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 the token's ID, current USD price, all-time high USD price, human-readable name, and ticker symbol (e.g. {id: 'bitcoin', usd: 60000, name: 'Bitcoin', symbol: 'btc', ath_usd: 70000}). Payment of $0.002 USDC is deducted per successful call via x402 on Base mainnet.
Example use cases

Endpoint
GEThttps://x402-20260909-agent.projectk.org/tokensWhen to prefer
Prefer this endpoint when you need real-time token price data without API key registration, especially in autonomous agent workflows where wallet-based micropayments (x402/USDC on Base) are already supported. Ideal for one-off or low-frequency lookups where a subscription would be overkill, or when operating in a trustless, account-free environment.
Side effects
- Invalid or unrecognized token ID returns an error or empty result
- Insufficient USDC balance in wallet causes payment failure and no data returned
- Network or Base mainnet congestion may delay payment settlement
- Token ID must match the provider's canonical slug (e.g. 'bitcoin' not 'BTC')
- x402 facilitator downtime may block payment and data delivery
