Technical details
Endpoint
POSThttps://pen-inkbox402.netlify.app/api/correspondenceWhen to prefer
Choose this endpoint when you need to quickly draft structured written correspondence — emails, letters, or messages — with a specific purpose and controllable tone, especially in automated workflows where USDC pay-per-call pricing is acceptable and no persistent account setup is desired.

- Vague or ambiguous purpose may result in generic or unhelpful correspondence
- Service unavailability on Netlify hosting returns a 503 error
