+# Crypto Pro App API
+
+Reverse-engineered API from Crypto Pro iOS/macOS app.
+
+Public endpoints, no authentication required.
+
+## Dictionary Endpoint
+
+Provides reference data for all assets, exchanges, and client configuration.
+
+This is the lookup table to convert between asset IDs, symbols, and names.
+
+Should be cached locally as it rarely changes.
+
+```bash
+curl "https://cdn.cryptopro.app/data/dictionary.json"
+```
+
+**Sample response**:
+```json
+{
+  "a": [
+    [6, "BTC", "Bitcoin", 3, "f09428"],
+    [7, "ETH", "Ethereum", 3, "797faf"],
+    [8, "XRP", "XRP", 3, ""],
+    ...
+  ],
+  "e": [
+    [1, "Yahoo Finance", 1, 3600, "yahoo.com"],
+    [2, "All Cryptos", 2, 60, "coinmarketcap.com"],

+    ...
+  ],
+  "l": [...],
+  "o": [...],
+  "u": [...],
+  "w": [...]
+}
+```
+
+**Response properties**:
+
+### `a` - Assets array
+Each asset has 5 values:
+- `[0]` - Asset ID (integer)
+- `[1]` - Symbol (string)
+- `[2]` - Full name (string)
+- `[3]` - Asset type: `1` = Fiat/Metal, `3` = Crypto
+- `[4]` - Hex color for UI (string, can be empty)
+
+### `e` - Exchanges array
+Each exchange has 5 values:
+- `[0]` - Exchange ID (integer)
+- `[1]` - Display name (string)
+- `[2]` - Exchange type: `1` = Fiat aggregator, `2` = Crypto aggregator, `3` = Spot exchange
+- `[3]` - TTL/cache duration in seconds (integer)
+- `[4]` - Data source domain (string)
+
+### Other arrays:
+- `l` - UI presets for watch lists
+- `o` - Symbol aliases mapping alternative symbols to asset IDs
+- `u` - Feature flags for client
+- `w` - Popular assets list
+
+## Query Specific Assets
+
+Get current market data for specific cryptocurrencies by their asset IDs.
+
+This is the most efficient way to track a portfolio or watchlist, returning only the data queried in a compact format.
+
+```bash
+curl "https://api.cryptopro.app/v4/markets.php?i=6,7,8&k=17231040"
+```
+
+**Response - 5 values per asset**:

+  ]
+}
+```
+- `[0]` - Asset ID (matches dictionary.json)
+- `[1]` - Current price in USD (float)
+- `[2]` - 24h change as decimal (`0.0088` = +0.88%)
+- `[3]` - 24h volume in USD (float)
+- `[4]` - Sparkline: string of digits 0-9 representing price trend
+
+## Query All Market Data
+
+Get comprehensive market data from a specific exchange/aggregator.
+
+Exchange ID (`e`) `2` uses CoinMarketCap (per `dictionary.json`'s domain field).
+
+Returns extended information including market cap, supply data, and global market statistics.
+
+Default returns ~17,000 cryptos; use `l` parameter to limit results.
+
+```bash
+curl "https://api.cryptopro.app/v4/markets.php?e=2&k=17231040"
