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 Citrea contract address, including fields such as token name, symbol, and decimal precision. Useful for identifying and enriching token information in DeFi applications, wallets, or analytics dashboards.
Example use cases
Identify unknown Citrea token
“I have this contract address on Citrea: 0xabc123... — can you tell me what token it is, its symbol, and how many decimals it uses?”
DeFi dashboard token enrichment
“For my portfolio tracker, fetch the token name and symbol for each of these Citrea contract addresses so I can display them properly.”
Verify token contract details
“Before I swap, can you confirm what token is at Citrea contract 0xdeadbeef... and what its decimals are so I get the amount right?”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/citrea/token/metadata?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need token metadata (name, symbol, decimals) for a contract deployed on the Citrea blockchain. It is purpose-built for Citrea and avoids the overhead of multi-chain aggregators. Choose this over generic blockchain explorers when you need a lightweight, pay-per-call programmatic lookup within an automated agent workflow.
Side effects
- Invalid or malformed contract address returns an error or empty response
- Contract address does not exist on Citrea — returns not found or null metadata
- Contract is not a standard token contract (e.g. no ERC-20 interface) — metadata fields may be missing
- Network congestion or RPC issues may cause timeouts
- Payment failure via x402 protocol prevents the call from completing
