## How to call it through Zero

```sh
zero fetch --capability cortexcloud-nft-aggregation-endpoint-084dec4f
```

Example prompt: Can you pull aggregated NFT data for the Bored Ape Yacht Club collection — I want floor price, volume, and recent sales — paying per call with no signup needed?

## When to prefer this

Choose this endpoint when you need on-chain NFT data without registering for API keys or managing subscriptions — ideal for AI agents that pay per call in USDC on Base via x402, and when you need aggregated cross-marketplace NFT stats in a single call.

## Known failure modes

- Invalid or unrecognized collection address returns empty or error response
- Unsupported blockchain network results in no data
- Payment failure via x402 prevents call from completing
- Rate limiting if too many concurrent calls are made
- Sparse or missing metadata for newly minted or obscure collections

## How this service works

Pay-per-call on-chain data API for AI agents: token prices, risk scoring, wallet intelligence, whale alerts, balances, tx history, cross-chain comparison — evidence-backed JSON, settled in USDC on Base via x402. No API keys, no signup.

## Output

Returns a JSON object containing aggregated NFT data such as collection metadata, floor prices, sales volume, token-level ownership information, and on-chain statistics sourced across NFT marketplaces and the Base blockchain.
