How this service works
Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.
Output
Returns a JSON object with the timestamp of the price (as_of), chain identifier (eth), ETH price in USD (eth_usd), and ETH price in BTC (eth_btc). Example: {as_of: '2026-07-31T03:42:30+00:00', chain: 'eth', eth_btc: 0.02970669, eth_usd: 1867.87}
Example use cases
Real-time ETH portfolio valuation
“What is the current price of Ethereum in USD? I want to calculate the current value of my 3.5 ETH holdings.”
ETH/BTC ratio monitoring
“Check the current ETH to BTC ratio for me — I'm watching whether ETH is strengthening or weakening against Bitcoin today.”
Crypto price alert trigger
“Fetch the live ETH price right now so I can check if it has crossed my $2,000 alert threshold.”
Technical details
Endpoint
GEThttps://x402financialdata.com/eth-priceWhen to prefer
Prefer this endpoint when you need a no-subscription, pay-per-call ETH price feed and are already operating in the x402 micropayment ecosystem with USDC on Base or Solana. Ideal for agents that call infrequently and want to avoid monthly API key commitments. Not ideal if you need high-frequency polling where per-call fees accumulate.
Side effects
- Payment rejected or insufficient USDC balance — HTTP 402 returned with payment requirements
- Network timeout if the x402 payment channel is congested
- Stale or delayed price data if the upstream price feed is lagging
- Unsupported payment network if USDC is not on Base or Solana
