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 ERC-20 token metadata for the specified Unichain contract address, typically including the token name, symbol, and decimal precision. This allows agents to humanize raw contract addresses into recognizable token identities.
Example use cases
Token symbol lookup for DeFi dashboard
“What is the name and symbol of the token at Unichain contract address 0xAbCd1234...5678? I'm building a portfolio tracker and need to label it correctly.”
Verify token decimals before swap
“Before I execute this token swap on Unichain, can you check the decimals for contract 0xDEAD...BEEF so I can format the amount correctly?”
Enrich transaction data with token info
“I have a list of Unichain contract addresses from recent transactions — can you pull the token metadata for 0xAABB...CCDD so I know what asset was transferred?”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/unichain/token/metadata?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve a raw Unichain smart contract address into human-readable token metadata (name, symbol, decimals). Prefer this over generic blockchain explorers when you need a fast, pay-per-call programmatic lookup specifically on the Unichain network without setting up your own RPC node.
Side effects
- Invalid or malformed contract address returns an error or empty response
- Contract address that is not an ERC-20 token may return null metadata or an error
- Network issues or Unichain RPC unavailability may cause timeouts
- Payment failure via x402 protocol results in 402 response and no data returned
- Non-existent contract address returns empty or error response
