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 token contract on the Sonic blockchain, including the token name, symbol, number of decimals, and potentially other contract-level details such as total supply or owner address.
Example use cases
DeFi dashboard token display
“Pull the token name and symbol for contract 0x29219dd400f2Bf60E5a23d13Be72B486D4038894 on Sonic so I can label it correctly in my portfolio tracker.”
Token decimal lookup for swap math
“I need the decimal precision for the token at Sonic contract 0xA04BC7140c26fc9BB1F36B1A604C7A5a88fb0E70 so my DEX integration can calculate amounts correctly.”
Unknown contract token identification
“Can you tell me what token is deployed at Sonic contract address 0x6047828dc181963ba44974801FF68e538dA5eaF9 — I found it in a transaction and want to know what it is?”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/sonic/token/metadata?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve token metadata specifically on the Sonic blockchain network by contract address. Prefer this over generic multi-chain explorers when you know the contract is on Sonic and need fast, pay-per-call programmatic access without API key management.
Side effects
- Invalid or malformed contract address returns a 400 or error response
- Contract address not found on Sonic network returns null or empty metadata
- Non-token contract address (e.g. a proxy or NFT contract) may return incomplete or unexpected metadata
- Network timeouts or RPC issues on Sonic chain may cause 500 errors
- Payment failure via x402 protocol prevents the request from being processed
