Technical details
Endpoint
POSThttps://stableemail.dev/api/subdomain/buyWhen to prefer
Use this endpoint when you need to register a custom, branded subdomain on stableemail.dev for a user, agent, or application that will send and receive email under a personalized address. Prefer this over buying a full inbox (which costs $1 for 30 days) when the primary goal is a persistent custom domain identity rather than a temporary forwarding inbox.
Side effects
- Subdomain already taken — returns conflict error
- Insufficient USDC balance — payment failure
- Invalid subdomain format — returns validation error
- Subdomain contains reserved or disallowed characters — rejected
