For Agents
Generate PDF documents from HTML templates or XSL-FO, concatenate multiple PDFs, convert pages to images, and overlay text onto existing PDF files.
Use for: I need to generate a PDF from an HTML template, I want to create a PDF from an XSL-FO template, Convert a PDF page to an image for thumbnail display, Concatenate three PDF documents into one file
Not supported: Does not handle PDF parsing, OCR, data extraction, or form filling - use for PDF generation from templates and basic utility operations only.
PdfBroker.io API generates PDF documents from HTML (via wkhtmltopdf and WeasyPrint engines), XSL-FO templates with optional XSLT transforms, and provides utilities for concatenating multiple PDFs, converting PDFs to images, and writing text strings onto existing PDF pages. The API uses OAuth 2.0 client credentials authentication and returns generated files as downloadable binary responses.
Install Jentic One Beta
Connect the PdfBroker.io API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the PdfBroker.io API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fpdfbroker.io%2Fpdfbroker" | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fpdfbroker.io%2Fpdfbroker" | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
Capabilities
What an agent can do with PdfBroker.io API.
Generate PDF documents from HTML using wkhtmltopdf rendering engine
Generate PDF documents from HTML using WeasyPrint rendering engine
Render XSL-FO templates into PDF with full formatting support

Use Cases
Patterns agents use PdfBroker.io API for, with concrete tasks.
★ HTML to PDF Report Generation
Generate professional PDF documents from HTML templates with CSS styling. PdfBroker offers two rendering engines: wkhtmltopdf (POST /api/pdf/wkhtmltopdf) for webkit-based rendering with JavaScript support, and WeasyPrint (POST /api/pdf/weasyprint) for CSS3-compliant rendering with better print media support. Both accept HTML content and return the generated PDF as a binary download, enabling automated report, invoice, and certificate generation.
Generate a PDF invoice from HTML content via POST /api/pdf/wkhtmltopdf with the HTML body containing styled invoice data and return the PDF binary
XSL-FO Template Rendering
Render complex documents from XSL-FO templates for enterprise document generation workflows. POST /api/pdf/xslfo accepts XSL-FO markup and produces formatted PDF output. POST /api/pdf/xslfowithtransform first applies an XSLT stylesheet to transform XML data into XSL-FO, then renders the result. This enables data-driven document generation from XML sources with full typographic control.
Submit an XSL-FO template via POST /api/pdf/xslfo and return the rendered PDF document for a structured report layout
PDF Assembly and Modification
Combine multiple PDF files and overlay text content for document preparation workflows. POST /api/pdf/pdfconcat merges multiple PDFs in order. POST /api/pdf/pdfwritestring places text at specific X/Y coordinates on existing pages for stamping dates, reference numbers, or approval text. POST /api/pdf/pdftoimage converts pages to images for preview generation.
Concatenate a cover page PDF and a report body PDF via POST /api/pdf/pdfconcat, then write 'APPROVED' at coordinates (400, 50) on page 1 via POST /api/pdf/pdfwritestring
AI Agent Document Generation via Jentic
AI agents use the PdfBroker API through Jentic to generate PDF documents from HTML or XSL-FO templates without managing OAuth token flows. Agents search by intent, receive typed schemas for generation operations, and execute with Jentic handling the client_credentials token exchange and injection. This enables automated document generation for invoices, reports, and certificates.
Search Jentic for 'generate PDF from HTML', load the schema for POST /api/pdf/wkhtmltopdf, and execute with HTML content to produce a downloadable PDF

Why Jentic?
What agents get from Jentic-routed access to this vendor.
Setup
Wiring the PdfBroker.io API by hand means running the OAuth 2.0 client_credentials exchange at login.pdfbroker.io/connect/token, refreshing the token, and choosing between the wkhtmltopdf, weasyprint, and XSL-FO renderers yourself. Through Jentic you install once, import PdfBroker.io from the API Directory, store the client credentials once, and your agent calls it.
Permission scoping
PdfBroker.io carries its content and rendering options in the request body, so scope the agent by the operations it needs, such as generating a PDF with wkhtmltopdf or converting a PDF to an image. You choose that set, so operations like concatenation or string writing are not included unless you add them.
Credential isolation
Your PdfBroker.io OAuth client credentials are stored once, encrypted, by your own Jentic One instance, which runs the token exchange and injects the bearer token at execution time. They never enter the agent's prompt, logs, or context.
Intent-based discovery
Agents search Jentic by intent such as 'generate a PDF from an HTML template', and Jentic returns the matching PdfBroker.io operation with its input schema specifying content format and rendering options so the agent calls the right endpoint without reading the reference docs.

FAQs
Specific to using PdfBroker.io API through Jentic.
What authentication does the PdfBroker.io API use?
The PdfBroker.io API uses OAuth 2.0 with the client_credentials grant type. You exchange your client ID and secret for an access token at https://login.pdfbroker.io/connect/token with scope 'pdfbroker', then include the token in the Authorization header. Through Jentic, this token flow is handled automatically.
What is the difference between wkhtmltopdf and WeasyPrint engines?
POST /api/pdf/wkhtmltopdf uses a WebKit-based renderer that supports JavaScript execution and browser-like rendering. POST /api/pdf/weasyprint uses a CSS3-compliant renderer optimized for print media queries and paged media standards. Choose wkhtmltopdf for dynamic content and WeasyPrint for precise print layouts.
What are the rate limits for the PdfBroker.io API?
PdfBroker.io applies per-token rate limits based on your subscription plan. Standard plans support up to 50 PDF generations per minute. XSL-FO rendering with XSLT transforms may take longer per request due to processing complexity.
How do I generate a PDF from HTML through Jentic?
Search Jentic for 'create PDF from HTML template', load the schema for POST /api/pdf/wkhtmltopdf, and execute with your HTML content in the request body. Jentic handles the OAuth token exchange and returns the generated PDF binary for download or storage.
Can I add text to an existing PDF?
Yes. POST /api/pdf/pdfwritestring accepts an existing PDF and writes text at specified X/Y coordinates on a given page. This is useful for adding stamps, dates, reference numbers, or approval text without regenerating the entire document.
Can I limit what my agent is allowed to do with the PdfBroker.io API?
Yes. Because you run Jentic One yourself, your own rules decide which PdfBroker.io operations the agent can call, so you can allow just HTML-to-PDF generation with wkhtmltopdf or WeasyPrint and rendering PDF pages to images. Operations like concatenating PDFs or writing text strings onto existing pages stay out of reach unless you add them to the agent's allowed set. Your OAuth client credentials are held by your Jentic One instance and injected at call time, so the agent only ever exercises the operations you permit.
