type Client

type Client struct {
	// contains filtered or unexported fields

func New

func New(apiKey string) (c *Client, err error)

New returns an instantiated Client struct.

func NewCustom

func NewCustom(args ...interface{}) (c *Client, err error)

NewCustom returns an instantiated Client struct with custom properties.

e.g. NewCustom(apiKey, apiDomain, apiVersion, &http.Client{}, time.Minute)

func (*Client) GetCurrencyInfoById

func (c *Client) GetCurrencyInfoById(id string) (result CurrencyInfoMap, err error)

GetCurrencyInfoById returns all static metadata available for one or more cryptocurrencies.

This information includes details like logo, description, official website URL, social links, and links to a cryptocurrency's technical documentation.

func (*Client) GetCurrencyInfoBySymbol

func (c *Client) GetCurrencyInfoBySymbol(symbol string) (result CurrencyInfoMap, err error)

GetCurrencyInfoBySymbol acts identically to GetCurrencyInfoById, except that it uses symbol instead of id as query parameter.

func (*Client) GetCurrencyListingsLatestAll

func (c *Client) GetCurrencyListingsLatestAll() (result []CurrencyListing, err error)

GetCurrencyListingsLatestAll acts identically to GetCurrencyListingsLatestById, except that it uses predefined values for query parameters.

func (*Client) GetCurrencyListingsLatestById

func (c *Client) GetCurrencyListingsLatestById(
	start, limit, convert_id string) (result []CurrencyListing, err error)

GetCurrencyListingsLatestById 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.

func (*Client) GetCurrencyListingsLatestBySymbol

func (c *Client) GetCurrencyListingsLatestBySymbol(
	start, limit, convert string) (result []CurrencyListing, err error)

GetCurrencyListingsLatestBySymbol acts identically to GetCurrencyListingsLatestById, except that it uses symbols for convert parameter instead of ids.

func (*Client) GetCurrencyMap

func (c *Client) GetCurrencyMap(
	lstatus ListingStatus, start, limit, symbol string) (result []CurrencyMap, err error)

GetCurrencyMap returns a mapping of cryptocurrencies to unique CoinMarketCap ids.

Per best practices it recommends to utilizing ID instead of cryptocurrency symbols to securely identify cryptocurrencies with other endpoints and in application logic.

func (*Client) GetCurrencyMapAllActive

func (c *Client) GetCurrencyMapAllActive() (result []CurrencyMap, err error)

GetCurrencyMapAllActive acts identically to GetCurrencyMap, except that it uses predefined values for query parameters.

func (*Client) GetCurrencyQuotesLatestById

func (c *Client) GetCurrencyQuotesLatestById(
	id, convert_id string) (result CurrencyQuoteMap, err error)

GetCurrencyQuotesLatestById returns the latest market quote for 1 or more cryptocurrencies.

func (*Client) GetCurrencyQuotesLatestBySymbol

func (c *Client) GetCurrencyQuotesLatestBySymbol(
	symbol, convert string) (result CurrencyQuoteMap, err error)

GetCurrencyQuotesLatestBySymbol acts identically to GetCurrencyQuotesLatestById, except that it uses symbols instead of ids.

func (*Client) GetGlobalQuotesLatestById

func (c *Client) GetGlobalQuotesLatestById(convert_id string) (result GlobalMetrics, err error)

GetGlobalQuotesLatestById returns the latest global cryptocurrency market metrics.

Use the "convert_id" to return market values in multiple fiat and cryptocurrency conversions in the same call.

func (*Client) GetGlobalQuotesLatestBySymbol

func (c *Client) GetGlobalQuotesLatestBySymbol(convert string) (result GlobalMetrics, err error)

GetGlobalQuotesLatestBySymbol acts identically to GetGlobalQuotesLatestById, except that it uses convert instead of convert_id as query parameter.

func (*Client) GetPriceConversionById

func (c *Client) GetPriceConversionById(
	amount, id, convert_id string) (result PriceConversion, err error)

GetPriceConversionById converts an amount of one cryptocurrency or fiat currency into one or more different currencies utilizing the latest market rate for each currency.

func (*Client) GetPriceConversionBySymbol

func (c *Client) GetPriceConversionBySymbol(
	amount, symbol, convert string) (result PriceConversion, err error)

GetPriceConversionBySymbol acts identically to GetPriceConversionById, except that it uses convert and symbol instead of convert_id and id as query parameters.
