## 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 bloomfilter-17185f3c -d '<json body>'
```

Example prompt: Register the domain 'mycoolstartup.xyz' for me and point it to IP 203.0.113.42 — no account setup, just pay with x402.

## When to prefer this

Choose Bloomfilter when you need to programmatically register a domain and configure DNS in a single API call without creating an account or providing credit card details, especially in automated or agent-driven workflows where x402 micropayments are preferred over traditional billing.

## Known failure modes

- Domain already taken — returns error indicating the domain is unavailable
- Insufficient x402 payment — returns payment error
- Invalid domain name format — returns validation error
- DNS configuration conflict — returns error if records conflict
- Network timeout during registration — returns timeout or retry error

## How this service works

Register domains and manage DNS with a single API call. No accounts or credit cards required, just x402 payments.
