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 token metadata for the given contract address, including token name, symbol, number of decimals, total supply, and potentially other ERC20/token-standard fields stored on-chain.
Example use cases
Identify unknown token contract
“I found this contract address 0x6B175474E89094C44Da98b954EedeAC495271d0f in my wallet — can you look up what token it is, its symbol, and how many decimals it uses?”
DeFi dashboard token enrichment
“I'm building a DeFi dashboard and need to display the full metadata for the USDC token at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 — fetch the name, symbol, decimals, and total supply.”
Verify token details before swap
“Before I swap into this token, can you pull the on-chain metadata for contract 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 so I can confirm its name, symbol, and supply?”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/degen/token/metadata?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need quick, pay-per-call on-chain token metadata resolution across a wide range of blockchains (57+) without setting up your own RPC infrastructure. Ideal for DeFi agents, portfolio trackers, or token verification workflows that need name, symbol, decimals, and supply from a contract address on demand.
Side effects
- Invalid or malformed contract address returns an error or empty response
- Contract address exists but is not a token contract (e.g. a plain wallet or non-ERC20 contract) may return null fields
- Unsupported blockchain network for the given address format
- Network congestion or RPC errors may cause timeouts
- Contract not yet indexed or deployed on a supported chain
