## Integration options

### Option 1: REST API (primary)

All endpoints below. Use the appropriate base URL for the tier.

### Option 2: CLI

```
https://github.com/coinpaprika/coinpaprika-cli
```

Crypto market data from the terminal. 12,000+ cryptocurrencies, real-time prices, OHLCV, exchanges. Free tier included.

For CLI command reference, read `references/cli-reference.md`.

### Option 3: MCP Server (for AI IDEs)

Hosted MCP server for Claude Desktop, Cursor, Windsurf, and any MCP client.

Add to `claude_desktop_config.json` or equivalent:

```json
{
  "mcpServers": {
    "coinpaprika": {
      "url": "https://mcp.coinpaprika.com/sse"
    }
  }
}
```

The hosted server needs no API key to start. It exposes 31 tools for querying coins, tickers, exchanges, OHLCV, contracts, tags, and search. Verify the count with a live `tools/list`.

GET /coins                                     # List all coins
GET /coins/{coin_id}                           # Coin details (e.g., btc-bitcoin)
GET /coins/{coin_id}/events                    # Coin events
GET /coins/{coin_id}/exchanges                 # Exchanges listing a coin
GET /coins/{coin_id}/markets                   # Trading pairs for a coin
GET /coins/{coin_id}/ohlcv/historical          # Historical OHLCV (?start, ?end, ?interval, ?limit, ?quote)
GET /coins/{coin_id}/ohlcv/latest              # Last full day OHLCV
GET /coins/{coin_id}/ohlcv/today               # Today's OHLCV (partial)
GET /coins/{coin_id}/twitter                   # DEPRECATED
```

### Tickers (price data)

```
GET /tickers                                   # All tickers (?quotes=USD,BTC)
GET /tickers/{coin_id}                         # Specific coin ticker
GET /tickers/{coin_id}/historical              # Historical ticks (?start, ?end, ?interval, ?limit, ?quote)
```

### Exchanges

```
GET /exchanges                                 # List all exchanges
GET /exchanges/{exchange_id}                   # Exchange details
GET /exchanges/{exchange_id}/markets           # Exchange markets

```
GET /contracts                                 # List contract platforms

GET /contracts/{platform_id}/{contract_address}            # Ticker by contract (301 redirect)
GET /contracts/{platform_id}/{contract_address}/historical # Historical by contract (301 redirect)
```

**Note on contract ticker/historical:** These return 301 redirects to `/tickers/{coin_id}`. The Location header may use `http://` instead of `https://`. Handle the redirect manually by reading the Location header, fixing the scheme to `https://`, and making a second request with the Authorization header.

**Verified response shapes:**
- `GET /contracts` returns a flat string array: `["btc-bitcoin", "eos-eos", "eth-ethereum", ...]`
- `GET /contracts/{platform_id}` returns: `[{"address": "0xa974...", "type": "ERC20", "id": "xin-mixin", "active": true}]`

## Common workflows

### Get Bitcoin price (free tier, no key)

```bash
curl -s "https://api.coinpaprika.com/v1/tickers/btc-bitcoin?quotes=USD" | jq '.quotes.USD.price'
```

### Get top 10 coins by market cap

```bash
curl -s "https://api.coinpaprika.com/v1/tickers" | jq 'sort_by(-.quotes.USD.market_cap) | .[0:10] | .[] | {name, symbol, price: .quotes.USD.price, market_cap: .quotes.USD.market_cap}'
```

### Historical OHLCV for ETH (30 days)

```bash
curl -s "https://api.coinpaprika.com/v1/coins/eth-ethereum/ohlcv/historical?start=2025-01-01&end=2025-01-31" | jq
```

### Search for a token

```bash
curl -s "https://api.coinpaprika.com/v1/search?q=pepe&c=currencies&limit=5" | jq '.currencies'
