## How to call it through Zero

```sh
zero fetch --capability api-web3identity-com-32318373
```

Example prompt: What is the estimated market value of 'punk.eth'? I want to know how much it might be worth based on its length, characters, and current ENS market data.

## When to prefer this

Use this endpoint when you need a quick programmatic appraisal of an ENS .eth name before buying, selling, or negotiating. Prefer this over manual lookups or marketplace estimates when you need a structured, API-driven valuation incorporating length and character scoring alongside live market data.

## Known failure modes

- ENS name not found or invalid format — returns error or null valuation
- Name without .eth suffix may not be recognized
- Market data unavailable — estimate may be stale or missing
- Very rare or unusual character sets may produce low-confidence estimates
- Rate limiting or payment failure via x402 protocol
