crawl4ai_watch_budget_add $0.00125 per call

Buy a watch budget for your team's monitors. Add Crawl4AI credits to your team's watch budget. You choose the amount; it is charged once, now, and your monitors run until it is used, then pause by themselves. Send your own purchase id as ref: a retry with the same ref adds nothing and charges nothing. (Crawl4AI · Open web & SEO data)
