How this service works
ENS name availability: Is name.eth available? Registered / grace period / available, expiry date, yearly base price and registration link. Free tier 10/day; then $0.001 via x402 (HTTP 402 + PAYMENT-REQUIRED) or X-API-Key credits. Not charged on failure. $0.001 USDC per call via x402 on Base. Run by MoneyTools.
Output
Returns the ENS name's status (available, registered, or in grace period), expiry date if registered, yearly base registration price in USD/ETH, a direct registration link, and payment metadata including whether the free tier was used or a $0.001 USDC charge was applied.
Example use cases
Pre-purchase ENS name check
“Before I try to buy it, can you check if defi.eth is available, in a grace period, or already registered — and if it's available, what does it cost per year?”
Brand launch domain research
“We're launching a new crypto project called Nexus — is nexus.eth available to register, and what's the yearly base price?”
Check expiry on existing ENS name
“Can you look up when cryptopunks.eth expires? I want to know if it's coming up for renewal soon.”

Endpoint
GEThttps://tools.moneytools.dev/v1/ens-available?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, structured lookup of ENS name availability, pricing, and expiry without integrating directly with Ethereum RPC nodes or the ENS SDK. It's ideal for agents that need to surface registration decisions to users, compare multiple names, or embed ENS checks into a broader workflow. At $0.001 per call with a free tier of 10/day, it's cost-effective for occasional to moderate usage.
Side effects
- Invalid or malformed ENS label input returns an error without charging
- Free tier exhausted (10/day) without API key or x402 payment results in HTTP 402 Payment Required
- Network/RPC issues querying ENS contracts may cause transient failures
- Names with special characters or unsupported TLDs may return an error
