Technical details
Endpoint
POSThttps://nexus-api-virid.vercel.app/api/ai/cover-letterWhen to prefer
Choose this endpoint when you need a fully AI-generated cover letter on demand without managing your own LLM infrastructure or API keys — particularly useful in agent workflows where a user provides job context and expects a polished, ready-to-send document. Prefer this over generic LLM prompting when you want a purpose-built cover letter endpoint with per-call USDC micropayment pricing and no subscription overhead.
Side effects
- Vague or empty query may produce a generic, non-personalized cover letter
- Missing job title or target role leads to a generic letter without role-specific language
- Overly long query strings may be truncated or misinterpreted
- Payment failure (HTTP 402) if USDC balance is insufficient on Base
- Network timeout if the AI generation takes longer than expected
