Use Pokemon Price Tracker API with AI Coding Tools

The Rise of Vibe Coding

"Vibe coding" - using AI assistants to write code through natural language - is transforming how developers build applications. Tools like Claude Code, Cursor, and Cline let you describe what you want and watch the code materialize.

But there's a catch: AI tools need to understand your API to use it effectively.

That's why we've made the Pokemon Price Tracker API fully AI-readable. Just point your AI assistant to our documentation URLs, and it can write integration code automatically.

AI-Friendly Documentation URLs

We provide two formats optimized for AI consumption:

OpenAPI Specification (Complete)

https://www.pokemonpricetracker.com/api/openapi

Full machine-readable API spec with all endpoints, parameters, response schemas, and examples.

llms.txt (Quick Reference)

https://www.pokemonpricetracker.com/llms.txt

Concise markdown summary designed for LLM context windows. Perfect for quick tasks.

How to Use with Popular AI Tools

Claude Code / Claude CLI

Add these URLs to your project context or paste them directly in your prompt:

Read the API docs at https://www.pokemonpricetracker.com/llms.txt and help me build a Pokemon card price checker in TypeScript.

Or include in your project's CLAUDE.md file:

## External APIs

Pokemon Price Tracker API:
- Docs: https://www.pokemonpricetracker.com/api/openapi
- Quick ref: https://www.pokemonpricetracker.com/llms.txt
- Auth: Bearer token in Authorization header

Cursor

In Cursor, use the @web command to fetch the API docs:

@web https://www.pokemonpricetracker.com/llms.txt

Create a React component that searches for Pokemon cards and displays prices

Or add to your project's .cursorrules file:

When working with Pokemon card prices, reference the API at:
https://www.pokemonpricetracker.com/api/openapi

Cline / Continue

Add the API documentation to your context:

Fetch https://www.pokemonpricetracker.com/llms.txt and use it to build a price lookup feature for my Discord bot.

GitHub Copilot

While Copilot doesn't fetch URLs directly, you can paste the llms.txt content into a comment block:

/**
 * Pokemon Price Tracker API Reference:
 * Base URL: https://www.pokemonpricetracker.com/api/v2
 * Auth: Bearer token
 *
 * GET /cards - Search cards (params: search, setId, limit)
 * GET /sets - List sets
 * GET /sealed-products - Sealed product prices
 */

// Now Copilot understands the API
async function searchCards(query: string) {
  // Copilot will autocomplete with correct API calls
}

Real-World Examples

Example 1: Quick Price Lookup (TypeScript)

Prompt to Claude Code:

Using the Pokemon Price Tracker API at https://www.pokemonpricetracker.com/llms.txt, create a function that searches for a card by name and returns its price.

Claude generates:

const API_KEY = process.env.POKEMON_API_KEY;
const BASE_URL = 'https://www.pokemonpricetracker.com/api/v2';

async function getCardPrice(cardName: string): Promise {
  const response = await fetch(
    `${BASE_URL}/cards?search=${encodeURIComponent(cardName)}&limit=1`,
    {
      headers: {
        'Authorization': `Bearer ${API_KEY}`,
      },
    }
  );

  const data = await response.json();

  if (data.data && data.data.length > 0) {
    const card = data.data[0];
    return {
      name: card.name,
      setName: card.setName,
      price: card.prices.market,
    };
  }

  return null;
}

// Usage
const card = await getCardPrice('Charizard VMAX');
console.log(`${card.name} from ${card.setName}: $${card.price}`);

Example 2: Discord Bot Command (Node.js)

Prompt to Cursor:

@web https://www.pokemonpricetracker.com/llms.txt

Create a Discord slash command that lets users look up Pokemon card prices. Include price, set name, and an image.

Cursor generates:

import { SlashCommandBuilder, EmbedBuilder } from 'discord.js';

export const data = new SlashCommandBuilder()
  .setName('cardprice')
  .setDescription('Look up a Pokemon card price')
  .addStringOption(option =>
    option.setName('card')
      .setDescription('Card name to search')
      .setRequired(true));

export async function execute(interaction) {
  await interaction.deferReply();

  const cardName = interaction.options.getString('card');

  const response = await fetch(
    `https://www.pokemonpricetracker.com/api/v2/cards?search=${encodeURIComponent(cardName)}&limit=1`,
    {
      headers: { 'Authorization': `Bearer ${process.env.POKEMON_API_KEY}` }
    }
  );

  const { data } = await response.json();

  if (!data || data.length === 0) {
    return interaction.editReply('Card not found!');
  }

  const card = data[0];

  const embed = new EmbedBuilder()
    .setTitle(card.name)
    .setDescription(`**Set:** ${card.setName}\n**Rarity:** ${card.rarity}`)
    .addFields(
      { name: 'Market Price', value: `$${card.prices.market?.toFixed(2) || 'N/A'}`, inline: true },
      { name: 'Low Price', value: `$${card.prices.low?.toFixed(2) || 'N/A'}`, inline: true },
    )
    .setImage(card.imageCdnUrl400)
    .setColor(0xFFCC00);

  await interaction.editReply({ embeds: [embed] });
}

Example 3: React Price Checker Component

Prompt to Cline:

Using https://www.pokemonpricetracker.com/llms.txt, build a React component with a search input that displays Pokemon card prices with images. Use Tailwind for styling.

Cline generates:

import { useState } from 'react';

interface Card {
  tcgPlayerId: string;
  name: string;
  setName: string;
  rarity: string;
  prices: { market: number; low: number };
  imageCdnUrl400: string;
}

export function CardPriceSearch() {
  const [query, setQuery] = useState('');
  const [cards, setCards] = useState([]);
  const [loading, setLoading] = useState(false);

  const searchCards = async () => {
    if (!query.trim()) return;

    setLoading(true);
    try {
      const res = await fetch(
        `/api/pokemon-proxy?search=${encodeURIComponent(query)}&limit=12`
      );
      const data = await res.json();
      setCards(data.data || []);
    } finally {
      setLoading(false);
    }
  };

  return (
    
      
         setQuery(e.target.value)}
          onKeyDown={(e) => e.key === 'Enter' && searchCards()}
          placeholder="Search for a Pokemon card..."
          className="flex-1 px-4 py-2 border rounded-lg focus:ring-2 focus:ring-blue-500"
        />
        
          {loading ? 'Searching...' : 'Search'}
        
      

      
        {cards.map((card) => (
          
            
            {card.name}
            {card.setName}
            
              ${card.prices.market?.toFixed(2) || 'N/A'}
            
          
        ))}
      
    
  );
}

Tips for Better AI Integration

1. Be Specific About What You Need

Less effective:

Make a Pokemon price app

More effective:

Using https://www.pokemonpricetracker.com/llms.txt, create a Next.js API route that:
1. Accepts a card name as query parameter
2. Fetches price data from Pokemon Price Tracker API
3. Returns formatted response with name, set, price, and image URL
4. Handles errors gracefully

2. Include Authentication Context

The Pokemon API requires Bearer token authentication.
Store the API key in POKEMON_API_KEY environment variable.
Never expose the key in client-side code.

3. Specify Response Handling

The API returns data in this format:
{
  "data": [...cards],
  "metadata": { total, count, hasMore }
}

Always check if data exists before accessing array items.

4. Request Rate Limit Awareness

The API has rate limits (60 calls/minute on free tier).
Add appropriate error handling for 429 responses.
Consider caching results for repeated queries.

Advanced: MCP Server Integration

For the ultimate Claude Code experience, we're exploring an MCP (Model Context Protocol) server that would give Claude direct tool access to query Pokemon card prices.

Coming soon:

{
  "mcpServers": {
    "pokemon-prices": {
      "command": "npx",
      "args": ["@pokemonpricetracker/mcp-server"]
    }
  }
}

This would enable prompts like:

Use the pokemon-prices tool to find the top 5 most expensive Charizard cards
