# GET /api/v1/hosts/machines/{id}

Machine detail: compatibility findings, current offer/job, observed metrics, drain state (host owner/admin)

Operation: `getMachine`.

Machine detail: compatibility findings, current offer/job, observed metrics, drain state (host owner/admin)

Includes `telemetry`: the latest agent-reported sample plus `observed_at`, `age_s` and `boot_id`, or null when nothing was ever reported. Telemetry is evidence only and never influences admission, qualification, billing or job state. A measurement the host could not take is ABSENT from the object — it is never rendered as 0 and never carried over from an earlier sample, so a consumer must age it via `age_s` and show `unknown` when stale.

## Endpoint

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

## 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.

## Parameters

| Name | Location | Presence | Type | Description |
| --- | --- | --- | --- | --- |
| `id` | path | Required | UUID |  |

## Responses

### `200`

Machine detail.

`application/json`
| Field | Type | Presence | Description |
| --- | --- | --- | --- |
| `accepts_custom_images` | boolean | Optional | The host's opt-in to renter-supplied public images on this machine (default false). |
| `tier` | "container" / "inference" | Optional | Tier A (renter containers) or Tier B (managed inference), set at enrollment. |
| `host_mode` | object | Optional | D-22 host mode as the last heartbeat reported it; null until one does. |
| `kernel_driver_runtime` | string | Optional | Kernel/driver/runtime triple from the manifest, e.g. linux-6.8/nvidia-560.35/cuda-12.6. |
| `recent_jobs` | array of object | Optional | The machine's latest 20 rentals, newest first. ended_at is null while a rental is open. |
| `listing_blockers` | array of string | Optional |  |
| `market_price` | object | Optional | D-35 suggested listing price: the market price a renter pays for ONE of this GPU for one hour. basis amplerun = AmpleRun's own listed offers of this model (at least 3); otherwise basis reference = a hand-curated table of official public list prices, each with its page and the date it was read (upper side, p75); otherwise basis throughput = each reference row of the same class (consumer or datacenter) turned into the price giving this GPU the same tokens per dollar, from memory bandwidth (LLM token generation is memory-bound), and the p75 of those. Renters pay the listed price (the 10% commission comes out of it), so the suggestion is the market price itself. null when neither exists. A suggestion only: the host sets its own price. |
| `auto_qualify` | object | Optional | The automatic machine test: the worker queues it while the agent heartbeats, retries failures with backoff, and admits a passed machine with a listed offer. reason is set for retrying and needs_attention. |
| `telemetry` | schema | Optional |  |
