## 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 nft-collection-sales-data-lookup-840462cb
```

Example prompt: What are the recent NFT sales for the Bored Ape Yacht Club collection on Ethereum? Use the slug bored-ape-yacht-club and chain ethereum.

## When to prefer this

Use this endpoint when you need structured NFT sales data for a specific collection identified by CoinGecko slug, Magic Eden symbol, or EVM contract address, across multiple chains including Ethereum, Solana, Base, Polygon, and Bitcoin. Prefer this over general market APIs when you need pay-per-call, agent-native access via x402 micropayments without requiring API key setup.

## Known failure modes

- Invalid or unknown slug returns empty or error result
- Unsupported chain key causes validation failure
- Contract address on wrong chain returns no results
- Missing required input fields returns schema validation error
- Payment authorization failure (x402) blocks the request
- Rate limiting or network timeout causes delayed or failed response

## How this service works
