Frequently Asked Questions
1. What is the H2I endpoint used for?
The H2I endpoint is used to render HTML content into generated outputs through the Davix H2I API. Its core purpose is to convert HTML layouts, templates, or dynamically generated markup into image or PDF files for use in applications, websites, and automated workflows.
2. What does H2I mean?
H2I stands for HTML to Image. This reflects the original core capability of the platform: turning HTML content into image output. The platform also supports HTML-to-PDF rendering, but HTML rendering remains the defining capability of the H2I service.
3. What actions does the H2I endpoint support?
The public H2I endpoint supports two main actions: image and pdf. This allows you to use the same rendering service to generate either image output or PDF output from HTML content.
4. What kind of input does the H2I endpoint accept?
The H2I endpoint accepts structured requests that include an
actionvalue andhtmlcontent. In practice, this means you send HTML markup and request either image or PDF output, along with any relevant rendering parameters for the requested result.5. What can I build with the H2I endpoint?
The H2I endpoint is well suited for use cases such as visual report generation, automated documents, marketing assets, template-based output generation, and HTML-based PDF creation. It is especially useful when your system already generates HTML dynamically and needs to turn that content into files automatically.
6. Can I use my own HTML templates?
Yes. The H2I endpoint is designed for user-provided HTML layouts, templates, and dynamically generated markup. This makes it suitable for systems that already use HTML as their layout layer and want to generate image or PDF outputs from that content.
7. Can the H2I endpoint generate both images and PDFs from HTML?
Yes. HTML-to-image and HTML-to-PDF rendering are both central capabilities of Davix H2I, and the public H2I endpoint supports both output types.
8. Is the H2I endpoint only for developers?
No. Direct API usage is developer-friendly, but Davix H2I is designed to support a broader range of users through multiple integration paths. In addition to direct API usage, the platform also supports website and automation environments through integrations such as WordPress and n8n.
9. Can I use the H2I endpoint in automated workflows?
Yes. One of the key strengths of Davix H2I is its ability to function inside automation workflows. A system can generate HTML from data, send it to the H2I endpoint, and then use the returned image or PDF file as part of a larger automated process.
10. Can I integrate the H2I endpoint into apps, backend systems, or websites?
Yes. Davix H2I is designed to operate across a wide range of environments, including custom applications, backend services, websites, scripts, and workflow systems.
11. Do I need to build my own rendering infrastructure?
No. The H2I service is designed to give you access to rendering and processing capabilities without requiring you to build and maintain that infrastructure yourself. Its value is in making complex backend rendering available through a simple service interface.
12. How do I authenticate requests to the H2I endpoint?
You authenticate requests using your API key. The public
/v1/h2iendpoint supports standard API-key access as part of the Davix H2I public API surface.13. What does a successful H2I response return?
A successful H2I request returns a generated output URL for the rendered file. Depending on the selected action, that output will be the image or PDF file created from your HTML content.
14. Are generated H2I outputs returned as files or URLs?
Generated H2I outputs are returned through output URLs. The public output path for H2I-generated files is under
/h2i/*, and output delivery can use signed URLs depending on platform configuration.15. What happens behind the scenes when I send an H2I request?
When you send a request to Davix H2I, the rendering work is executed by the H2I engine (PixLab). Davix H2I is the product and service layer, while the H2I engine (PixLab) performs the actual backend rendering and output generation.
16. Is the H2I endpoint suitable for agencies, startups, and product teams?
Yes. Davix H2I is positioned as a backend processing service for developers, teams, businesses, startups, agencies, and automation builders who want to add media and document generation features to their systems without managing the underlying infrastructure.
17. What happens if my H2I request is invalid or unsupported?
If a request is invalid, missing required input, or exceeds supported request rules, the API returns a structured error response so your system can detect the issue and respond appropriately. For the full list of H2I-related errors, users should check the Errors and Limits section of the documentation.
18. Are there size or usage limits for the H2I endpoint?
Yes. The H2I endpoint is subject to rendering, validation, and service limits. For the latest usage rules and current limits, users should check the Errors and Limits section of the documentation.
19. What do I get when I buy access to the H2I endpoint?
