# GET /api/v1/hosts/machines

List own machines (host owner/admin)

Operation: `listMachines`.

List own machines (host owner/admin)

Each row carries the machine's hardware specs and its current offer, so a console can render a fleet table without one detail fetch per machine. Specs are read from the same source the public catalog reads (`manifest->devices`). A spec nobody measured is `null` — never 0 and never an empty string; `ram_bytes`, `disk_bytes` and `region` are not measured anywhere today and are therefore null in practice. `current_offer` is null when the machine has no published offer version, which is a real state (a machine mid-onboarding), not a free listing.

## Endpoint

`GET https://amplerun-api.spiry.org/api/v1/hosts/machines`

## Authentication

Use the credential and scope required by this operation. For programmatic renter/host calls: `Authorization: Bearer $AMPLERUN_API_KEY`. A host-agent signature or other specialized proof is required where the description specifies it.
