#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.

Perguntas Frequentes

Nossa API utiliza modelos de linguagem avançados, produzindo conteúdo de alta qualidade semelhante ao humano, adequado para publicação profissional.

Você pode gerar artigos de 100 a 10.000 palavras. O padrão é 1.500 palavras, ideal para posts de blog e conteúdo SEO.

Suportamos Markdown (padrão), HTML, formato JSON estruturado e texto simples.

A validação analisa legibilidade, gramática, estrutura, uso de palavras-chave, originalidade, pontuação de spam e detecção de conteúdo sensível.

Sim. Cada requisição, mesmo as que resultam em erros, consome créditos. Seus créditos estão vinculados ao número de requisições, independentemente de sucesso ou falha. Se o erro for claramente devido a um problema da plataforma do nosso lado, restauraremos os créditos afetados (sem reembolsos em dinheiro).

Contacte-nos em [email protected]. Levamos o feedback a sério—se o seu relatório de bug ou pedido de funcionalidade for significativo, podemos corrigir ou melhorar a API rapidamente e conceder-lhe 50 créditos gratuitos como agradecimento.

Depende da API e às vezes até do endpoint. Alguns endpoints usam dados de fontes externas, que podem ter limites mais rigorosos. Também aplicamos limites para prevenir abusos e manter a nossa plataforma estável. Consulte a documentação para o limite específico de cada endpoint.

Operamos com um sistema de créditos. Créditos são unidades pré-pagas e não reembolsáveis que gasta em chamadas API e ferramentas. Os créditos são consumidos por FIFO (os mais antigos primeiro) e são válidos por 12 meses a partir da data de compra. O painel mostra cada data de compra e a sua expiração.

Sim. Todos os créditos comprados (incluindo saldos fracionários) são válidos por 12 meses a partir da compra. Créditos não utilizados expiram automaticamente e são permanentemente eliminados no final do período de validade. Créditos expirados não podem ser restaurados ou convertidos em dinheiro ou outro valor. Regra de transição: créditos comprados antes de 22 de set. de 2025 são tratados como comprados em 22 de set. de 2025 e expiram em 22 de set. de 2026 (salvo indicação de expiração anterior na compra).

Sim—dentro do período de validade. Os créditos não utilizados permanecem disponíveis e são transferidos de mês para mês até expirarem 12 meses após a compra.

Os créditos são não reembolsáveis. Compre apenas o que precisa—pode sempre recarregar depois. Se um erro da plataforma causar uma cobrança falhada, podemos restaurar os créditos afetados após investigação. Sem reembolsos em dinheiro.

Os preços são definidos em créditos, não em dólares. Cada endpoint tem o seu próprio custo—veja o selo "Créditos / requisição" acima. Saberá sempre exatamente quanto está a gastar.
