veraPDF by pagespool

Check whether a PDF conforms to PDF/A, the ISO archiving standard, with veraPDF. Input: `pdf_base64` is the PDF as base64, at most 4 MB decoded; or pass the file as a download link in `file`. `profile` picks the PDF/A part and level. Returns `compliant` (true or false), `profile_name` (the profile veraPDF used), `statement`, `passed_rules`, `failed_rules` and `top_failed_rules`: up to 10 failed rules with their `id` (clause and test number), `specification`, `description` and `failed_checks`. A file that is not a PDF fails with `not_a_pdf`; an unavailable veraPDF with `engine_unavailable`. For the full report in JSON, XML or HTML, use the REST API (`POST /v1/verapdf/api/validate/{profile}`). Credits: 2 per call.

Check whether a PDF is accessible by PDF/UA, the ISO standard for accessible PDF. veraPDF checks the machine-checkable rules of PDF/UA: tags, structure, alt text present, fonts, metadata. Whether alt text or reading order make sense still needs a person. Input: `pdf_base64` is the PDF as base64, at most 4 MB decoded; or pass the file as a download link in `file`. `profile` is "ua1" or "ua2". Returns `compliant` (true or false), `profile_name`, `statement`, `passed_rules`, `failed_rules` and `top_failed_rules`: up to 10 failed rules with their `id` (clause and test number), `specification`, `description` and `failed_checks`. A file that is not a PDF fails with `not_a_pdf`; an unavailable veraPDF with `engine_unavailable`. For the full report, use the REST API (`POST /v1/verapdf/api/validate/ua1`). Credits: 10 per call.
