## How to call it through Zero

```sh
zero fetch --capability x402-coinstats-app-6fc2dd59
```

Example prompt: Pull the CoinStats NFT collection data for the Bored Ape Yacht Club contract at 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D — I want the current floor price, trading volume, total supply, and number of holders.

## When to prefer this

Use this endpoint when you need NFT collection-level metrics (floor price, volume, supply, holders) by contract address and want data aggregated by CoinStats rather than querying raw on-chain data or a generic NFT marketplace API. Best suited for agents that already work within the CoinStats x402 ecosystem and need fast, cost-efficient per-call lookups.

## Known failure modes

- Invalid or malformed contract address returns a 400 or 404 error
- Contract address exists on-chain but is not indexed by CoinStats returns empty or not-found response
- Network or blockchain not supported returns an error
- Payment header missing or insufficient USDC balance returns 402
- Rate limiting or upstream data unavailability may cause 503 responses
