How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
Output
Returns on-chain token metadata for the specified Monad contract address, typically including the token name, symbol, decimal precision, and potentially supply or other ERC-20-standard fields exposed by the contract.
Example use cases
Identify unknown Monad token
“I found this contract address on Monad — 0xabc123... — 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 name, symbol, and decimals for a list of Monad token contracts — start with 0xdeadbeef....”
Smart contract audit token check
“Before I interact with this Monad contract at 0x999fff..., can you pull its on-chain token metadata so I know exactly what asset I'm dealing with?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/monad/token/metadata?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, pay-per-call token metadata resolution on the Monad network specifically. Prefer it over general-purpose blockchain explorers when you want programmatic, structured JSON output without scraping, and when cost-per-call pricing ($0.01 USDC) is acceptable for on-demand lookups rather than bulk indexing.
Side effects
- Invalid or malformed contract address returns an error or empty response
- Contract address is not a token contract (e.g. a plain wallet or non-ERC20 contract) — metadata fields may be missing or null
- Contract does not exist on Monad network — returns not-found or error
- Network congestion or RPC unavailability may cause timeouts
- Payment not included or insufficient USDC — returns 402 Payment Required
