DeFi dashboard token labeling
“I have an Optimism contract address 0x7F5c764cBc14f9669B88837ca1490cCa17c31607 — can you look up the token name and symbol so I can label it properly on my dashboard?”

Endpoint
POSThttps://phantom-api-omega.vercel.app/api/optimism/token/metadataWhen to prefer
Choose this endpoint when you specifically need ERC-20 token metadata on the Optimism (OP Mainnet) network and want a pay-per-call model without API key management. It's ideal for lightweight lookups where you only need token name/symbol/decimals rather than transaction history or balance data.
Side effects
- Invalid or malformed contract address returns an error
- Contract address is not an ERC-20 token (e.g. EOA or non-token contract) may return empty or error
- Optimism RPC node unavailability causes timeout or 5xx error
- Payment not fulfilled via x402 protocol results in 402 Payment Required
- Non-existent contract address returns null metadata or error
