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 BNB Chain (BSC) token contract, typically including the token name, symbol, number of decimals, and total supply as recorded in the smart contract.
Example use cases
Identify unknown BNB token
“I found this contract address on BNB Chain: 0x0E09FaBB73Bd3Ade0a17ECC321fD13a19e81cE82 — can you tell me what token it is, its symbol, and how many decimals it uses?”
DeFi portfolio token enrichment
“I have a list of BEP-20 contract addresses from my wallet transactions on BSC. Can you pull the token name and symbol for 0x2170Ed0880ac9A755fd29B2688956BD959F933F8 so I can label it properly?”
Verify token details before trading
“Before I swap on PancakeSwap, can you confirm the name, symbol, and total supply for the BNB Chain token at contract 0x1CE0c2827e2eF14D5C4f29a091d735A204794041?”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/bnb/token/metadata?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, pay-per-call token metadata resolution for BNB Chain (BSC) contracts without managing your own RPC node or indexer. It is ideal for agents enriching DeFi data, verifying token identities before transactions, or labeling wallet activity on BNB Chain specifically. Prefer this over generic blockchain explorers when you need programmatic, structured output at low cost.
Side effects
- Invalid or malformed contract address returns an error or empty response
- Contract address exists but is not a BEP-20 token, causing missing or null metadata fields
- Network or RPC node outages on BNB Chain may cause timeouts
- Non-existent contract address returns no metadata
- Contract does not implement standard ERC-20/BEP-20 metadata functions, resulting in incomplete data
