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 specified contract address on opBNB, typically including token name, symbol, number of decimals, and total supply as recorded on the blockchain.
Example use cases
Identify unknown opBNB token
“I just received a token transfer on opBNB from contract 0x1234567890abcdef1234567890abcdef12345678 — can you tell me what token it is, its symbol, and how many decimals it uses?”
DeFi dashboard token enrichment
“I'm building a portfolio tracker and need the full metadata — name, symbol, and decimals — for the opBNB token at contract address 0xDeAdBeEf000000000000000000000000DeAdBeEf.”
Verify token contract details
“Before I list this token on my DEX, can you pull the on-chain metadata for contract 0xAbCdEf1234567890AbCdEf1234567890AbCdEf12 on opBNB to confirm its name, symbol, and total supply?”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/opbnb/token/metadataWhen to prefer
Use this endpoint when you specifically need token metadata from the opBNB (BNB Chain Layer-2) network. It is purpose-built for opBNB and part of a multi-chain suite supporting 57+ networks, so prefer it over generic blockchain APIs when working with opBNB contracts specifically.
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-ERC-20 contract) may return null fields
- Contract not deployed on opBNB network returns not found
- Network congestion or RPC issues may cause timeouts
- Payment failure (x402) if USDC balance is insufficient
