WriteText.AI API
AI-powered content generation for ecommerce

The WriteText.ai API is a cutting-edge, AI-driven solution for generating product content tailored to ecommerce. It enables deep integration of advanced copywriting, keyword optimization, and SEO automation into ecommerce platforms, PIM systems, ERP solutions, and other business applications.

Note: API access is available on the Pro and Enterprise plans only.

With this API, you can automatically generate complete, high-quality keyword-optimized product content at scale, including:

  • Product descriptions
  • Category descriptions
  • SEO meta titles & descriptions
  • Open Graph texts
  • Image alt texts

The AI adapts output to match your brand’s tone and style and supports multilingual optimization for global expansion.

Ideal for businesses that require deep integration

WriteText.AI is the perfect solution for companies needing seamless integration, whether you’re working with:

  • ERP, PIM, or proprietary ecommerce platforms
  • Automated content pipelines
  • Inventory or product database syncs
  • B2B personalization (e.g., customer-specific product text)

Use it to streamline your workflows, boost discoverability through dynamic SEO, and scale content operations with complete catalog automation.

Use cases

Automated product onboarding

When adding new products to your online store or PIM database, use the API to instantly generate all related content (long description, short description, SEO meta tags, etc.). This eliminates the need for manual copywriting – for example, as soon as you input product details (like name, features, specs), the API can return a polished product description and SEO text ready to publish. Businesses save time and ensure every product has high-quality descriptions upon launch.

Bulk catalog updates

For businesses managing large catalogs or frequent product updates, the API can generate or refresh content in bulk. For instance, if you need to update descriptions for an entire category of products, the API can generate new text for all those items in one batch. This use case is valuable during catalog migrations, seasonal updates, or SEO overhauls, allowing dozens or hundreds of product pages to be updated programmatically in a short time frame.

Integration with PIM/ERP systems

Enterprises with Product Information Management (PIM) or Enterprise Resource Planning (ERP) systems can integrate the WriteText.AI API to enhance their product data workflows. For example, when a new product record is created in the PIM, the API can automatically generate marketing copy and SEO metadata for that product, which can then be fed into ecommerce sites, catalogs, or back to the PIM system. This seamless integration ensures that even internal or custom-built systems can leverage AI-generated content without switching platforms. It’s especially useful for companies that maintain a single source of truth for product data and want to enrich it with quality descriptions and keywords.

Integration with ecommerce platforms

WriteText.ai’s API enables seamless integration with various ecommerce platforms like Amazon, eBay, Zalando, Lazada, and Shopee. This means you can automate the content generation for your product listings directly into these platforms via WriteText.ai’s API, allowing for standardized and dynamic content that fits the specific needs of your product pages, enhancing both content quality and efficiency.

This API is particularly valuable if you're managing listings across multiple channels, as it allows for flexible and rapid content generation that matches each platform's unique requirements—whether you're updating product descriptions, titles, or other details like technical specifications and benefits.

Helpful references
For e-commerce businesses that want to integrate WriteText.ai’s generated content into their existing product listings, you can use our robust API to seamlessly push dynamic product details to platforms like Amazon, eBay, Zalando, Lazada, and Shopee. Check the developer documentation for each platform to learn how to integrate WriteText.ai’s API for automatic content generation and integration with your store:

Multilingual content optimization

If your business operates across multiple regions, you can use the API to generate product content in different languages from the same source data. For instance, you could take an English product and have the API produce a German, French, or Spanish version automatically. This use case streamlines localization efforts for global ecommerce – your development team can integrate once and produce content in any supported language on demand, ensuring consistency and saving on translation costs.

Content refresh & SEO improvement

WriteText.ai doesn’t just generate content once—it keeps optimizing it over time. With the API, you can utilize the keyword optimization pipeline that starts with low-difficulty, high-volume keywords and automatically progresses to more competitive terms as your product pages gain authority.

When your site hits key ranking milestones, the API can trigger auto-regenerated content to align with new keyword targets—ensuring your product descriptions remain fresh, relevant, and search-optimized without manual input. This dynamic SEO approach helps you stay ahead of algorithm changes and competitor shifts while continuously improving your store’s visibility.

Authentication & access

Access to the WriteText.ai API is secured and requires proper authentication. Developers must have an active WriteText.ai account on a Pro or Enterprise plan to obtain API credentials.

Once you have an account with API access, you can generate your API key in the backend at https://platform.writetext.ai. All API requests must include this key for authentication (typically via an HTTP header or query parameter as specified in the documentation).

The API uses HTTPS for all communication to ensure data security. Each request you make will be validated against your account, checking your subscription status and available credit balance​. WriteText.AI operates on a credit-based model: generating content consumes credits from your account (the amount depends on the type of content generated). Ensure that your account has sufficient credits or an active plan before making requests.

Authentication example: Using the API typically involves sending your API key in the header of each HTTP request (for example, an Authorization: Bearer <Your_API_Key> header). After verifying the key, the server processes your request (such as a content-generation call) and returns the result in JSON format. If the key is missing or invalid, the API will return an authentication error.
