I'm making an app and when the user clicks dial, instead of dialing the end user, they will dial an intermediary number which will then dial the end user.
Twilio does this, bu is too costly at $0.03/min.
Are there other APIs that offer a cheaper solution?
You mention 'when the user clicks dial', so it sounds like it's web-based... Twilio just released Twilio Client - perhaps you can use that to accomplish this at 1/4 cent per minute.
Twilio Client: https://www.twilio.com/docs/api/client
Twilio Pricing: https://www.twilio.com/pricing
The only others I know of are CallFire # $0.035 / min, and Tropo # $0.003 /min. So, nothing cheaper than I'm aware of, no.

Using free tools, how can I modify/override a server response on the user-agent/client for any http method (e.g. POST/GET/DEL regardless of whether it is a fetch/XMLHttpRequest request)?
I have tried:
Requestly browser extension, but it only handles fetch API/XMLHttpRequest requests
HTTP Tookit but it does it on the fly only for paid PRO version
Fiddler Everywhere but it needs to be bought (a trial period is not enough)

What is the difference between socketio and OPC UA and when would I choose which protocol?
Are socketio and OPC UA the same type of protocol and alternatives of each other or do they fit into different catergories.
Are there any alternatives to these protocols?
Both are quite different even if they share some features.
To be basic, those 2 are used in different roles.
Socket.IO = real-time web communication
OPC UA = industrial automation communication
Yes there is quite a lot of alternatives to those 2 protocols:
MQTT (https://en.wikipedia.org/wiki/MQTT)
Web Socket (https://en.wikipedia.org/wiki/WebSocket)
XMPP / Jabber (https://en.wikipedia.org/wiki/XMPP)
AQMP (https://en.wikipedia.org/wiki/Advanced_Message_Queuing_Protocol)

I have found the following http client so far: AsyncHttpClient, so i would to know if AsyncHttpClient really does asynchronous non-blocking IO?

I`m considering FCM to push message and have a fairly large user base, 1-2 million users using in a week. I have the following queries on the free FCM usage
The number of calls to firebase per day/week/month, is it unlimited in the free FCM usage?
Is there a limit on the concurrent calls I can make to my FCM server account?
Can the data payload exceed 4kb?
Is there a limit on the device groups that can be created?
Firebase Cloud Messaging is indeed free and unlimited. There is no documented limit on the number of calls you can make, although there are measures to protect against abuse.
Not that I know of.
Nope, the maximum message size is 4k.
There is no limit on the number of device groups that can be created (at least as far as I know).

Suppose my Skype integration wants to filter notifications for a user to messages that contain the string "server down". Is this possible?
Per default Skype for Business (=SfB) can only block URL or attachments as written here. Maybe there exist an 3rd party application which can do that, but I do not think so. Reason: The problem here is that SfB can perform peer2peer connections (see more here). That means if you and your workmade are in the same network and no firewall restricts you both and you both perform a chat together, the chat is done between both of you (without a real server connection; for more infos see the official documentation inside the 2nd link). So a 3rd party software (which might sitting on the server) will not capture that kind of information. So what you might need is a client software on every PC. But what about the mobile clients then? So I do not think that such a software exists or would be possible to build.
