Crypto Volume Anomaly Scanner — Pump Detection for the Top 50 Coins

Unusual volume is the earliest public footprint of a pump: trading activity spikes while price hasn't moved yet. This actor scans the top 50 cryptocurrencies by 24h volume and ranks them by volume-to-market-cap ratio — surfacing coins trading far more heavily than their size justifies. Live market data, structured JSON, ready for trading bots, alert pipelines, and dashboards.

Two Modes

Full market scan (leave input empty) — returns all 50 coins, sorted by volume/market-cap ratio, most anomalous first. $0.01 per scan.

Single-token analysis (set symbol) — deep-dives one coin and adds an anomaly_level rating: LOW (ratio ≤ 2%), MODERATE (2–5%), HIGH (5–20%), CRITICAL (> 20%). $0.005 per analysis.

Input

{ "symbol": "BTC" }

Field	Type	Default	Description
symbol	string	(empty)	Optional ticker (BTC, ETH, SOL…). Empty = full 50-coin scan.

Example Output — full scan (one item per coin, 50 items)

{
  "symbol": "PEPE",
  "price": 0.0000121,
  "change_24h": 18.4,
  "volume": 2841000000,
  "market_cap": 5090000000,
  "vol_mcap_ratio": 55.81
}

Example Output — single-token analysis

{
  "found": true,
  "token": {
    "symbol": "BTC",
    "price": 67412.0,
    "change_24h": -1.2,
    "volume": 28400000000,
    "market_cap": 1330000000000,
    "vol_mcap_ratio": 2.14,
    "anomaly_level": "MODERATE"
  }
}

If the token isn't in the top 50 by volume, you get { "found": false, "symbol": "XYZ", "message": "Token not in top 50 by volume." } — you're still only charged the $0.005 analysis event.

How to Read the Ratio

vol_mcap_ratio = 24h volume ÷ market cap × 100. Large caps normally sit at 1–5%. A small cap at 30–60% means its entire market cap is churning every couple of days — the signature of coordinated buying, a listing event, or a pump. The scan doesn't tell you which; it tells you where to look first.

Use Cases

• Trading-bot input — schedule a scan every 15 minutes via Apify Schedules, feed the top 5 ratios into your strategy, act on CRITICAL single-token confirmations.
• Alerting — wire the actor to Slack/Discord through Apify integrations; get pinged when any coin crosses your ratio threshold.
• Screening & research — a $0.01 scan replaces manually eyeballing 50 volume charts. Export to CSV and track ratio history over days to spot building momentum.

Run It From Code

from apify_client import ApifyClient

client = ApifyClient("YOUR_API_TOKEN")

# Full market scan
run = client.actor("cryptosignals/crypto-signals").call(run_input={})
for coin in client.dataset(run["defaultDatasetId"]).iterate_items():
    if coin["vol_mcap_ratio"] > 20:
        print(f"{coin['symbol']}: ratio {coin['vol_mcap_ratio']}% — price {coin['price']}")

Pricing

Event	Price	When
Full market scan	$0.01	Once per empty-input run (50 coins included)
Single-token analysis	$0.005	Once per run with symbol set

Plus standard Apify platform micro-fees (actor start $0.00005/GB, $0.00001/dataset item). A daily scan costs about $0.31/month.

Data Source & Limits

Live market data covering the top 50 coins by 24h volume, refreshed on every run. Coins outside the top 50 return found: false in single-token mode. This is a market-activity scanner, not financial advice — anomalous volume is a starting point for research, not a buy signal.
