LinkModel API Documentation

Use --json for scripts and agents:

lkm image "a red panda" --json
lkm video status <task_id> --wait --json
lkm doctor --json

In JSON mode, stdout contains exactly one JSON line. Human-readable logs go to stderr.

Create Now, Poll Later

Use --no-wait to create a task and return immediately:

lkm image "a product photo" --no-wait --json
lkm video "a cinematic product orbit" --no-wait --json

Store the returned task_id, then resume polling later:

lkm image status <task_id> --wait --json
lkm video status <task_id> --wait --json

Set LINKMODEL_API_KEY in your CI secret store, then run CLI commands without writing a local config file:

lkm auth status --json
lkm image "a product photo" --json

Code	Meaning
`0`	Success.
`1`	Task failed, task cancelled, download failure, or API/network error.
`2`	Usage error, invalid parameters, missing API key, or unknown command.
`3`	Authentication failed.
`4`	Polling timed out; the server task keeps running.
`130`	Interrupted with `Ctrl-C`; the server task keeps running.

Handle 4 and 130 as resumable states when your workflow stores the task_id.
