Cryptocurrency Information

Returns detailed metadata and optional fiat prices for a single cryptocurrency or token. This endpoint is useful when you only need information about one specific ticker, such as btc or trc20/usdt. Values such as minimum_transaction, minimum_fee and network_fee_estimation are retrieved from the service database.

GET https://api.kingpay.online/{ticker}/info/

Replace {ticker} with the cryptocurrency/network identifier (e.g. btc, bch, bep20/usdt, trc20/usdt).

Notices

This endpoint always returns a single object describing exactly one native coin or token.
Ticker syntax follows the same rules as in other endpoints: btc, bch, ltc, and network/token combinations like bep20/usdt, trc20/usdt.
For token tickers the returned ticker field uses the full network/token format (e.g. bep20/usdt), even though the request path may be split by slashes.
If fiat prices are enabled and available, the prices object contains converted values for multiple fiat currencies, derived from the internal USD price.
If the ticker is unknown, the endpoint returns an error JSON with status: "error".
