Endpoint
POSThttps://prime-api-seven.vercel.app/api/ai/cover-letterWhen to prefer
Choose this endpoint when an agent needs to generate a job-specific cover letter on demand without managing API keys, paying per call in USDC via x402 on Base. Useful for career assistant agents, job application automation workflows, or resume tools that need a quick AI-written cover letter without a long-term API subscription.
Side effects
- Empty or vague query yields a generic, non-personalized cover letter
- Missing job title or company name results in placeholder-filled output
- Overly long input may be truncated or produce incomplete output
- Service returns 402 if payment in USDC on Base is not provided
- Generic API error response if the backend AI model is unavailable
