Side-by-side comparison of two NFT collections across six due-diligence metrics — supply, holders, holder ratio, top-10 concentration, wash-trading score, and activity trend — with a per-metric winner verdict.

## 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-comparator-517b5e20
```

Example prompt: Can you compare the NFT collections at contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D (Bored Ape Yacht Club) and 0xb47e3cd837dDF8e4c57F05d70Ab865de6e193BBB (CryptoPunks) on Ethereum and tell me which one wins on each metric — holders, wash-trading, concentration, and activity trend?

## When to prefer this

Use this endpoint when an agent must make a binary recommendation between exactly two NFT collections and needs objective, multi-dimensional data to justify the choice. It is ideal for due-diligence workflows, NFT advisor agents, and portfolio screening tools where supply health, holder decentralization, and wash-trading risk all matter. Prefer this over single-collection lookup endpoints when the comparison verdict itself (winner per metric) is the output that drives the decision.

## Known failure modes

- Invalid or non-existent contract address returns error or empty metrics
- Unsupported chain value (anything other than ethereum or base) returns validation error
- Rate limiting or payment failure (x402) if USDC balance is insufficient
- Contract addresses that are not NFT collections may return null or incomplete metrics
- Wash-trading or activity data unavailable for very new or illiquid collections

## How this service works

Compare any two NFT collections on the full due-diligence metric set: supply, holders, holder ratio, top-10 concentration, wash-trading score and activity trend — with a winner per metric. The head-to-head an agent runs before recommending one collection over another. Use this when an agent needs to two collections side-by-side, metric by metric verdicts.

## Output

A structured comparison object showing both collections' values for supply, holder count, holder ratio, top-10 holder concentration, wash-trading score, and activity trend, plus a winner designation for each metric indicating which collection performs better on that dimension.
