How this service works
Pay-per-call live data APIs settled in USDC on Base (Ethereum) mainnet via x402. No accounts, no API keys — just a wallet. Covers live crypto ticker prices, GitHub repo metrics, Base gas price, and token market data. Payment goes to the operator's Base address.
Output
A JSON object containing a Unix timestamp, a source field (coingecko), and a prices map with USD values for USDC, Solana, Bitcoin, and Ethereum. Example: {ts: 123456, prices: {bitcoin: {usd: 60000}, ethereum: {usd: 3000}, solana: {usd: 150}, usdc: {usd: 1}}, source: 'coingecko'}.
