Firebase Studio

This is a NextJS starter in Firebase Studio.

To get started, take a look at src/app/page.tsx.

Market History Scheduler

The token chart uses a server-side hourly history file (data/market-history.txt or /tmp/market-history.txt) and a daily cut at 3:00 PM America/Mexico_City. Current storage caps are symbol-based: 24 points for BTC/ETH/SOL/XRP/BNB and 8 points for USDT (128 total points max across the 6 tracked symbols per map). Sampling cadence is also symbol-based: BTC/ETH/SOL/XRP/BNB update every 1h, while USDT is bucketed every 3h.

To keep it updated without user traffic, this repo includes a GitHub Actions scheduler:

• Workflow: .github/workflows/market-history-hourly.yml
• Endpoint: /api/market/cron-sync

Required GitHub Secrets

• SITE_URL: your deployed site URL, for example https://your-domain.com
• MARKET_CRON_SECRET: shared secret used by the scheduler and the API endpoint

Required Runtime Env Vars

• COINMARKETCAP_API_KEY (or CMC_API_KEY)
• MARKET_CRON_SECRET (same value used in GitHub secret)

SEO Indexing (Google + Social)

This project now includes:

• robots.txt route (src/app/robots.ts)
• sitemap.xml route (src/app/sitemap.ts)
• Canonical/Open Graph metadata per route
• JSON-LD structured data in the root layout
• Verification meta tags via environment variables

Optional verification env vars

• GOOGLE_SITE_VERIFICATION
• FACEBOOK_DOMAIN_VERIFICATION
• PINTEREST_SITE_VERIFICATION
• FACEBOOK_APP_ID (or NEXT_PUBLIC_FACEBOOK_APP_ID)

Site URL env var (recommended)

• NEXT_PUBLIC_SITE_URL (for canonical URLs, robots host/sitemap, OG absolute URLs)
