Solid compilation here. I’d add the Discord API which has been incredibly useful for automated notifications and community management workflows. Also worth mentioning the Google Sheets API - sounds basic but it’s surprisingly powerful when you need to dump data or create simple dashboards without setting up complex databases. Been running several workflows that pull metrics from various sources and compile them into sheets for quick reporting. The Telegram Bot API is another underrated one for instant alerts and simple command interfaces. Have you experimented with any of the newer AI vision APIs like GPT-4 Vision? They integrate well with n8n for document processing workflows.

Nice work putting this together. One thing I noticed missing from your payment section is the PayPal API which has been rock solid for automating invoice generation and payment tracking in my workflows. The Twilio API deserves a mention too - incredibly reliable for SMS notifications and voice calls when you need immediate alerts. For anyone dealing with file management, the Dropbox and Google Drive APIs are essential, especially when combined with document processing workflows. The HubSpot API has also been a game changer for marketing automation beyond what ActiveCampaign offers. Weather APIs like OpenWeatherMap might seem niche but they’re surprisingly useful for location-based automation triggers. Have you run into any rate limiting issues with the social platform APIs? Some of them can be pretty restrictive for high-volume workflows.
