#Real-world use cases

#Automated blog content

Challenge: Generate SEO-optimized blog posts at scale
Solution: Use generate with keywords and optimization settings

POST /v1/article/generate
{
  "brief": "Write about cloud cost optimization strategies",
  "niche": "technology",
  "tone": "professional",
  "style": "guide",
  "optimization": "seo",
  "keywords": {
    "whitelist": ["cloud costs", "AWS", "cost optimization"],
    "blacklist": ["cheap", "free trial"]
  },
  "length": 2000
}

#Editorial quality assurance

Challenge: Review articles before publication
Solution: Validate content quality and compliance

// Generate article
POST /v1/article/generate {...}

// Validate before publishing
POST /v1/article/validate {
  "article_content": "Generated article content...",
  "details": {
    "niche": "technology",
    "expected_length": 2000,
    "tone": "professional"
  }
}

// Check validation_passed before publishing

#Best practices

  1. Write detailed briefs: More context = better articles. Include key points to cover.
  2. Use appropriate lengths: 1000-2000 words for blog posts, 2500-5000 for guides
  3. Match tone to audience: Professional for B2B, casual for consumer content
  4. Validate before publishing: Use the validate endpoint for quality assurance
  5. Leverage keywords wisely: Whitelist for must-include, blacklist for brand safety
  6. Set human_like to high: For content that needs to pass AI detection
  7. Handle long responses: Generation can take 10-30 seconds for long articles

#API Changelog

2025-01-21
v1.0 Launch: Article API released with generate and validate endpoints. Support for multiple formats, tones, styles, and SEO optimization.
