🟢check_pdf_accessibility(url, pdf_base64, language)
Validate a PDF against PDF/UA-1 with veraPDF and list every failed rule (rule id, description, number of failed checks, link to a plain-language explanation). The automatic fix is then run on the file and validated again, so the result also says which failures the fix removes and whether the file then passes — measured on this file, not estimated. Give either 'url' (a public http(s) address of the PDF, max 10 MB) or 'pdf_base64'. The file is not stored and the fixed file is not returned here.

"type": "object",
"properties": {
"url": {
"type": "string",
"description": "Public http(s) URL of the PDF (max 10 MB)."

"pdf_base64": {
"type": "string",
"description": "The PDF file encoded as base64, if it is not online (max 10 MB decoded)."
},
"language": {
"type": "string",
"description": "Document language the fix sets when the PDF declares none (BCP 47, e.g. en-US, de-DE, fr-FR). Default en-US."
}
}
}🟢explain_pdfua_rule(rule)
Explain a veraPDF PDF/UA-1 rule by id (clause-test, e.g. 7.1-3, 7.3-1, 7.18.5-1, 7.21.4.1-1): what it checks, the veraPDF error message, whether the automatic fix removes it and how to fix it in the authoring tool.
