# Token Holder Concentration Analyzer

> Token Holder Concentration Analyzer is a paid API for AI agents from vit-tu-ma-production.up.railway.app, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Analyzes token holder concentration for a given contract address, returning top-10 holder percentage, total holder count, deployer wallet retention, and whale concentration risk flags to assess rug-pull risk.

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 token-holder-concentration-analyzer-93d8150c
```

Example prompt: Before I buy this token, can you check the holder concentration risk for contract address 0xabc123... on Ethereum — specifically the top-10 holder percentage, deployer retention, and any whale concentration flags?

## When to prefer this

Use this endpoint when you need to quickly assess whether a token's ownership is dangerously concentrated among a few wallets before executing a trade, or when evaluating rug-pull risk specifically through holder distribution metrics. Prefer this over general token screeners when you need specific holder-level data including deployer retention and top-10 concentration percentages across EVM chains and Solana.

## Known failure modes

- Invalid or unsupported token contract address returns error
- Unsupported chain name returns validation error
- Token with no on-chain holder data returns empty or null response
- Rate limiting or payment failure results in 402 or 429 error
- Network timeout for slow-indexing chains

## How this service works

Token holder concentration analysis: top-10 holder percentage, total holder count, deployer wallet retention, and whale concentration risk flags. Essential rug-pull risk signal for AI trading agents. Supports EVM chains and Solana.

## Output

Returns top-10 holder percentage share, total holder count, deployer wallet token retention amount/percentage, and boolean or scored whale concentration risk flags indicating potential rug-pull danger for the queried token on the specified chain.
