# CoinMarketCap for PHP

A PHP wrapper for [CoinMarketCap Professional API](https://pro.coinmarketcap.com/api/v1)

NOTES: only FREE APIs. Check features list [here](https://pro.coinmarketcap.com/features).

## Install

```
composer require vittominacori/coinmarketcap-php
```

## Usage

### Create client

```php
$cmc = new CoinMarketCap\Api('yourApiClient');
```

## Call Cryptocurrency APIs

### map

Returns a mapping of all cryptocurrencies to unique CoinMarketCap `id`s. Per our best practices we recommend utilizing CMC ID instead of cryptocurrency symbols to securely identify cryptocurrencies with our other endpoints and in your own application logic. Each cryptocurrency returned includes typical identifiers such as `name`, `symbol`, and `token_address` for flexible mapping to `id`.

By default this endpoint returns cryptocurrencies that have actively tracked markets on supported exchanges. You may receive a map of all inactive cryptocurrencies by passing `listing_status=inactive`. You may also receive a map of registered cryptocurrency projects that are listed but do not yet meet methodology requirements to have tracked markets via `listing_status=untracked`.

Cryptocurrencies returned include `first_historical_data` and `last_historical_data` timestamps to conveniently reference historical date ranges available to query with historical time-series data endpoints. You may also use the `aux` parameter to only include properties you require to slim down the payload if calling this endpoint frequently.

Params:
+ (string) `listing_status` - Default "active" - Only active cryptocurrencies are returned by default. Pass `inactive` to get a list of cryptocurrencies that are no longer active. Pass `untracked` to get a list of cryptocurrencies that are listed but do not yet meet methodology requirements to have tracked markets available. You may pass one or more comma-separated values.
+ (integer >= 1) `start` - Default 1 - Optionally offset the start (1-based index) of the paginated list of items to return.
+ (integer [1 .. 5000]) `limit` - Default 100 - Optionally specify the number of results to return. Use this parameter and the "start" parameter to determine your own pagination size.
+ (string) `sort` - Default "id" - Valid values: "cmc_rank", "id" - What field to sort the list of cryptocurrencies by.
+ (string) `symbol` - Optionally pass a comma-separated list of cryptocurrency symbols to return CoinMarketCap IDs for. If this option is passed, other options will be ignored.
+ (string) `aux` - Default "platform,first_historical_data,last_historical_data,is_active" - Optionally specify a comma-separated list of supplemental data fields to return. Pass `platform,first_historical_data,last_historical_data,is_active,status` to include all auxiliary fields.

```php
$response = $cmc->cryptocurrency()->map(['limit' => 3]);
```

### listings/latest

Returns a paginated list of all active cryptocurrencies with latest market data. The default "market_cap" sort returns cryptocurrency in order of CoinMarketCap's market cap rank but you may configure this call to order by another market ranking field. Use the "convert" option to return market values in multiple fiat and cryptocurrency conversions in the same call.

Params: 
+ (integer >= 1) `start` - Default 1 - Optionally offset the start (1-based index) of the paginated list of items to return.
+ (integer [1 .. 5000]) `limit` - Default 100 - Optionally specify the number of results to return. Use this parameter and the "start" parameter to determine your own pagination size.
+ (integer [ 1 .. 100000000000 ]) `volume_24h_min` - Optionally specify a threshold of minimum 24 hour USD volume to filter results by.
+ (string) `convert` - Optionally calculate market quotes in up to 120 currencies at once by passing a comma-separated list of cryptocurrency or fiat currency symbols. Each additional convert option beyond the first requires an additional call credit. A list of supported fiat options can be found [here](https://pro.coinmarketcap.com/api/v1#section/Standards-and-Conventions). Each conversion is returned in its own "quote" object.
+ (string) `convert_id` - Optionally calculate market quotes by CoinMarketCap ID instead of symbol. This option is identical to `convert` outside of ID format. Ex: convert_id=1,2781 would replace convert=BTC,USD in your query. This parameter cannot be used when `convert` is used.
+ (string) `sort` - Default "market_cap" - Valid values: "name""symbol", "date_added", "market_cap", "market_cap_strict", "price", "circulating_supply", "total_supply", "max_supply", "num_market_pairs", "volume_24h", "percent_change_1h", "percent_change_24h", "percent_change_7d", "market_cap_by_total_supply_strict", "volume_7d""volume_30d" - What field to sort the list of cryptocurrencies by.
+ (string) `sort_dir` - Valid values: "asc", "desc" - The direction in which to order cryptocurrencies against the specified sort.
+ (string) `cryptocurrency_type` - Default "all" - Valid values: "all", "coins", "tokens" - The type of cryptocurrency to include.
+ (string) `aux` - Default "num_market_pairs,cmc_rank,date_added,tags,platform,max_supply,circulating_supply,total_supply" - Optionally specify a comma-separated list of supplemental data fields to return. Pass `num_market_pairs,cmc_rank,date_added,tags,platform,max_supply,circulating_supply,total_supply,market_cap_by_total_supply,volume_24h_reported,volume_7d,volume_7d_reported,volume_30d,volume_30d_reported` to include all auxiliary fields.

### quotes/latest

+ (string) `id` - One or more comma-separated CoinMarketCap cryptocurrency IDs.
+ (string) `slug` - Alternatively pass a comma-separated list of cryptocurrency slugs.
+ (string) `symbol` - Alternatively pass one or more comma-separated cryptocurrency symbols. At least one "id" or "slug" or "symbol" is required for this request.
+ (string) `convert` - Optionally calculate market quotes in up to 120 currencies at once by passing a comma-separated list of cryptocurrency or fiat currency symbols. Each additional convert option beyond the first requires an additional call credit. A list of supported fiat options can be found [here](https://pro.coinmarketcap.com/api/v1#section/Standards-and-Conventions). Each conversion is returned in its own "quote" object.
+ (string) `convert_id` - Optionally calculate market quotes by CoinMarketCap ID instead of symbol. This option is identical to `convert` outside of ID format. Ex: convert_id=1,2781 would replace convert=BTC,USD in your query. This parameter cannot be used when `convert` is used.

+ (boolean) `skip_invalid` - Default false - Pass `true` to relax request validation rules. When requesting records on multiple cryptocurrencies an error is returned if no match is found for 1 or more requested cryptocurrencies. If set to true, invalid lookups will be skipped allowing valid cryptocurrencies to still be returned.
