Example use cases
Identify unknown Linea token
“I found this contract address on Linea: 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 — 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 for these Linea token contracts — can you fetch the name, symbol, and decimals for 0xc2132D05D31c914a87C6611C10748AEb04B58e8F?”
Validate token before swap
“Before I swap, can you confirm the token details for contract 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 on Linea so I know I have the right asset?”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/linea/token/metadataWhen to prefer
Use this endpoint when you need fast, on-demand token metadata specifically for the Linea blockchain network. Prefer it over generic multi-chain explorers when you know the target chain is Linea and want a simple pay-per-call lookup without API key management.
Side effects
- Invalid or malformed contract address returns an error
- Contract address does not exist on Linea — returns null or not found
- Contract is not a standard ERC20/token contract — metadata fields may be absent
- Payment failure via x402 protocol prevents the call from completing
- Network timeout or RPC node unavailability on Linea
