How this service works
817 pay-per-call APIs for AI agents. Every endpoint is POST /<name> and is payable in USDC over x402 on Base and Solana — no signup, no API key, just pay-per-call. GET https://x402.agentutility.ai/ returns the same catalog as machine-readable JSON.
Output
Returns a list of brainstormed domain name candidates, each with its slug, a human-readable rationale explaining the naming choice, a brandability score (1-10), and arrays of available and taken TLDs — plus a summary of how many candidates were returned and which TLDs were checked.
Example use cases
Startup naming session
“I'm building a paid AI utility toolkit for developers — brainstorm 10 catchy domain names for it, check .com and .ai availability, and use a technical tone so the names feel developer-friendly.”
Side project domain hunt
“I want to launch a meal-planning app for busy parents — can you suggest 6 fun, playful domain names and check if any .com, .app, or .co versions are still available?”
Agency rebranding search
“We're rebranding our luxury interior design studio — suggest 5 premium-sounding domain names with a luxury tone and check availability on .com and .studio.”
Technical details
Endpoint
POSThttps://x402.agentutility.ai/domain-suggest?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need both creative name generation AND real-time availability checking in a single call. It's ideal for product naming workflows where you want LLM-powered brandability scoring alongside actual DNS lookup results. Prefer this over generic WHOIS checkers when you need brainstorming rather than checking a specific known name, and over pure LLM prompting when you need verified availability data.
Side effects
- concept string exceeds 240 characters — returns validation error
- count × tlds.length exceeds 80 lookups — returns 400 bad request
- unsupported TLD provided (not in allowlist) — returns validation error
- LLM brainstorm timeout — may return fewer candidates than requested
- all suggested names already taken — returns candidates with empty available_tlds arrays
