How this service works
Render a PDF. Pass `template` (one of 45 starter slugs: invoice, receipt, contract, certificate, nda, letter, report, quote, purchase-order, lease-agreement, resume, lab-report, boarding-pass, menu, bank-statement, etc.) or `html` (raw Handlebars HTML). Returns application/pdf bytes. $0.006 USDC per render, no API key, no signup. Full catalog: GET /v1/starters (free). Agent docs: https://pdfzen.site/docs/agents/tools
Output
Returns a rendered PDF binary as the response body. If `store` is true, also returns an X-Document-Id response header pointing to the stored document for later retrieval via /v1/documents/:id/download. Content-Disposition is set to the filename if provided.
Example use cases
Automated invoice generation for SaaS billing
“Create a PDF invoice for my customer 'Riverside Studios', invoice number INV-2026-007, due date March 31 2026, line items for 5 Pro seats at $49 each — use the built-in invoice template and name the file invoice-INV-2026-007.pdf.”
Certificate of completion for online course
“Render a PDF certificate of completion for a student named 'Maria Gonzalez' who finished the 'Advanced Python' course on January 15 2026 — use the certificate starter template in A4 landscape format.”
Custom NDA from bespoke HTML layout
“Generate a PDF NDA document from this HTML I've written — it has Handlebars placeholders for party names, so fill in 'BlueSky Ventures' and 'Initech LLC' as the two parties, and store the resulting PDF so I can retrieve it later.”
Technical details
Endpoint
POSThttps://api.pdfzen.site/v402/render/pdf?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically generate a polished PDF document — especially when a pre-built business template (invoice, receipt, contract, certificate, NDA, report, resume) fits your use case, saving layout work. It is ideal for AI agents that need to produce client-facing documents on the fly, charge per-render with micropayments, and optionally persist the result. Prefer it over general-purpose headless browser approaches when low latency, predictable cost ($0.006/render), and template consistency matter.
Side effects
- Missing both `template` and `html` fields — returns 400 validation error
- Invalid template slug (not in the 45 available starters) — returns 404 or 400
- Malformed Handlebars syntax in custom HTML — render fails with template error
- Payment failure (insufficient USDC balance via x402) — returns 402 Payment Required
- Invalid pageOptions format value — returns 400 schema validation error
- Template data variables missing required fields — PDF may render with empty placeholders
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| data | object | Variables for the template's Handlebars context. Shape depends on the chosen template — call GET /v1/starters/:slug to fetch the expected `sampleData` for any starter. |
| html | string | Raw Handlebars-flavoured HTML. Use only when no starter fits (one-off bespoke layouts). Prefer `template` for consistency. Either `template` or `html` is required. |
| store | boolean | When true, persist the PDF and return X-Document-Id response header for later retrieval via /v1/documents/:id/download. Default false. |
| filename | string | Optional. Sets Content-Disposition filename on the response — useful when the PDF is delivered to a browser via an HTTP intermediary. |
| template | string | Slug of a built-in starter template. 45 available; GET /v1/starters lists them all (no auth, no payment). Either `template` or `html` is required. |
| pageOptions | object | PDF page setup: format (A3/A4/A5/Letter/Legal/Tabloid), landscape, margin, scale, displayHeaderFooter. Most starters ship sensible defaults. |
