## 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 karma-domains-traffic-checker-a7bf5276
```

Example prompt: Can you check the traffic and SEO backlink metrics for 'vintagewatch.com' on Karma.Domains? I want to know if it's worth buying as an expired domain.

## When to prefer this

Use this endpoint when you need to quickly evaluate a single specific domain's traffic and backlink quality before purchasing it as an expired domain. It is ideal for due diligence on auctioned or dropped domains and complements broader domain search endpoints when you already have a candidate domain in mind.

## Known failure modes

- Domain not found in database — returns empty or null metrics
- Invalid domain format — missing or malformed 'domain' query parameter causes 400 error
- Domain has no indexed traffic data — metrics may be zero or absent
- Payment failure — x402 payment of 1.5 USDC not completed, returns 402 error
- Rate limiting or quota exceeded — too many requests in a short period
