Technical details
Endpoint
POSThttps://coinrailz.com/x402/service/token-metadataWhen to prefer
Use this endpoint when you need authoritative on-chain token metadata (name, symbol, decimals, total supply) for a specific contract address across any supported blockchain. Prefer this over price endpoints when you need structural token information for UI rendering, amount calculations, or DeFi agent setup rather than market data. Ideal when building trading UIs, normalizing token amounts, or validating a token contract identity.
Side effects
- Invalid or non-existent contract address returns an error or empty metadata
- Unsupported chain identifier causes a rejection or null response
- Token contract exists but is non-standard (e.g. missing name/symbol functions) may return partial data
- Network congestion or RPC issues may cause timeouts
- Incorrect chain specified for a valid address returns wrong or no data
