What is it?

This is a service for online monitoring of parameters. It works very simply: you send HTTP requests with parameters to our server, and we display them in a convenient format on a web page. There is no registration, no payments, and no unnecessary complexity — just start sending data and view the charts.

Security

Access to modifying data is controlled using an API key, which you can generate yourself or by using the tool on our website. An API key is secret information. Anyone who knows it can modify the parameter values of your account. The API key is simply 16 random bytes.

A public address is the first 16 bytes of SHA3-256(API_KEY). Thus, each API key corresponds to a unique public address. Both the API key and the public address are encoded in Base58.

How to send metrics

To send a parameter value, you can make a regular GET request: https://gazer.cloud/set/API_KEY?/=VALUE

How to get the public address from an API key

You can use the service at https://gazer.cloud/playground to obtain the public address corresponding to a specific API key. The data you enter is not sent to the server — all operations are performed locally in your browser.

Limits

To protect against spam, there are limits on the number of requests from a single IP address. Currently, no more than 10 SET requests per second are allowed from one IP.
