POSThttps://api.fastapi.online/generate-email-templateWhen to prefer
Choose this endpoint when you need a quick, AI-generated email template scaffold without signing up for a full email marketing platform. It is particularly useful for developers or agents building transactional email flows who want a ready-made starting point for a specific email type (welcome, receipt, reset, etc.) and prefer pay-per-call crypto billing with no account setup.
Side effects
- Empty or too-short purpose string (below 2 characters) returns a validation error
- Purpose string exceeding 2000 characters is rejected
- Vague or ambiguous purpose may result in a generic or unhelpful template
- Payment failure or insufficient USDC balance blocks the request (x402 protocol)
- Service downtime on self-hosted infrastructure may cause timeouts or 5xx errors
