Platform Update: Credit Billing for Search & Sentiment + Security Patches - 💳 Search now costs credits: The /search command is now billed at 5 credits per use, giving all users access regardless of subscription tier while ensuring fair resource allocation. - 📊 Sentiment & Visualize now cost credits: The /sentiment and /visualize commands are now billed at 50 credits per use, consistent with other AI-powered analysis commands. - 🛡️ Better error handling for Search & Sentiment: If a search or sentiment analysis fails, your credits are automatically refunded and you receive a clear, topic-specific error message instead of a generic one. - 🔒 Security dependency updates: Several underlying libraries were updated to patch known security vulnerabilities, keeping the platform safe and up to date. - 🧪 Reliability improvement: Fixed an intermittent internal test failure related to timing that occasionally caused false negatives in CI — no user-facing impact, but improves deployment confidence. backend · 16 commit(s) · 6 file(s)
