How this service works
Unified token info across all chains - essential building block for trading agent UIs (B2B2C infrastructure)
Output
A JSON object containing unified token metadata for the queried token across chains, including fields such as token name, symbol, decimal precision, contract address, chain ID, token standard (e.g. ERC-20), and a success status with timestamp.
Example use cases
Example prompt
“Can you pull the full token metadata for USDC on Base — I need the contract address, decimals, symbol, and token standard so I can build out the trading interface.”
Technical details
Endpoint
POSThttps://coinrailz.com/x402/token-metadataWhen to prefer
Use this endpoint when you need authoritative, cross-chain token metadata (name, symbol, decimals, contract details) as a foundational building block for trading UIs, transaction builders, or DeFi agents — especially when you need consistent data across multiple chains in a single call rather than querying individual chain RPC nodes.
Side effects
- Unknown or unsupported token contract address returns error or empty result
- Unsupported blockchain network returns failure response
- Malformed contract address input causes validation error
- Token not indexed yet on a newly deployed contract
- Rate limiting or payment failure (x402) if USDC payment not properly attached
