CardHunt

No description of NumPy yet.

CardHunt scans eBay for Pokémon cards with a lot of PSA 10 upside, checks that each listing is still for sale and estimates the centering from the photos before you click. Behind it is the PSA population report plus recent sales prices, so every find shows the chance of a PSA 10, 9 or 8 and the...

Features and specs

What each product offers, as listed by its team.

NumPy 5 features
CardHunt 5 features
  • Performance
    NumPy operations are executed with highly optimized C and Fortran libraries, making them significantly faster than standard Python arithmetic operations, especially for large datasets.
  • Versatility
    NumPy supports a vast range of mathematical, logical, shape manipulation, sorting, selecting, I/O, and basic linear algebra operations, making it a versatile tool for scientific and numeric computing.
  • Ease of Use
    NumPy provides an intuitive, easy-to-understand syntax that extends Python's ability to handle arrays and matrices, lowering the barrier to performing complex scientific computations.
  • Community Support
    With a large and active community, NumPy offers extensive documentation, tutorials, and support for troubleshooting issues, as well as continuous updates and enhancements.
  • Integrations
    NumPy integrates seamlessly with other libraries in Python's scientific stack like SciPy, Matplotlib, and Pandas, facilitating a streamlined workflow for data science and analysis tasks.

Possible disadvantages

  • Memory Consumption
    NumPy arrays can consume large amounts of memory, especially when working with very large datasets, which can become a limitation on systems with limited memory capacity.
  • Learning Curve
    For users new to scientific computing or coming from different programming backgrounds, understanding the intricacies of NumPy's operations and efficient usage can take time and effort.
  • Limited GPU Support
    NumPy primarily runs on the CPU and doesn't natively support GPU acceleration, which can be a disadvantage for extremely compute-intensive tasks that could benefit from parallel processing.
  • Dependency on Python
    Since NumPy is a Python library, it depends on the Python runtime environment. This can be a limitation in environments where Python is not the primary language or isn't supported.
  • Indexing Complexity
    Although NumPy's slicing and indexing capabilities are powerful, they can sometimes be complex or unintuitive, especially for multi-dimensional arrays, leading to potential errors and confusion.
  • Live eBay finds
    Pokémon cards listed on eBay with the most PSA 10 upside, re-checked so you only see listings that are still for sale
  • Centering check
    Front and back centering estimated from the listing photos before you click
  • PSA 10 odds and profit
    Chance of a PSA 10 from the PSA population report and the expected profit after grading, shipping and selling fees
  • Total cost to your door
    Prices include shipping and import costs to your country, not just the listing price
  • Price insights
    Shows which cards trade near their own 6-month low

Questions & Answers

As answered by people managing NumPy and CardHunt.

What makes your product unique?

CardHunt's answer:

CardHunt scans eBay for Pokémon cards with PSA 10 upside, checks that each listing is still for sale, and estimates the centering from the listing photos before you click. Every find shows the chance of a PSA 10 (from the PSA population report) and the expected profit after grading, shipping and selling fees, and it flags the traps: cards that look like a big win on paper but lose money on average.

Why should a person choose your product over its competitors?

CardHunt's answer:

Most tools show either a price or a PSA population count. CardHunt combines both with live eBay listings: the chance of a PSA 10, the expected profit after grading, shipping and selling fees, a centering estimate from the photos, and the total cost including shipping and import to your country, so you can decide before you buy. These are estimates, not guarantees: the PSA population report only counts cards people chose to submit, and centering is an estimate from photos, not a grade.

How would you describe the primary audience of your product?

CardHunt's answer:

Pokémon card collectors and flippers who buy raw cards on eBay to send to PSA, and want to know which listings are actually worth grading before they spend money on the card and the grading fee.

What's the story behind your product?

CardHunt's answer:

CardHunt is built solo by Stefan in the Netherlands. Judging a raw Pokémon card for grading is hard because you need the price, the PSA population data and the card's condition at the same time, and the good listings sell fast. CardHunt does that math for every eBay listing, checks that it is still for sale and estimates the centering from the photos, so you only spend your time on cards that can actually pay off.

Which are the primary technologies used for building your product?

CardHunt's answer:

Next.js and React with TypeScript on the frontend (hosted on Vercel), a Python FastAPI backend (hosted on Railway), PostgreSQL on Supabase, Clerk for sign-in, the eBay APIs for live listings, and computer vision to estimate centering from listing photos. Prices and PSA population data come from third-party data providers.
