What's changed in Fyxvo.

Webhooks: POST /v1/projects/:id/webhooks — create HTTP callbacks for funding.confirmed, apikey.created, apikey.revoked, balance.low, and project.activated events. HMAC-SHA256 signatures on every payload. Test endpoint included.

Team collaboration: invite team members by Solana wallet address, view pending invitations, accept or remove members from project settings.

Public project pages: enable a public URL at /p/[slug] showing aggregate request volume and latency. No authentication required. Badge generator for GitHub READMEs.

Enterprise waitlist: /enterprise page with contact form for dedicated capacity inquiries. Form submissions stored in database.

API Explorer in docs: interactive try-it panel embedded in the documentation page. Live requests against the real API with JWT auto-injection.

Developer playground: schema panel showing response structure per RPC method, compare mode for standard vs priority side-by-side latency comparison, shareable URLs with method and params encoded in query string, and one-click example fill.

Notification preferences: per-user toggles for all seven notification types. Email address storage (delivery coming soon).

Assistant rate limit display: progress bar showing hourly message usage in the AI assistant.

Activity log: timeline of key actions per project — API key events, webhook changes, member activity.

README badge: embeddable SVG badge from /badge/project/[slug] showing live gateway latency. 5-minute CDN cache for GitHub's image proxy.

System announcements: admin-configurable banner that appears on the dashboard for all authenticated users.

Health endpoint: improved /health with per-dependency response times for database, Redis, and Solana RPC.

AI Developer Assistant: streaming chat assistant powered by Claude claude-sonnet-4-20250514 at /assistant. Answers Solana development questions, generates code examples in JS/TS/Python/Rust, explains Fyxvo pricing and architecture, and uses project context for personalized answers.

Project Templates: three project creation templates — blank, DeFi trading, and data indexing. Templates pre-configure suggested funding amounts and show template-specific getting-started guides.

Usage Widget: public embeddable widget at /widget/project/[id]. Shows requests today, average latency, and gateway status. Supports light and dark themes via ?theme=. Auto-refreshes with ?live=true.

Onboarding Flow: five-step welcome modal for new users explains the full setup flow. Dismissal state persists to the database.

Analytics Cost Breakdown: analytics page shows estimated SOL spend for the selected time range, classified by method tier (standard vs compute-heavy).

Pricing Page Overhaul: live SOL/USD pricing from CoinGecko with interactive cost estimator, volume discount tiers, and revenue split display.

Service Health Timeline: status page shows 48-entry uptime history per service as color-coded timeline blocks.

Connection Quality Indicator: sidebar indicator polls API health every 30 seconds and shows fast/normal/slow/offline status with tooltip showing exact response time.

Service Worker: offline support via service worker. Serves cached pages when the user is offline and auto-restores when connection returns.

Network Stats API: public GET /v1/network/stats returns total requests served, projects, API keys, and SOL fees collected. Powers the live stats strip on the landing page.
