A simpler capture workflow

Reliable visual checks start with predictable readiness. Wait for a selector, text, load state, or short delay, then capture the page or the exact component under review.

Example request

{
  "url": "https://example.com/dashboard",
  "output": "png",
  "selector": "#weekly-chart",
  "wait_for": { "selector": "#weekly-chart[data-ready=true]" }
