Technical details
Endpoint
POSThttps://stableemail.dev/api/subdomain/inbox/create?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically provision a new receiving email inbox on a pre-purchased StableEmail subdomain. Prefer this over the subdomain purchase endpoint (Buy) when the subdomain already exists and you just need a new mailbox. Ideal for applications that need to dynamically create per-user or per-purpose email addresses at scale.
Side effects
- Subdomain not owned or not verified — returns authorization or ownership error
- Inbox name already exists on the subdomain — returns conflict error
- Insufficient USDC balance to cover $0.25 creation fee — returns payment failure
- Invalid inbox name format (special characters, too long) — returns validation error
- DNS or SES verification not yet complete for subdomain — returns status error
