## 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 polygon-erc-20-token-dossier-8db4f0a7
```

Example prompt: Give me the full token dossier for the Polygon ERC-20 at address 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 — I want the name, symbol, decimals, total supply, live price, liquidity, 24h volume, DEX pair count, and market cap all in one shot.

## When to prefer this

Choose this endpoint when you need a comprehensive Polygon ERC-20 token profile in a single API call rather than assembling data from multiple sources. It combines on-chain metadata with live DEX market data, making it ideal for pre-trade analysis, portfolio auditing, or agent-driven DeFi workflows on Polygon. Prefer it over generic blockchain explorers when you need price, liquidity, and volume alongside contract metadata without chaining multiple requests.

## Known failure modes

- Invalid or non-ERC-20 contract address returns an error or empty metadata
- Token with no DEX liquidity may return null/zero for price, volume, and pair count
- Very new or obscure tokens may lack FDV and market cap data
- Polygon RPC or pricing data source outage causes timeout or stale data
- Malformed address format (wrong length, missing 0x prefix) triggers a validation error

## How this service works

Everything about a polygon ERC-20 in one call: on-chain metadata (name/symbol/decimals/totalSupply), price, liquidity, 24h volume, DEX pair count and fdv/marketCap when available.

## Output

A single JSON response containing the token's on-chain metadata (name, symbol, decimals, totalSupply), live price in USD, total liquidity across DEX pools, 24-hour trading volume, number of active DEX pairs, and when available the fully diluted valuation (FDV) and market cap — all aggregated in one call for the specified Polygon ERC-20 address.
