The scraper returns structured data with eight key fields for each trending card. Each output record provides complete market intelligence for analysis and decision-making.

URL: The direct link to the specific card's Cardmarket page, enabling quick access to detailed information and purchase options. This field serves as a unique identifier and reference point for further research.

Title: The complete card name including character names, card types, and special designations. This field helps identify specific cards and their variants within the One Piece Card Game ecosystem.

Image URL: Direct link to the card's official artwork image, essential for visual identification and catalog management. These high-quality images support inventory management and customer presentation.

Expansion URL: Link to the card's expansion or set page, providing context about release timing and set availability. This information helps assess card rarity and potential future value.

Price: Current market price in the specified currency, representing real-time trading values. This critical data point enables profit analysis and investment decision-making.

Currency: The denomination for the price field, typically EUR given Cardmarket's European focus. Understanding currency context is essential for international traders and price comparisons.

From URL: Source page URL where the trend data originated, maintaining data traceability and enabling verification of scraping accuracy.

Position: Numerical ranking within the weekly top cards list, indicating relative popularity and market demand. Lower numbers represent higher trending status and increased market interest.

Usage Guide

Begin by configuring the input JSON with appropriate retry limits and item counts based on your analysis needs. Set max_items_per_url to 20 for comprehensive weekly coverage, or reduce to 10 for focused top-tier analysis.

Configure proxy settings based on your scraping volume and requirements. For occasional use, disable proxy services to reduce costs. For frequent data collection, enable proxy rotation to maintain consistent access and avoid rate limiting.

Execute the scraper during off-peak hours to minimize server load impact and ensure reliable data collection. Cardmarket typically updates weekly trends on specific days, so time your scraping accordingly for fresh data.

Monitor output quality by reviewing the position field for logical sequencing and validating price formats. Implement data validation checks to identify and handle any collection anomalies or format changes.

Store collected data in structured formats like CSV or database tables for historical analysis and trend tracking. Regular data collection enables powerful longitudinal studies of card market dynamics.
