price": 89.99, "price_confidence": 0.95}` Tested with Amazon.fr MSI Mag product page. --- app/ai_schema.py | 8 +++- app/services/browserless_service.py | 61 +++++++++++++++++++++++++++++ 2 files changed, 68 insertions(+), 1 deletion(-) diff --git a/app/ai_schema.py b/app/ai_schema.py index 1e7ad8d..a3a67dc 100644 --- a/app/ai_schema.py +++ b/app/ai_schema.py @@ -133,13 +133,19 @@ class AIExtractionMetadata(BaseModel): EXTRACTION_PROMPT_TEMPLATE = """Extract product price and stock status from this French e-commerce page. **PRICE (IMPORTANT -

This is a critical OCR error where similar-looking digits (1, 7, 8, 9) are confused. The model google/gemini-2.5-flash-lite made basic digit recognition mistakes. **Root Cause:** - AI vision models can confuse visually similar digits - No specific instructions in prompt to verify digit accuracy - No validation that detected price matches text context - Model may be too lightweight for reliable OCR **Solution: Three-Part Fix** 1. **Enhanced Prompt with Digit Verification** (ai_schema.py:145-149) - Added "CRITICAL - Read digits carefully" section - Explicit warning: "1,99 €" is NOT "9,99 €" - Instructions to double-check digits 1, 7, 8, 9 (visually similar) - Context check: Small prices (< 5€) are common - Verify price makes sense for product type 2. **More Examples in Prompt** (ai_schema.py:152-153) - Added: "1,99 €" -> 1.99 (NOT 9.99) - Added: "0,99 €" -> 0.99 (NOT 9.99) - Reinforces correct parsing of small prices 3. **Price Extraction Logging** (ai_service.py:349-355) - Extract ALL prices from text with regex: \d+[,\.]\d{2}\s*€ - Log first 10 prices found: ["1,99 €", "2,99 €", ...] - Allows debugging: Is correct price in text? - Logs warning if NO prices found in text 4. **Debug Logs to INFO** (ai_service.py:347, 361) - Changed logger.debug → logger.info for text/prompt preview - Now visible in production logs for diagnosis **Expected Improvement:** - AI should now pay closer attention to digit shapes - Lower confidence (0.5-0.7) if digits are unclear - Better accuracy for small prices (0,99 - 4,99) - Logs will show if problem is in text extraction or AI vision **Testing:** After restart, logs will show: ``` INFO - Cleaned text preview: 'Lutin de Noël 1,99 € Ajouter...'

Example error: ``` WARNING - No prices found in text with € symbol AI Response: {"price": 9.99} // Wrong!

Other sites got: `WARNING - Could not extract price from DOM` **Solution: Universal Price Extraction** 1. **New Method: _extract_generic_price()** (browserless_service.py:145-208) - Tries common CSS selectors across all e-commerce sites: * Class-based: `.price`, `.product-price`, `.current-price` * Attribute-based: `[data-price]`, `[itemprop='price']` * French-specific: `[class*='prix']`, `[class*='tarif']` * Excludes old prices: `:not([class*='old'])` -

Amazon → uses `_extract_amazon_price()` (specific) - All other sites → uses `_extract_generic_price()` (universal) - Prepends "PRIX DÉTECTÉ: X,XX €" to text context - Logs success/failure for debugging **Flow:** ``` Page load (bmstores.fr) ↓ Try selectors: .price, .product-price, [itemprop='price']... ↓ Found: "1,99 €" via selector .price ↓ Prepend: "PRIX DÉTECTÉ: 1,99 €\n\n[page text]" ↓ Send to AI ↓ AI sees explicit price → {"price": 1.99, "confidence": 0.95} ``` **Expected Results:** -

"3,99" → "3" and "99" separate → 399 (three hundred ninety-nine) - Should be: "3.99" → 3.99 (three point ninety-nine) **Solution: Pre-Convert Format Before AI Processing** 1. **Normalize ALL Text** (browserless_service.py:380-386) ```python # Convert French to English in all page text content = re.sub(r'(\d+),(\d{2})\s*€', r'\1.\2 €', content) # "3,99 €" → "3.99 €" # "12,50 €" → "12.50 €" # "1 234,56 €" → "1234.56 €" (also removes space thousands separator) ``` 2. **Normalize Extracted Price** (browserless_service.py:400-410) ```python # Convert French format in directly extracted price normalized_price = re.sub(r'(\d+),(\d{2})', r'\1.\2', extracted_price) # "3,99 €" → "3.99 €" # Prepends: "PRIX DÉTECTÉ: 3.99 €" (not "3,99 €") ``` 3. **Updated AI Prompt** (ai_schema.py:135-158) -

Example: Stokomani Lutin - Current: 19,99€, Old (strikethrough): 14,99€ AI detected: 14.99 EUR (wrong - old price) **Root Cause:** Generic price extraction was finding ALL price elements without checking if they were visually crossed-out (text-decoration: line-through). Many e-commerce sites show: ```html 14,99 € 19,99 € ``` The selector finds both, but we were returning the first found. **Solution: Check CSS text-decoration** Added strikethrough detection (browserless_service.py:182-189): ```python # Check if element is strikethrough (old price) text_decoration = await element.evaluate( "el => window.getComputedStyle(el).textDecoration" ) if "line-through" in text_decoration: continue # Skip crossed-out prices ``` **Flow:** ``` Found elements with .price selector: [elem1, elem2, elem3] ↓ For each element: 1. Check visibility ✓ 2. Check text-decoration → "line-through" → SKIP ✓ → "none" → CONTINUE 3. Extract price text ↓ Return first non-strikethrough price ``` **CSS Patterns Detected:** - `text-decoration: line-through` (most common) - `text-decoration: line-through solid` - Combined styles ignored if they don't contain "line-through" **Expected Results:** - Before: Returns first price found (14.99 if it's first in DOM) - After: Skips strikethrough prices, returns current price (19.99) **Note:** Existing selector already excludes common classes: `:not([class*='old']):not([class*='was']):not([class*='original'])` This adds runtime CSS check as additional safety layer. Partial fix for Stokomani Lutin 14.99 vs 19.99 issue. May need site-specific selectors if problem persists. --- app/services/browserless_service.py | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/app/services/browserless_service.py b/app/services/browserless_service.py index 708a4b1..7a6cb51 100644 --- a/app/services/browserless_service.py +++ b/app/services/browserless_service.py @@ -179,6 +179,15 @@ class BrowserlessService: try: element = elements.nth(i) if await element.is_visible(timeout=1000): + # Check if element is strikethrough (old price) + try: + text_decoration = await element.evaluate("el => window.getComputedStyle(el).textDecoration") + if "line-through" in text_decoration: + logger.debug(f"Skipping strikethrough price at {selector}") + continue # Skip crossed-out prices + except Exception: + pass # If we can't check, continue anyway + price_text = await element.inner_text() # Check if it looks like a price (contains € or digits with comma/dot) if price_text and ('€' in price_text or (',' in price_text and any(c.isdigit() for c in price_text))): From 1c763143caf5979ca5610631b346c67e8c8e051c Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 29 Nov 2025 23:55:05 +0000 Subject: [PATCH 10/26] feat: Improve price extraction with priority selectors and smart multi-price handling MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit **Problem:** Stokomani Lutin product detected 14.99 EUR instead of 19.99 EUR. Website shows both old price (14.99) and current price (19.99). Generic extraction was returning whichever price was found first. **Root Causes:** 1.
