MCP serverDocs & knowledge

shotanvil lets your AI capture screenshots and generate PDFs from web pages and HTML. Once added, your AI can turn online content or HTML into finished images and documents on demand. An API key or x402 is required, as keyless access is disabled.

Available today. Use it from your connected AI after setup.

After adding it, set up an API key or x402 since it cannot be used without one. You can find usage examples in the repository at github.com/Psykepro/shotanvil-examples.

Then ask your AI: use shotanvil-examples

What your AI can do with it

  • Capture screenshots of web pages
  • Render HTML into images
  • Generate PDF documents from web pages or HTML

From the project's README

As published by psykepro/shotanvil-examples in README.md.

Usage examples and a live-synced OpenAPI spec copy for the shotanvil screenshot API — 1 screenshot = 1 request, a free tier that's actually free, from $9/mo.

Base URL: https://api.shotanvil.com

Access paths

GET /take and POST /render-html accept three access paths, checked in this order:

  1. x402 — send an X-Payment header (pay-per-call, no signup, testnet-settled).
  2. API key — send X-Api-Key: <key> or ?access_key=<key>.
  3. Keyless — no credential, IP-rate-limited, only when the operator has keyless access enabled.

An invalid API key always fails with 401 and never falls through to keyless, even when keyless is enabled — a typo'd paying key never silently downgrades to a lower tier.

Get an API key at shotanvil.com.

Quickstart

Take a screenshot:

curl "https://api.shotanvil.com/take?url=https://example.com" \
  -H "X-Api-Key: $SHOTANVIL_API_KEY" \
  -o screenshot.png

Get text + metadata as JSON instead of raw bytes:

curl "https://api.shotanvil.com/take?url=https://example.com&response_format=json" \
  -H "X-Api-Key: $SHOTANVIL_API_KEY"

Render inline HTML:

curl -X POST https://api.shotanvil.com/render-html \
  -H "Content-Type: application/json" \
  -H "X-Api-Key: $SHOTANVIL_API_KEY" \
  -d '{"html": "<html><body><h1>Hello</h1></body></html>"}' \
  -o out.png

More runnable examples: examples/curl.sh, examples/node/screenshot.mjs.

Common GET /take parameters

ParamTypeNotes
urlstring, requiredTarget page URL, http/https only.
formatstringpng (default), jpeg, webp, or pdf.
full_pageboolCapture the full scrollable page height, not just the viewport.
viewport_width / viewport_heightint320–3840 / 240–2160.
cache_ttlintSeconds to cache this exact render, 0–86400.
freshboolBypass the cache read for this request.
block_adsboolBlock ad-network requests via an EasyList-derived blocklist.
block_cookie_bannersboolInject a CSS kill-list that hides common cookie-consent banners.
dark_modeboolEmulate prefers-color-scheme: dark before navigation.
response_formatstringbinary (default) returns raw bytes; json wraps image (base64) + extracted text/metadata.

Full parameter reference, request/response schemas, and every field's worked example live in openapi.json — open it in any OpenAPI viewer (e.g. editor.swagger.io) for the browsable version.

Rate limits

Each API key has a per-second rate limit and a daily call cap. GET /usage reports the current key's usage for the day. Exceeding either returns 429 with a retry_after_s field.

Keeping openapi.json in sync

openapi.json in this repo is a point-in-time copy, fetched from the live GET https://api.shotanvil.com/openapi.json endpoint — it is not hand-written and will drift as the API evolves.

Before relying on it for anything beyond casual browsing, or before any future update to this repo, re-fetch and diff:

curl -sS https://api.shotanvil.com/openapi.json -o /tmp/openapi.latest.json
diff openapi.json /tmp/openapi.latest.json

If they differ, review the diff, replace openapi.json with the fresh copy, and commit — do not hand-edit openapi.json directly.
