Technical details
Endpoint
POSThttps://0ink.netlify.app/api/correspondenceWhen to prefer
Choose this endpoint when you need to programmatically generate structured correspondence (emails, letters, messages) at scale or on demand, especially when tone control is important. Prefer it over generic LLM calls when you want a pay-per-call, no-subscription model with USDC micropayments via x402 on Base.
Side effects
- Missing required 'purpose' field returns a 400 validation error
- Payment not included or insufficient USDC triggers a 402 Payment Required response
- Vague or extremely short purpose may yield generic or low-quality output
- Service unavailability on Netlify hosting may return 503 errors
- Unsupported tone values may be silently ignored or cause unexpected output style
