47620.xyz Polygon Contract Inspector is a paid API for AI agents from 47620.xyz, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).
Checks whether a Polygon address is a smart contract, returns its bytecode size, and retrieves ERC-20 token metadata (name, symbol, decimals) if applicable.

How this service works
Whether a polygon address is a contract, its bytecode size, and (for ERC-20s) name/symbol/decimals.
Output
Returns a boolean indicating whether the address is a contract, the bytecode size in bytes, and — if the contract implements ERC-20 — the token name, symbol, and decimal precision.
Example use cases
Validate token contract before swap
“Before I swap into this token at 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 on Polygon, can you confirm it's actually a deployed ERC-20 contract and tell me its name and symbol?”
Distinguish contract from wallet address
“I have this Polygon address 0xaB5801a7D398351b8bE11C439e05C5B3259aeC9B — is it a smart contract or just a regular wallet? And if it's a contract, what's its bytecode size?”
Fetch ERC-20 decimals for price calculation
“I need the decimals for the ERC-20 token at Polygon address 0x0d500B1d8E8eF31E21C99d1Db9A6444d3ADf1270 so I can correctly format the token amounts in my calculation.”
Technical details
Endpoint
GEThttps://47620.xyz/x/polygon/contract/:address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly determine whether a Polygon address is a deployed smart contract and optionally retrieve ERC-20 token metadata in a single call. Prefer it over generic Polygon RPC calls when you want a structured, pre-parsed response without manually calling eth_getCode and multiple ERC-20 view functions yourself.
Side effects
- Invalid or malformed Polygon address returns an error or empty result
- Address exists but is an EOA (not a contract) — bytecode size is 0 and ERC-20 fields are absent
- Contract exists but does not implement ERC-20 interface — name/symbol/decimals will be null or missing
- Network congestion or RPC node issues may cause timeouts
- Address of a self-destructed contract may return empty bytecode
