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 structured on-chain metadata for the specified Soneium token contract, typically including the token name, symbol, decimal precision, and possibly total supply or other standard ERC-20/ERC-721 fields as available on-chain.
Example use cases
DeFi dashboard token enrichment
“I have a list of Soneium contract addresses from our DeFi dashboard — can you pull the token name and symbol for the contract at 0x1234abcd5678ef on Soneium so I can display it properly?”
Token legitimacy check before swap
“Before I do this swap, can you fetch the on-chain metadata for this Soneium token contract 0xdeadbeef0001 — I want to confirm the name and decimals match what the project claims?”
Wallet portfolio labeling
“I see an unknown token in my Soneium wallet at contract address 0xaabbccdd1122 — can you look it up and tell me what token it is and how many decimals it uses?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/soneium/token/metadataWhen to prefer
Choose this endpoint when you specifically need token metadata from the Soneium network and want pay-per-call pricing via x402 without an API key subscription. Prefer it over general block explorers when integrating programmatically into an agent workflow that needs structured JSON metadata output for Soneium tokens.
Side effects
- Invalid or malformed contract address returns an error response
- Contract address not deployed on Soneium returns empty or not-found result
- Non-token contract address (e.g. a multisig wallet) may return incomplete metadata
- Network congestion or RPC issues may cause timeouts
- Payment failure via x402 prevents request from being fulfilled
