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 token metadata for the specified XLayer contract address, typically including the token name, symbol, number of decimals, and possibly total supply or other on-chain contract properties.
Example use cases
DeFi token identity verification
“I'm integrating with XLayer DeFi and I need to verify what token is at contract address 0xabc123... — can you get me its name, symbol, and how many decimals it uses?”
Portfolio tracker token enrichment
“I have a list of XLayer contract addresses in my portfolio and I need to know the token name and symbol for the contract at 0xdeadbeef... so I can label it properly.”
Smart contract token audit
“Before I interact with this XLayer contract at 0x9f8e7d..., can you pull its token metadata so I know what asset I'm dealing with — name, symbol, decimals, all of it?”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/xlayer/token/metadata?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need on-chain token metadata specifically for the XLayer network. It is ideal for DeFi integrations, portfolio enrichment, or token audits on XLayer where you have a contract address and need the canonical name, symbol, and decimals without building your own blockchain RPC connection.
Side effects
- Invalid or malformed contract address returns an error
- Contract address exists but is not a token contract (e.g. a plain wallet or non-ERC20 contract)
- Contract address is valid on another chain but not deployed on XLayer
- Network or RPC unavailability causes timeout
- Payment failure via x402 protocol blocks the request
