POSThttps://stable-domains-git-ben-upgrade-agentcash-r-bb6a65-merit-systems.vercel.app/api/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to check a single domain name's availability and current registration price before initiating a purchase, especially in agentic workflows that use x402 micropayment-enabled APIs on the Coinbase ecosystem.
Side effects
- Invalid domain name format returns an error
- Unsupported TLD may return unavailable or error
- Payment of $0.01 USDC required per call via x402 protocol — missing payment causes rejection
- Network or upstream registry timeout may cause delayed or failed response

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
