The server call is made anonymously.

Anonymous usage with curl

Upload and execute:

$ curl -o hello.wasm https://www.gate.computer/hello.wasm
$ curl -X PUT -H "Content-Type: application/wasm" --data-binary @hello.wasm "https://gate.computer/gate-0/module/sha256/3eebfe195ff2e6b51112137eaebad029305a18aaedd8ead4e415959b20138da3?action=call&function=greet"
hello, world

SHA-256 hash of the uploaded module contents must be included in the URL.

Executing the same module via IPFS:

$ curl -X POST "https://gate.computer/gate-0/module/ipfs/QmQV5N5LQnPV2M8TLXcfYUfW1EKiTkcZejvY3zPFMc5qhg?action=call&function=greet"
hello, world

Anonymous usage with browser

Execute by IPFS hash via browser:

https://gate.computer/ipfs/QmQV5N5LQnPV2M8TLXcfYUfW1EKiTkcZejvY3zPFMc5qhg?function=twice

Command line client with authentication support

Prebuilt binaries are available for Linux x86-64/ARM64, macOS x86-64/ARM64, and Windows x86-64/ARM64.

Alternatively, it can be built using Go:

$ go install gate.computer/cmd/gate@latest

If necessary, create an Ed25519 private key using OpenSSH authentication key utility:

$ ssh-keygen -t ed25519                    # Defaults to ~/.ssh/id_ed25519.
$ ssh-keygen -t ed25519 -f filename        # If you want to use a Gate-specific key (see below).

Manage resources bound to your public key:

$ gate gate.computer launch ./hello.wasm greet
01234567-89ab-odef-0123-456789abcdef

$ gate gate.computer io 01234567-89ab-cdef-0123-456789abcdef
hello, world

$ gate gate.computer instances
01234567-89ab-odef-0123-456789abcdef HALTED with result 0

$ gate gate.computer modules
3eebfe195ff2e6b51112137eaebad029305a18aaedd8ead4e415959b20138da3

The private key location can be overridden on the command line or in a configuration file:

$ gate -o identityfile=filename gate.computer call 3eebfe195ff2e6b51112137eaebad029305a18aaedd8ead4e415959b20138da3 greet
hello, world

$ mkdir -p ~/.config/gate
$ echo 'identityfile = "filename"' >> ~/.config/gate/client.toml
