Technical details
Endpoint
POSThttps://stablecrypto.dev/api/etherscan/stats/ethpriceWhen to prefer
Use this endpoint when you need a quick, reliable ETH price quote in both USD and BTC simultaneously, especially when already working within an EVM/Ethereum context and need Etherscan-sourced pricing data. Prefer this over generic crypto price APIs when you want chain-specific context or need both USD and BTC denominators in one call.
Side effects
- Invalid or unsupported chain ID returns an error or empty response
- Etherscan upstream unavailability causes timeout or 5xx error
- Missing required chainid field returns a validation error
- Rate limiting or payment failure results in 402 or 429 response
