# 47620.xyz Base ERC-20 Whale & Activity Radar

> 47620.xyz Base ERC-20 Whale & Activity Radar 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, 24-hour trading volume, and trade counts as an activity proxy for a Base network ERC-20 token, honestly disclosing that on-chain holder lists are unavailable via 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 47620-xyz-base-erc-20-whale-activity-radar-a648156e
```

Example prompt: Pull the whale and activity radar for the Base ERC-20 at address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — I want to see the DEX liquidity, 24-hour volume, and trade counts.

## When to prefer this

Choose this endpoint when you need a quick, honest activity signal for a Base ERC-20 and understand that true holder counts are unavailable via keyless RPC. It is purpose-built for Base network tokens and explicitly avoids fabricating holder data, making it more trustworthy than services that guess at holder counts. Prefer it over a full token due-diligence endpoint when you specifically need DEX liquidity and volume metrics as whale/concentration proxies without the overhead of a complete safety audit.

## Known failure modes

- Invalid or non-ERC-20 contract address returns an error or empty data
- Token with zero DEX presence returns null or zero values for all activity metrics
- Network congestion on Base may cause stale or delayed data
- Newly deployed tokens with no DEX pairs yet may return no liquidity data
- Address is a wallet, not a token contract — endpoint may return empty or error

## How this service works

Concentration / activity radar for a base 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 figures, 24-hour trading volume, and trade counts for the specified Base ERC-20 token as activity proxy signals, along with a clear holdersSource disclosure explaining that on-chain holder lists are not available via keyless RPC. No holder numbers are fabricated.
