## 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 agenttools-nft-collection-due-diligence-report-e04b9d9c
```

Example prompt: Before I buy into this NFT collection, can you run a full on-chain due-diligence check on the Ethereum contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13d — I want to see holder concentration, any wash-trading signals, and the recent activity trend.

## When to prefer this

Use this endpoint when an agent needs a comprehensive, read-from-chain NFT collection risk assessment — particularly before facilitating or recommending a purchase. Prefer this over generic blockchain explorers when you need a pre-packaged due-diligence verdict (concentration, wash-trading, activity trend) rather than raw transaction data. Best suited for Ethereum and Base NFT collections where contract address is known.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Contract address exists but is not an NFT (ERC-721/ERC-1155) contract
- Unsupported chain parameter (only ethereum and base are supported)
- On-chain data temporarily unavailable due to node issues — may return partial data
- Rate limiting or payment failure (x402) if USDC payment not processed correctly

## How this service works

Full on-chain due-diligence report for any NFT collection: mint supply, unique holders, top-10 ownership concentration with a verdict, wash-trading indicators from transfer patterns, and recent activity trend. Read straight from the chain — the check an agent runs before its human buys. Use this when an agent needs to the Carfax for NFT collections — holders, concentration, wash signals.

## Output

A structured report containing: total mint supply, number of unique holders, a ranked list of top-10 wallet addresses by holdings with their ownership percentages, a verdict on ownership concentration risk, detected wash-trading signals derived from transfer pattern analysis, and a trend summary of recent collection activity.
