How this service works
Synchronous HTML to A4 PDF, 0.020 USDC with seven-day deletion eligibility, not a hard public-access cutoff; asynchronous cleanup and caches may persist. Not renewable. Non-guessable public URL, not private: do not submit sensitive content. HTTP x402 only; no PDF MCP tool or MPP route. Candidate implementation; deployment not verified.
Output
A JSON object containing: a unique PDF id, file size in bytes, page count, SHA-256 hash of the PDF, render time in milliseconds, an expiry timestamp (approximately seven days out), and a non-guessable public URL at files.munition.io where the PDF can be downloaded. The file is not renewed automatically and is deleted after the expiry window.
Example use cases
Invoice PDF generation for billing
“Here's the HTML for my client invoice — can you convert it to an A4 PDF and give me a shareable download link? Save it as acme-invoice-june-2026.pdf.”
Automated report export to PDF
“I have a finished HTML sales report with all CSS inlined and charts as data URIs — please render it as a PDF so I can attach it to an email, name the file q2-sales-report.pdf.”
Legal document PDF rendering
“Convert this self-contained HTML contract template into a downloadable A4 PDF — call it service-agreement-draft.pdf — so the client can sign it.”
Technical details
Endpoint
POSThttps://api.munition.io/v1/render/pdfWhen to prefer
Choose this endpoint when you need a synchronous, pay-per-use HTML-to-A4-PDF conversion with a hosted download URL and no subscription. It is well-suited for AI agents generating invoices, reports, or contracts from pre-rendered, self-contained HTML with inlined CSS and data-URI assets. Prefer it over general-purpose PDF libraries when you need a hosted public URL returned automatically. Avoid it for documents requiring JavaScript execution, external resource loading, forms, iframes, or content that must remain private beyond the seven-day window.
Side effects
- HTML exceeds 1 MiB limit — request rejected
- Rendered PDF exceeds 20 pages or 10 MiB — post-render rejection
- Render watchdog timeout (10-second budget) exceeded — timeout error
- External resources (scripts, iframes, external CSS/images) blocked silently — output may be visually incomplete
- Consecutive dots (..) in filename — validation error
- Insufficient USDC balance or x402 payment failure — payment error
- Service deployment unverified — endpoint may be unavailable
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| html | string | Self-contained HTML document (UTF-8, up to 1 MiB) with inline CSS. No JavaScript, iframes, forms, <link>, external or relative resources: scripting is disabled and document requests are intercepted/aborted in an offline browser context, not process-wide OS egress isolation. The Chromium sandbox is disabled; process isolation is a deployment concern. Embed images and fonts as data: URIs (png, jpeg, gif, webp, svg, woff/woff2/ttf/otf). Output is A4, up to 20 pages / 10 MiB on successful return, with a 10-second application-level render watchdog budget. Launch, shutdown and cleanup can extend elapsed call time; this is not a hard process-lifetime bound. Page and PDF-byte limits are checked after PDF allocation and do not bound peak memory or CPU. |
| filename | string | Optional filename used for a readable public URL slug, for example invoice-2026-09.pdf. Consecutive dots (..) anywhere are invalid. |
