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 SEI contract, typically including token name, symbol, decimal places, and other contract-level properties stored in the token's metadata fields.
Example use cases
Identify unknown SEI token contract
“I found this contract address on SEI and I don't know what token it is — can you fetch the name, symbol, and decimals for 0x4A2b...F9c1?”
DeFi dashboard token enrichment
“I'm building a portfolio tracker and need the token name and symbol for this SEI contract address: sei1qpqprqrds... — can you pull that metadata?”
Verify token details before trading
“Before I swap into this token, can you confirm the name, symbol, and decimal precision for the SEI contract address sei1xyz987...?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/sei/token/metadataWhen to prefer
Use this endpoint when you specifically need token metadata (name, symbol, decimals) for a contract deployed on the SEI blockchain. Prefer this over generic blockchain explorers when you need programmatic, pay-per-call, low-latency access without API key registration. Best suited for agents performing automated token lookups, portfolio enrichment, or pre-trade verification on SEI.
Side effects
- Invalid or malformed contract address returns an error response
- Contract address not deployed on SEI network returns not-found or empty metadata
- Non-token contract address (e.g. a plain smart contract) may return incomplete or missing metadata fields
- Network congestion or RPC unavailability may cause timeout or 5xx errors
- Payment failure via x402 protocol results in 402 response blocking the request
