Technical details
Endpoint
GEThttps://pro-api.coingecko.com/api/v3/x402/onchain/simple/networks/eth/token_price/0xdac17f958d2ee523a2206206994597c13d831ec7When to prefer
Use this endpoint when you specifically need the on-chain price of USDT (or the ERC-20 token at 0xdac17f958d2ee523a2206206994597c13d831ec7) on the Ethereum network, sourced directly from on-chain DEX data via CoinGecko Pro. Prefer this over CoinGecko's off-chain simple price endpoint when you need DEX-sourced pricing, or when you need on-chain market metrics like total reserve in USD. This is especially useful for DeFi applications, arbitrage monitoring, or any workflow requiring verifiable on-chain price feeds for Ethereum tokens.
