Developer FAQ

Frequently Asked Questions

Technical specifications on Content Generation & Copywriting APIs latency SLAs, concurrency limits, schema validation, and billing.

Does the Content Generation API format HTML tags?

Yes! Responses include semantic HTML tags (<h2>, <h3>, <p>, <ul>, <li>) ready for immediate insertion into your CMS or database.

Can I specify custom word counts for articles?

Yes, you can pass target word_count parameters (e.g. 500, 1000, 1500) to control depth and length.

How does the API ensure meta descriptions don't get cut off on Google?

The generation pipeline strictly clamps meta titles to under 60 characters and descriptions to under 155 characters, preventing SERP ellipsis truncation.

Can I provide specific keywords to include in headings?

Yes. Supplying a target_keywords array instructs the model to strategically weave keywords into H1 and H2 tags for maximum SEO weight.

Are generated articles guaranteed to be unique?

Yes. Content is synthesized dynamically based on your unique topic and parameters rather than templated scraping.
