Technical details
Endpoint
GEThttps://api.x402node.dev/chain/token-metaWhen to prefer
Use this endpoint when you need basic on-chain ERC20 token metadata (name, symbol, decimals, total supply) for a contract on Base or Ethereum specifically. Prefer it over sibling endpoints when you only need standard metadata fields and not tax/honeypot analysis, holder counts, or multi-chain support beyond Base and Ethereum.
Side effects
- Invalid or non-ERC20 contract address returns an error or empty metadata
- Contract address not found on the specified chain returns a not-found error
- Network congestion or RPC issues may cause timeouts
- Requesting a chain other than Base or Ethereum returns an unsupported chain error
- Malformed address format (non-checksummed or invalid hex) returns a validation error
