## 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 stabledomains-domain-search-d2e03b8e -d '<json body>'
```

Example prompt: Can you check if 'coolstartup.xyz' is available to register on StableDomains — I want to search without creating any account and I'll pay in USDC on Base.

## When to prefer this

Choose this endpoint when you need to check domain availability without creating an account, prefer paying per-query in USDC on Base rather than subscribing to a service, or are building a crypto-native workflow where accountless domain search is desirable.

## Known failure modes

- Payment not received or insufficient USDC balance causes request to fail
- Invalid domain name format returns an error
- Network issues on Base blockchain delay payment confirmation
- Unsupported TLD returns no results or an error
- Rate limiting if micropayment mechanism is abused

## How this service works

Domain registration via micropayments. No accounts. Pay USDC on Base.

## Output

Returns availability status for the queried domain name, along with relevant registration options or pricing, after a $0.01 USDC micropayment on Base is processed via x402 protocol.
