Example use cases
Example prompt

Technical details
Endpoint
GEThttps://pro-api.coinmarketcap.com/x402/v4/dex/pairs/quotes/latestWhen to prefer
Use this endpoint when you need real-time quote data for a specific DEX trading pair and you already have the contract address. Ideal for DeFi applications, trading bots, portfolio trackers, or price alert systems that need precise on-chain pair pricing. Prefer this over general crypto quote endpoints when the asset is a DEX-listed token pair rather than a top-level CMC-listed coin.
Side effects
- Invalid or non-existent pair_address returns an error or empty result
- Unsupported network_id may return no data
- Malformed comma-separated pair_address list causes validation error
- Requesting a pair on a network where CoinMarketCap has no data returns empty
- Payment failure via x402 protocol blocks the request
- Rate limiting if too many requests are made in quick succession
