## When to prefer this

Use this endpoint when an agent needs to quickly generate a customized cover letter for a specific company and job title without requiring authentication or subscriptions — ideal for agentic job application workflows that pay per use via USDC x402.

## Known failure modes

- Missing required fields (company or jobTitle) returns a validation error
- Payment not sent or insufficient USDC via x402 returns a 402 Payment Required error
- Company or job title input is too vague or malformed, resulting in a generic or low-quality cover letter
- Service unavailable on Vercel deployment returns a 500 or timeout error
