Tools

Tool	What it does
render_screenshot	Renders any URL and returns the image visually — the agent can actually read the page. Supports full-page, retina 2×, dark mode, element hiding, cookie-banner blocking, iPhone/iPad/Android presets.
render_pdf	URL or raw HTML → print-ready PDF (A4/Letter/Legal, landscape, margins, header/footer with page numbers).
create_og_image	Branded 1200×630 social card, returned visually. Seven themes.
extract_page	URL → structured JSON (title, description, headings, links, images, word count) or clean Markdown — built for RAG and agent pipelines.
ai_extract	URL + natural-language prompt → structured JSON extracted by LLM.
code_image	Code snippet → macOS-window syntax-highlighted PNG.
check_usage	Remaining renders for the configured key.
workflow_create	Create a workflow — an automation that runs steps (screenshot, extract, fetch any public API, AI, email, webhook) on a schedule, when a monitored page changes, or via webhook.
workflow_list	List your workflows: trigger, steps, enabled state, last run.
workflow_run	Run a workflow immediately and report every step's result.
workflow_runs	Recent run history of a workflow.
