How this service works
Current ETH price in USD and BTC, from Etherscan's V2 API. A quick single-value price check -- for market cap/volume/supply detail use /crypto-prices instead. Not address-specific. $0.005/call.
Output
Returns the current ETH price as a single snapshot: ETH/USD and ETH/BTC values sourced from Etherscan's V2 API. Does not include market cap, volume, or circulating supply — for those use the /crypto-prices endpoint instead.
Example use cases
Real-time ETH portfolio valuation
“What is ETH trading at right now in USD so I can calculate the current value of my 5 ETH holdings?”
ETH/BTC cross-rate check
“Can you pull the latest Ethereum price in BTC for me? I want to see how ETH is doing relative to Bitcoin today.”
Automated price alert trigger
“Fetch me the current ETH price in USD — I want to know if it's crossed $3,000 so I can decide whether to rebalance.”
Technical details
Endpoint
GEThttps://www.x402financialdata.com/eth-priceWhen to prefer
Choose this endpoint when you need a fast, lightweight ETH price snapshot in USD and BTC with minimal overhead. It is ideal for quick checks, triggering price alerts, or enriching transaction data with current ETH value. If you need market cap, volume, or supply data, use /crypto-prices instead. At $0.005/call, it is cost-effective for high-frequency price polling.
Side effects
- Unsupported chain parameter (only 'eth' is supported) returns an error
- Etherscan upstream API unavailability may cause request failure or stale data
- Payment failure (insufficient USDC balance or x402 protocol error) results in 402 response
- Network timeout if Etherscan V2 is slow to respond
