How this service works
Market and on-chain data, paid per call in USDC on Base through the x402 protocol. No accounts, no API keys. Sources are public data providers; the value added here is keyless access, edge caching, multi-source fallback and normalised responses.
Output
A normalized JSON object containing on-chain token metadata such as token name, symbol, decimals, contract address, and available market data fields sourced from public providers with edge caching and multi-source fallback.
Example use cases

“What token is the contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base? Give me its name, symbol, and decimals.”
Market data lookup for portfolio tracker
“Fetch the current market data and metadata for the USDC token on the Base network — I need the normalized info including symbol, decimals, and price if available.”
Token validation before a swap
