## When to prefer this

Choose this endpoint when an agent needs to programmatically generate a cover letter on behalf of a user without managing API keys, paying per call in USDC on Base via x402 protocol. Ideal for job application automation workflows where a custom letter is needed from minimal input.

## Known failure modes

- Vague or empty query string returns a generic or nonsensical cover letter
- Missing job-specific details result in overly generic output
- Payment failure (402) if USDC balance is insufficient on Base
- Rate limiting or server errors from the Vercel deployment
- Malformed request body returns 400 or an error response
