HTML to PDF Evidence Renderer

Renders each HTML document or permitted public URL to a hashed, print-pinned PDF evidence artifact: page count, resource-failure ledger, input+output SHA-256, final URL, and an honest COMPLETE / PARTIAL usability label. Deterministic settings, no login or cookies.

What you submit

sources — html strings or permitted public urls. Each item is either an inline HTML document (recognized by a leading '<' or a data:text/html URL) or a permitted public http(s) URL. URL items pass the per-origin runtime gate (robots + SSRF) before any fetch. Per item ONE hashed PDF artifact (stored in the run key-value store) with pinned print settings, page count, resource-failure list, input+output SHA-256, final URL, and an honest COMPLETE / PARTIAL label. Deterministic fonts, bounded resources, no login/cookies. A PARTIAL render bills ONLY when the artifact is a valid, openable PDF of at least one page; a render that fails to produce a usable PDF, or a blocked/unreachable URL, never bills.

The runtime source gate (per submitted target)

You choose the targets, so the source contract is enforced at run time — for every URL-mode item (inline HTML is rendered locally and is not fetched) — per origin, before any page is read:

• robots.txt fetched once per origin and honored; no robots / 404 = permitted, a disallowed path or an unavailable/forbidden robots file = BLOCKED.
• SSRF guard — every host is resolved and must be public; private, loopback, link-local, reserved and cloud-metadata addresses are refused before a socket opens.
• HTTP — 403 / 429 / 5xx = BLOCKED; DNS / timeout / connection faults = UNREACHABLE.

A BLOCKED or UNREACHABLE target is delivered as an unbilled status row — never a broken-site verdict, and never charged.

Output & billing

One row per item. A render bills once if and only if it produced a valid, openable PDF of at least one page. COMPLETE = valid PDF with zero resource failures; PARTIAL = valid, openable, paginated PDF that had one or more resource failures (a missing image/font) — still genuinely usable, so it bills. A render that never produced an openable PDF is labelled UNUSABLE and never bills; a blocked or unreachable URL never bills. Push-then-charge: every row is delivered before its charge, so a billing hiccup can only ever undercharge.

Pricing

Event	Price	When
apify-actor-start	$0.02	once when the run starts (reserved; never charged in code)
pdf_render_check	$0.05	once per usable PDF artifact — COMPLETE or PARTIAL (UNUSABLE / blocked / unreachable never bill)

Volume tiers reduce the per-verdict price as usage grows: $0.05 → $0.045 → $0.04 → $0.0335.

Why this and not the obvious alternative

a hashed, print-pinned PDF evidence artifact per HTML/URL with an honest COMPLETE/PARTIAL usability label and a resource-failure ledger — not a screenshot API and not an unbounded website-to-PDF crawler.
