## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.001 USDC), no-signup onboarding message generation for a specific employee role and company. It is ideal for automating HR welcome workflows, building onboarding pipelines, or generating personalized greetings at scale without requiring OAuth or account creation. Prefer alternatives if you need highly customized tone controls, multi-language output, or integration with an HR platform's native templates.

## Known failure modes

- Missing required 'role' or 'company' field returns a validation error
- Empty or whitespace-only strings may be rejected due to minLength:1 constraints
- Payment failure via x402 protocol results in 402 response before generation occurs
- Overly long inputs (>200 chars) for role or company are rejected by schema validation
