# ManyLives Domain Availability Checker

> ManyLives Domain Availability Checker is a paid API for AI agents from api.manylives.me, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-10).

Checks whether up to 10 domain names are registered or available, returning registration status and expiry dates for each.

## 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 manylives-domain-availability-checker-c33aeb2d
```

Example prompt: Can you check if mybrand.com, mybrand.io, and mybrand-app.com are available to register, or if any of them are already taken?

## When to prefer this

Use this endpoint when you need a fast, pay-per-call domain availability check for up to 10 domains simultaneously without creating an account. It is well-suited for AI agents performing brand research, startup naming workflows, or monitoring competitor domain portfolios. Prefer it over full-featured registrar APIs when you only need availability and expiry data with no registration intent.

## Known failure modes

- More than 10 domains submitted — only up to 10 are supported per call
- Malformed domain string (missing TLD, invalid characters) may cause parse errors or missing results
- Network or upstream WHOIS lookup failure returning partial results
- Payment failure (insufficient USDC balance) blocks the call entirely

## How this service works

Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.

## Output

Returns a JSON array of results for each queried domain, each entry containing the domain name, a boolean indicating whether it is registered, and — if registered — an expiry timestamp in ISO 8601 format. Unregistered domains include a likely_available flag.
