Crypto Tracker

Track cryptocurrency prices, set price/percentage alerts, and search coins using the free CoinGecko API (no API key required).

Quick Commands

Check Prices

# Single coin
uv run {baseDir}/scripts/crypto.py price bitcoin

# Multiple coins
uv run {baseDir}/scripts/crypto.py price bitcoin ethereum solana

# With more details (market cap, volume)
uv run {baseDir}/scripts/crypto.py price bitcoin --detailed

Search Coins

# Find coin ID by name/symbol
uv run {baseDir}/scripts/crypto.py search doge
uv run {baseDir}/scripts/crypto.py search cardano

Manage Alerts

# Set price threshold alert
uv run {baseDir}/scripts/crypto.py alert <user_id> bitcoin above 100000
uv run {baseDir}/scripts/crypto.py alert <user_id> ethereum below 3000

# Set percentage change alert (24h)
uv run {baseDir}/scripts/crypto.py alert <user_id> bitcoin change 5    # ±5%
uv run {baseDir}/scripts/crypto.py alert <user_id> solana drop 10      # -10%
uv run {baseDir}/scripts/crypto.py alert <user_id> ethereum rise 15    # +15%

# List user's alerts
uv run {baseDir}/scripts/crypto.py alerts <user_id>

# Remove an alert
uv run {baseDir}/scripts/crypto.py alert-rm <alert_id>

# Check all alerts (for cron/heartbeat)
uv run {baseDir}/scripts/crypto.py check-alerts

Coin Aliases

Common symbols are automatically resolved:

btc → bitcoin
eth → ethereum
sol → solana
doge → dogecoin
ada → cardano
xrp → ripple
dot → polkadot
matic → polygon
link → chainlink
avax → avalanche-2
ltc → litecoin

Alert Types

Type	Example	Triggers When
`above`	`alert user btc above 100000`	Price >= $100,000
`below`	`alert user eth below 3000`	Price <= $3,000
`change`	`alert user btc change 5`	24h change >= ±5%
`drop`	`alert user sol drop 10`	24h change <= -10%
`rise`	`alert user eth rise 15`	24h change >= +15%

Cron Integration

Check alerts periodically (e.g., every 15 minutes):

uv run {baseDir}/scripts/crypto.py check-alerts --json-output

Returns triggered alerts with user IDs for notification.

Data Storage

Alerts stored in {baseDir}/data/alerts.json with:

Per-user alert tracking
Cooldown between repeat notifications (default: 1 hour)
Last triggered timestamp

Notes

CoinGecko free tier: ~10-30 requests/minute (no API key needed)
15,000+ coins supported
Use --json-output flag for machine-readable output
