CoinMarketCap DEX API

This skill covers CoinMarketCap's DEX (Decentralized Exchange) APIs for on-chain token data. Unlike CEX endpoints, these APIs fetch data directly from blockchain DEXs like Uniswap, PancakeSwap, and Raydium.

Authentication

All requests require an API key in the header:

curl -X GET "https://pro-api.coinmarketcap.com/v1/dex/platform/list" \
  -H "X-CMC_PRO_API_KEY: your-api-key"

Get your API key at: https://pro.coinmarketcap.com/login

Base URL

https://pro-api.coinmarketcap.com

POST vs GET Endpoints

Many DEX endpoints use POST for complex queries with body parameters. Always check the method:

1. GET endpoints pass parameters as query strings
2. POST endpoints pass parameters in JSON body with Content-Type: application/json

Common Use Cases

See use-cases.md for goal-based guidance on which endpoint to use:

1. Get DEX token price by contract address
2. Find a token's contract address by name
3. Get prices for multiple tokens at once
4. Check token security before trading
5. Find liquidity pools for a token
6. Find trending DEX tokens
7. Find today's biggest DEX gainers
8. Find newly launched tokens
9. Detect potential rug pulls (liquidity removal)
10. Get recent trades for a token
11. Get supported networks and DEXs
12. Get meme coins

API Overview

Common Workflows

Get DEX Token Information

1. Search for token: /v1/dex/search?keyword=PEPE
2. Get token details: /v1/dex/token?network_slug=ethereum&contract_address=0x...
3. Check security risks: /v1/dex/security/detail?network_slug=ethereum&contract_address=0x...

Analyze Token Liquidity

1. Get token pools: /v1/dex/token/pools?network_slug=ethereum&contract_address=0x...
2. Get liquidity history: /v1/dex/token-liquidity/query?network_slug=ethereum&contract_address=0x...

Find Trending Tokens

1. Get trending tokens: POST /v1/dex/tokens/trending/list with filters
2. Get gainers/losers: POST /v1/dex/gainer-loser/list
3. Find new tokens: POST /v1/dex/new/list

Monitor DEX Activity

1. Get recent transactions: /v1/dex/tokens/transactions?network_slug=ethereum&contract_address=0x...
2. Get pair quotes: /v4/dex/pairs/quotes/latest?network_slug=ethereum&contract_address=0x...

Key Parameters

Most DEX endpoints require:

1. network_slug or platform_crypto_id: Identifies the blockchain (ethereum, solana, bsc)
2. contract_address: The token's on-chain contract address

Use /v1/dex/platform/list to get valid network slugs and platform IDs.

Error Handling

Example error response:

{
  "status": {
    "error_code": 400,
    "error_message": "Invalid value for 'contract_address'"
  }
}

Rate Limits

Rate limits depend on your API plan. Check response headers:

1. X-CMC_PRO_API_KEY_CREDITS_REMAINING: Credits left
2. X-CMC_PRO_API_KEY_CREDITS_RESET: Reset timestamp

Response Format

All responses follow this structure:

{
  "status": {
    "timestamp": "2024-01-15T12:00:00.000Z",
    "error_code": 0,
    "error_message": null
  },
  "data": { ... }
}
