Aibijia Price Comparison

Aibijia Price Comparison Platform

Skill by ara.so — Daily 2026 Skills collection.

Aibijia is a multi-platform price scraping and comparison website for AI tokens (ChatGPT Plus CDKs, API keys, etc.). It aggregates prices from various resellers/agents across platforms, helping users find the cheapest reliable source and avoid scams.

What This Project Does

• Scrapes token/CDK prices from multiple card-selling platforms (卡网)
• Compares prices across vendors for the same type of AI account (e.g., ChatGPT Plus, GPT Pro)
• Aggregates vendor reliability info via community submissions
• Exposes price differences between resellers sourcing from the same upstream

Project Structure

Since the repo is primarily a community/data project with a web frontend, the core components are:

AIbijia/
├── assets/           # Static assets (banner, images)
├── data/             # Price data / scraped results (JSON/CSV)
├── scrapers/         # Platform price scrapers
├── frontend/         # Website UI (aibijia.org)
└── SKILL.md

Vendor Submission API

The site exposes a submission endpoint for community-sourced vendors:

def submit_vendor(vendor_info: dict) -> dict:
    """

      - token_type: str    e.g. "ChatGPT Plus CDK"

Data Storage Pattern

import json

from datetime import datetime

DATA_DIR = Path("./data")

def save_price_snapshot(listings: list[dict], token_type: str):

    date_str = datetime.utcnow().strftime("%Y-%m-%d")

    snapshot = {
        "token_type": token_type,
        "captured_at": datetime.utcnow().isoformat(),
        "count": len(listings),
        "listings": listings,
    }
    
    with open(filename, "w", encoding="utf-8") as f:
        json.dump(snapshot, f, ensure_ascii=False, indent=2)
    
    print(f"Saved {len(listings)} listings to {filename}")


def load_latest_snapshot(token_type: str) -> dict | None:
    """Load the most recent snapshot for a token type."""
    pattern = f"{token_type.replace(' ', '_')}_*.json"
    files = sorted(DATA_DIR.glob(pattern), reverse=True)
    
    if not files:
        return None
    
    with open(files[0], encoding="utf-8") as f:
        return json.load(f)
