## 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 blockscout-multichain-nft-search-cb23d98c
```

Example prompt: Search for NFT collections matching 'Bored Ape' across all chains in the default cluster on Blockscout's multichain explorer and show me the top 10 results with their holder counts and market caps.

## When to prefer this

Use this endpoint when you need to search NFT collections across multiple blockchain networks simultaneously within a Blockscout cluster, especially when you need cross-chain coverage with metadata like holder counts, market cap, and supply. Prefer this over single-chain block explorers when the target chain is unknown or when comparing the same NFT project across networks.

## Known failure modes

- Invalid or missing cluster_id returns a 404 or error response
- Unsupported chain_id values may return empty results or validation errors
- Empty query string may return unfiltered or empty results
- Rate limiting or payment failure (x402) if the $0.012 USDC fee is not provided
- Malformed page_token causes pagination errors
- Very broad queries may return large result sets requiring multiple paginated calls

## How this service works

Explore crypto activities with Blockscout's multichain search. Find transactions, addresses, tokens, and dapps across top blockchain networks — your go-to explorer for cross-chain blockchain data

## Output

A paginated list of NFT token records, each including the token name, symbol, type, decimals, icon URL, address hash, total supply, exchange rate, holder count, circulating market cap, and chain-specific metadata. Also includes next_page_params for cursor-based pagination.
