List stored Carbone templates with filtering, search, and pagination. Filter by Template ID, Version ID, category, or upload origin. Use includeVersions to see the full version history of each template. Supports cursor-based pagination for large collections. Each result carries its tags: to find templates by tag, keep the results whose tags include it (list_tags lists the tags in use). Note: templates uploaded with versioning disabled appear with id = null and are identified only by their versionId — pass that versionId where a Template ID is expected (e.g. delete_template, download_template).

Convert a document to another format without storing a template. Pure conversion: no data is sent, so Carbone tags such as {d.name} are kept as written; this is also how you proof a template in another format (DOCX template → PDF, or DOCX → ODT while it stays a template). The source file can be a local file path, an HTTPS URL, or a base64-encoded string. Use render_document instead when you need data injection ({d.field} tags resolved), translations, or batch generation. Example: { "file": "/Users/me/report.docx", "convertTo": "pdf" } (a bare file name such as "report.docx" is not a path). Common conversions: DOCX → PDF (add converter: "I" for the fastest conversion), XLSX → PDF, PPTX → PDF, HTML → PDF (converter: "C" for full CSS/JS rendering), DOCX → HTML, XLSX → CSV, PDF → PNG, PPTX → PNG (first slide as image), MD → PDF.

Generate a document by merging a Carbone template with JSON data. Two modes: (1) pass templateId to use a previously uploaded template; (2) pass template (a local file path, an HTTPS URL, or a base64-encoded string) to upload and render in a single request without storing a template. Supports output format conversion, multilingual rendering, currency conversion, batch generation, and advanced PDF options (watermark, password, PDF/A). Without data, every tag resolves to empty; to keep the tags as written, pass keepTags: true (e.g. to proof a stored template), or use convert_document for a file. Async mode: pass webhookUrl. This tool then returns only Carbone's acceptance message, never the document: Carbone POSTs { "success": true, "data": { "renderId": "..." } } to the webhook, whose server downloads the document itself from GET /render/{renderId} (one-time, no auth). You cannot fetch it from here. Batch generation (batchSplitBy) is always delivered this way.

List the Carbone tags a template uses and return a sample JSON dataset matching its structure. Call it before render_document when you do not know which data a template expects. Pass exactly one of templateId (a stored template: Template ID or Version ID) or template: a local file path, an HTTPS URL, or a base64-encoded string. It runs one render on the Carbone account and discards the document. {t()} translation tags are not listed.

List all template categories currently in use in your Carbone account. Categories act like folders for organising templates (e.g. "invoices", "legal", "hr"). Use the returned names as the category filter in list_templates or upload_template.

List all tags currently used across templates in your Carbone account. Tags are free-form labels attached to templates (e.g. "sales", "billing", "v2"). To find the templates with a tag, call list_templates and keep the results whose tags include it.

Upload and store a reusable Carbone template. Once uploaded, use render_document with the returned Template ID to generate documents from it. Supports versioning: multiple versions can live under a single stable Template ID, and rendering by Template ID uses the version with the most recent deployedAt. A result deployedAt of 0 means the version is not explicitly deployed: if another version of the same Template ID is deployed, renders by Template ID keep using that one. Accepted formats: DOCX, XLSX, PPTX, ODT, ODS, ODP, ODG, HTML, XHTML, XML, SVG, IDML, Markdown, TXT, CSV, RTF and PDF (not the legacy binary DOC, XLS or PPT).

Update the metadata of ONE stored template version: name, comment, category, tags, deployment (deployedAt), scheduled deletion (expireAt), or the Template ID it belongs to (moveToTemplateId). With a Template ID, Carbone patches its currently deployed version only; with a Version ID, that exact version. Use deployedAt to choose the version used when rendering by Template ID. Returns the patched versionId and the updated fields, as echoed back by Carbone. To delete a template now, use delete_template.

Delete a stored Carbone template. Takes effect immediately: the template is no longer listed, downloadable or renderable (404); the file itself is purged after the retention delay (Carbone Cloud: 24 hours). You can delete by Template ID (removes all versions) or by Version ID (removes only that specific version). To schedule a deletion instead, use update_template_metadata with expireAt set to a future Unix timestamp.

Download the original source file of a stored Carbone template (e.g. the DOCX, XLSX, PPTX, or HTML file that was uploaded). Use this to inspect, edit, or back up a template. Pass a Template ID to download the currently deployed version, or a Version ID to download a specific version. Set sample: true to get the JSON sample dataset stored with the template instead of the template file.

Check Carbone API health and version. Returns the current API version and a status message. Useful for verifying connectivity and confirming which Carbone version is active.

Returns a summary of all Carbone capabilities: supported formats, features, tool usage examples, and links to full documentation. Call this first if you are unsure what Carbone can do.
