Output formats

Modes

$ beam --format <mode> ...

Mode	When to use
default	Interactive terminal use. Color, spinners, friendly errors.
json	Scripting, agent loops, anything piped into jq.
yaml	Same data as JSON, YAML-encoded.
markdown	Markdown table output for some commands.
compact	Single-line, minimal text.
quiet	Print only the essential value — e.g. just a tx hash. Ideal for shell pipelines.

Examples

$ beam --format json balance
$ beam --format yaml chains list
$ beam --format markdown privacy incoming list
$ beam --format quiet transfer alice.eth 0.01
$ beam --format compact txn 0xabc...

Side effects on other output

• In default mode, RPC-backed commands show a loader spinner while requests are in flight. Press Ctrl-C during a read-only RPC loader to cancel the in-flight request.
• Non-interactive update notices are only printed in default output mode and use the cached update status instead of waiting on GitHub.
• Successful write commands print the confirmed transaction hash and block in every mode so you can verify the result immediately. Interrupted waits print the submitted hash regardless of mode.

Color

$ beam --color auto      # default
$ beam --color always
$ beam --color never

Beam writes color codes when the destination is a terminal. Override the heuristic with --color.

In the REPL, the chain segment of the prompt is tinted per network brand in color-capable terminals — Payy networks use #E0FF32.
