We use the services to validate our customers' data and generate invoices via the HTML to PDF endpoint. Works the way we want it to!
I use HTML to PDF to generate my training agreements and Invoice PDF to generate my invoices. It's really efficient and easy to use. Plus, the support service is super responsive. After using the PDF invoice API and running the generated invoice through a French-standard invoice verification tool (X), I received full validation of compliance.

APIstax is a platform that provides secure and reliable APIs for common business needs. It offers a collection of REST endpoints to handle day-to-day tasks, such as creating PDFs from HTML, generating EPC QR codes, checking VAT numbers, geocoding addresses, and loading consumer price indexes. The platform is designed to be simple, resilient, and accessible at all times, allowing developers to focus on their business logic rather than repetitive tasks.
APIstax provides a wide range of APIs for common business tasks. Have a look at the APIstax APIs page to see all APIs.
APIstax can be used with any programming language as long as REST calls are supported. You can either use one of our SDKs by simply dropping it in, or you can generate a client from the OpenAPI document and start using it in minutes. For a complete list of supported languages, see the OpenAPI Generator documentation page.
APIstax APIs are REST-based and use JSON for communication. You can either use the provided client SDKs or make direct REST API calls. The platform offers comprehensive documentation, including details about available endpoints, required parameters, and sample responses.
APIstax provides SDKs for Java, PHP, and Quarkus, but can also be used with multiple programming languages by directly calling the REST endpoints. You can also generate a client from the OpenAPI document.

If a call cannot be executed due to a server-side error, nothing will be deducted from your credits.
There are extension packages for this, so that you can acquire additional credits. You can also acquire a package to cover peaks.
To get started, sign up and create an account on the APIstax website. You will receive 100 free credits to begin using the APIs. No credit card is required for the initial free credits.
