# Live sandboxes, forkable snapshots, loop-shape counters \[rate class: sandbox_api_rps\]

`GET /preview/sandboxes`

## Request

- Base URL: `https://autoresearch.sfcompute.com`
- URL: `https://autoresearch.sfcompute.com/preview/sandboxes`
- Auth: HTTP bearer

This workspace's sandbox plane at a glance: live sandboxes (each with the snapshot it forked from and its fork depth - or `shared_base: true` and no snapshot, meaning it came from a base Autoresearch keeps warm, which is ours and cannot be forked by id), forkable snapshots, and loop-shape counters - bakes, boots (create_sandbox), fork calls, sandboxes forked, execs, voids, oom_execs, deletes. Read it to audit a loop (N samples should read as ~1 bake, N forked, few exec calls, N deletes - if bakes or boots track your sample count, switch to fork_sandbox), to find leaked sandboxes still billing, and to see voids (infrastructure failures on our side, never billed). oom_execs counts execs that hit the guest's OOM killer - your memory budget, billed; if it tracks your sample count, bake the env with more ram_gib. The counters are live process counters since this api instance started - a shape audit, not a bill; metered usage lands in get_usage with M14.

## Query parameters

- `workspace` string

## Response `200`

The capability's JSON result.

- Result: The capability's result: the same object the MCP tool returns as structuredContent. Resources carry an `object` type discriminator and an immutable id; money is integer micro-dollars in `*_usd_micros` fields.
  - `object` string: The resource type, when the result is one resource.

## Other responses

- `400`: Malformed request: bad JSON, a parameter that does not parse, or a value outside its range. Code `invalid`.
- `401`: No bearer token, or one this API cannot verify. Code `unauthenticated`.
- `403`: Authenticated, but the token's scopes or the account's role do not reach this operation. The message names the scope word to request. Code `forbidden`.
- `404`: No such route. Code `not_found`; the body names the OpenAPI document.
- `422`: A well-formed request the platform declined: no such node, a cap reached, a state that forbids the move. The message says which, and what to do instead. Code `refused`.
- `429`: Over this door's per-customer budget. Wait `Retry-After` seconds. Code `rate_limited`.
- `500`: Our fault. Retry; if it persists, quote the request-id. Code `internal`.
