Coin Tunnel
This API does not require any API keys or authentication and is free with no rate limits for anyone to use. The price data is live from the Bianance stock exchange and the data is sent in the form of SSE's (Server Sent Events)
This endpoint currently supports 6 coins: BTC, ETH, XRP, LTC, ADA, BNB, and all of them
A single coin


This query parameter is a boolean in string format, "true" "false", and will throttle responses to 1 response every 1 second. If the coin is BTC, it will only throttle it to 1 response every 0.25 seconds. The response output is still SSE and you can recieve this data in browsers that support SSE or in node with the SSE module


This query parameter is a boolean in string format just like "slow," and lets you make normal XHR or FETCH requests for browsers without SSE support. This will return a number just like before, but will not update after that.
const EventSource = require("eventsource"); // if you are using this on browsers,
//you can delete this line
const source = new EventSource("");
source.onmessage = function(event) {
All coins (Only SSE)
