# Polygon Whale Radar – ERC-20 Activity & Liquidity

> Polygon Whale Radar – ERC-20 Activity & Liquidity is a paid API for AI agents from 47620.xyz, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-02).

Returns DEX liquidity, 24h trading volume, and trade counts as an activity proxy for a Polygon ERC-20 token, honestly disclosing that on-chain holder lists are unavailable from a keyless RPC.

## 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-whale-radar-erc-20-activity-liquidity-ef67a027
```

Example prompt: Can you run a whale radar check on the Polygon ERC-20 at address 0xD6DF932A45C0f255f85145f286eA0b292B21C90B — I want to see the DEX liquidity, 24-hour volume, and trade counts to gauge how actively it's being traded?

## When to prefer this

Use this endpoint when you need a quick, honest activity snapshot for a Polygon ERC-20 — especially when you want DEX liquidity and volume data without false holder counts. Prefer this over generic blockchain explorers when you need a structured, agent-friendly response that explicitly acknowledges data limitations. Best suited for due diligence, token screening, and activity monitoring on Polygon specifically, as opposed to Ethereum mainnet or Solana equivalents.

## Known failure modes

- Invalid or non-ERC-20 contract address returns an error or empty result
- Token with no DEX listings returns zero liquidity and volume with a clear note
- Network congestion on Polygon may cause delayed data
- Address checksum errors may cause lookup failure
- Very newly deployed tokens may have no trading history yet

## How this service works

Concentration / activity radar for a polygon ERC-20. ERC-20 holder lists are NOT available from a keyless RPC, so this reports DEX liquidity, 24h volume and trade counts as an activity proxy and states holdersSource honestly. Never fabricates holder numbers.

## Output

Returns DEX liquidity depth, 24-hour trading volume, and 24-hour trade counts for the specified Polygon ERC-20 token, along with a transparent holdersSource field disclosing that exact holder lists cannot be retrieved from a keyless RPC. No fabricated holder numbers are included.
