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 metadata about a token deployed on the Polygon network, typically including the token name, symbol, decimal precision, and other on-chain contract metadata associated with the provided contract address.
Example use cases
DeFi token identification on Polygon
“I have a Polygon contract address 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619 and I need to know what token it is — can you get the name, symbol, and decimal precision for it?”
Portfolio tracker token enrichment
“I'm building a portfolio tracker and need the full metadata for the USDC token on Polygon — the contract is 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174. What are its name, symbol, and decimals?”
Smart contract audit token lookup
“While auditing this Polygon smart contract at 0x0d500B1d8E8eF31E21C99d1Db9A6444d3ADf1270, I need to quickly confirm what token it represents and its decimal places — can you fetch the on-chain metadata?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/polygon/token/metadata?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, pay-per-call token metadata lookups on the Polygon network without managing your own RPC infrastructure or API keys. It is well-suited for agents that need to enrich blockchain data on demand, especially in workflows involving DeFi token identification, portfolio tracking, or smart contract analysis on Polygon specifically.
Side effects
- Invalid or malformed contract address returns an error
- Contract address exists but is not a standard token contract (e.g., NFT or non-ERC-20) may return incomplete metadata
- Non-Polygon addresses (e.g., Ethereum mainnet) will not resolve correctly on this endpoint
- Payment failure via x402 results in HTTP 402 and no data returned
- Network timeouts or RPC node unavailability may cause transient errors
