# 47620.xyz Polygon Contract Inspector

> 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.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability 47620-xyz-polygon-contract-inspector-35947cf9
```

Example prompt: Can you check if the Polygon address 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619 is a smart contract, and if it's an ERC-20 token, tell me its name, symbol, and decimals?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
