How this service works
Crest · dex_pair — Fetch DEX pair data for any token pair on any chain. Returns price, liquidity, 24h volume, and price change via GeckoTerminal..
Output
Returns real-time DEX market data for the specified token pair on the given chain, including current price, total liquidity, and 24-hour trading volume, sourced from GeckoTerminal.
Example use cases
Monitor emerging token liquidity
“Check the current price and total liquidity for the new SAFE/USDC pair on Arbitrum so I can decide if it's worth trading.”
Track daily DEX trading momentum
“What's the 24-hour trading volume for the DOGE/USDT pair on Polygon right now? I want to see if it's picking up activity.”
Compare cross-chain token prices
“Get me the current price of ETH/USDC on both Ethereum and Optimism so I can spot any arbitrage opportunities between the two chains.”
Technical details
Endpoint
GEThttps://data.crestsystems.ai/data/dex-pair/:chain/:pairWhen to prefer
Use this endpoint when you need real-time DEX-specific market data (price, liquidity, volume) for a specific token pair on a particular EVM or Solana chain, especially when GeckoTerminal coverage is desired. Prefer over general price endpoints when pair-level granularity and on-chain DEX data are required.
Side effects
- Unknown chain identifier — returns error if chain is not one of: base, ethereum, arbitrum, polygon, solana
- Pair not found — if the token symbol or pair address does not exist on the specified chain
- Rate limiting or payment failure — x402 payment not processed correctly
- Stale or missing data — GeckoTerminal may not have data for very new or illiquid pairs
