An r/Slack post described building a bot that posts YouTube video summaries. The hard part is not Slack — it is getting structured data fast enough for a real-time bot. Five search APIs ranked for Slack integration quality.
Scavio's typed JSON responses and sub-5-second latency make it the cleanest fit for Slack bots that need YouTube, Google, or Reddit data on demand.

Why Scavio Wins
- Slack bots that post YouTube summaries need transcript data. Scavio is the only API in this list that returns YouTube transcripts alongside search results.
- Tavily and Brave have faster raw response times for simple web search. If your bot only needs Google results and speed is critical, Tavily is a strong choice.
- Multi-platform under one key: a single Slack bot can search Google, pull YouTube transcripts, check Reddit threads, and look up Amazon prices without switching APIs.
- Serper's free tier (2,500 queries) is the most generous for prototyping. Build with Serper, migrate to Scavio when you need multi-platform.
- No Slack-native SDK exists for any of these. The integration pattern is the same for all: webhook → API call → format → post to channel.
