How this service works
High-speed API suite for AI processing, web scraping, and smart data utilities across 57+ blockchain networks. Pay-per-call via x402.
Output
Returns on-chain metadata for the specified Kaia token contract, typically including token name, symbol, decimal precision, and potentially total supply or other ERC-20/KIP-7 standard fields as stored on-chain.
Example use cases
DeFi dashboard token enrichment
“I'm building a Kaia DeFi dashboard and need to display the token name, symbol, and decimals for the contract at 0x5a3D0a33E9e09e0c23a5E7b9d4f65B6E1A2b3C4D — can you fetch that metadata?”
Wallet token display resolution
“My wallet just received tokens from contract address 0x9fBa0Cd8E7F3a2B1D4E5C6A7b8D9E0F1A2B3C4D on the Kaia network — what's the token name and symbol so I can label it properly?”
Smart contract token audit
“Can you pull the on-chain metadata for the Kaia token contract 0x1A2B3C4D5E6F7A8B9C0D1E2F3A4B5C6D7E8F9A0B so I can verify its name and decimal configuration?”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/kaia/token/metadataWhen to prefer
Choose this endpoint when you specifically need token metadata from the Kaia (formerly Klaytn) blockchain network. It is ideal for DeFi apps, wallets, and analytics tools that need to enrich contract addresses with human-readable token information on Kaia, without running your own Kaia node or indexer.
Side effects
- Invalid or malformed contract address returns an error
- Contract address does not correspond to a token contract (e.g. EOA or non-token contract) may return empty or error
- Kaia RPC node unavailability causes timeout or 503
- Non-existent contract address on Kaia network returns not-found error
- Payment failure (x402) results in 402 response before query is executed
