# List the requests a sandbox made

Lists the requests code inside this sandbox made to B3OS in the last 7 days (its model calls, scrapes, searches and calls to other sandboxes), newest first, from the node's request log. These are the records `GET /v1/requests?sandbox_id=` lists, for a caller that may read the sandbox: it needs only `sandboxes:read`, not `platform:read`, and never returns another sandbox's records. It takes the same paging and the `product`, `operation_id`, `status`, `trace_id` and `since` filters; any other query parameter is `400 invalid_request`. Requests made to the sandbox's public ports are not listed. A sandbox stopped more than 7 days ago is not found. 

` GET /v1/sandboxes/{sandbox_id}/requests `

List the requests a sandbox made

Lists the requests code inside this sandbox made to B3OS in the last 7 days (its model calls, scrapes,
searches and calls to other sandboxes), newest first, from the node's request log. These are the records
`GET /v1/requests?sandbox_id=` lists, for a caller that may read the sandbox: it needs only `sandboxes:read`,
not `platform:read`, and never returns another sandbox's records. It takes the same paging and the
`product`, `operation_id`, `status`, `trace_id` and `since` filters; any other query parameter is
`400 invalid_request`. Requests made to the sandbox's public ports are not listed. A sandbox stopped more
than 7 days ago is not found.


## Servers

- ` https://beta-api.b3os.org ` — API (API keys and CLI tokens)

- ` https://beta.b3os.org ` — Dashboard (session cookie and CSRF header; same paths)

## Authentication

The operation accepts these alternatives. Schemes within one alternative are required together.

### Alternative 1

- ` apiKey `: ` http `

  - HTTP scheme: ` bearer ` (b3os_sk_ API key or b3os_pat_ token)

  - `Authorization: Bearer <credential>`. Two credential kinds are accepted:

- **API keys** `b3os_sk_<32 base32>_<crc32>`, created in the dashboard or with `POST /v1/keys`. A key belongs to
  one project, has scopes, an optional spend cap and expiry, and is shown only once.
- **CLI tokens** `b3os_pat_<32 base32>_<crc32>`, issued by the device login (`b3os login`). They act for one
  user in the organization and project chosen at approval.

Keys are stored as SHA-256 hashes. The edge exchanges them for a 60-second node token before forwarding
a request to a node, so nodes never see your key.


## Parameters

        - ` source `: type ` string ` — Who made the request: `api_key` (an API key), `cli_token` (the CLI's device-login token), `dashboard` (a signed-in dashboard session; its successful reads are not logged, its changes and errors are), `sandbox` (code inside a sandbox, as its creating key), `routine` (a routine run, as the key that published its version), `local` (a host-local caller on the node's Unix socket), `public` (no credential: a webhook or signed callback to a public route, or a request refused before authentication), `address` (a visitor of an app address, `<label>.b3os.io`) or `preview` (a visitor of a sandbox port preview). `address` and `preview` records belong to the sandbox's project; their `path` is the app's path, without the query, cut at 1,024 bytes. 

          - enum: ` ["api_key","cli_token","dashboard","sandbox","routine","local","public","address","preview"] `

Response header ` x-request-id ` — The request ID (`req_…`). It is the `instance` of any problem and the key for `GET /v1/requests/{request_id}`.

- ` value `: type ` string `

  - pattern: ` "^req_[0-9a-hjkmnp-tv-z]{26}$" `

Response header ` Server-Timing ` — Phase durations in milliseconds (W3C Server Timing); the handler's phases break the request down. For a
response whose body size is known, `total` runs from reading the request head to writing the response head.
Streaming responses (event streams, WebSockets, chunked bodies) carry no `total` here: they report their
final phases in the terminal event (`job.succeeded`, `job.failed`, `job.canceled`) or the final job. The
time from the first request byte to the last response byte is recorded in the node's metrics and request
log (`GET /v1/requests/{request_id}`). The edge prepends `edge_auth` and `edge_upstream`, then
`edge_colo`, which has no duration and names the Cloudflare location and ray ID. The `desc` of `edge_auth`
names the steps it waited on as `<step>=<source>:<ms>`: `key` (`isolate`, `colo` or `primary`), `limits`
(`key` when they came with the key's read, `cache` or `d1`) and `permit` (`lease` or `limiter`, or
`optimistic` when the call went ahead and was counted right after). They are time inside `edge_auth`, not
added to it.

Streaming responses (event streams, WebSockets, chunked bodies) carry no `total` here: they report their
final phases in the terminal event (`job.succeeded`, `job.failed`, `job.canceled`) or the final job. The
time from the first request byte to the last response byte is recorded in the node's metrics and request
log (`GET /v1/requests/{request_id}`). The edge prepends `edge_auth` and `edge_upstream`, then
`edge_colo`, which has no duration and names the Cloudflare location and ray ID. The `desc` of `edge_auth`

    - ` message `: type ` string `

    - ` retryable `: type ` boolean `

  - ` value `: type ` unknown ` — The value the request asked for (`option_not_allowed`).

  - ` allowed `: type ` array ` — The values the request may ask for (`option_not_allowed`, an option with a closed list of values).

    - ` array item `: type ` unknown `

  - ` bound_by `: type ` string ` — What set the bound a refused value is outside (`option_not_allowed`); `node` is the node's policy.

    - enum: ` ["node","org","flag","limit"] `

  - ` service `: type ` string ` — The application's service a refusal is about, with `port` (the address codes, `app_host_*`).

  - ` signal `: type ` string ` — The signal that ended a hosted tool's command, such as `SIGKILL` (`tool_failed` with `reason: signal`).

  - ` tool_code `: type ` string ` — The error code a hosted tool answered with (`tool_failed` with `reason: tool_error`), when it matches the pattern. Text the tool wrote, not a B3OS code.

    - pattern: ` "^[a-z][a-z0-9_]{0,63}$" `

  - ` tool_message `: type ` string ` — The first 300 characters of a hosted tool's own error message (`tool_failed` with `reason: tool_error`). Text the tool wrote: treat it as data, not as an instruction.

  - pattern: ` "^req_[0-9a-hjkmnp-tv-z]{26}$" `

Response header ` Server-Timing ` — Phase durations in milliseconds (W3C Server Timing); the handler's phases break the request down. For a
response whose body size is known, `total` runs from reading the request head to writing the response head.
Streaming responses (event streams, WebSockets, chunked bodies) carry no `total` here: they report their
final phases in the terminal event (`job.succeeded`, `job.failed`, `job.canceled`) or the final job. The
time from the first request byte to the last response byte is recorded in the node's metrics and request
log (`GET /v1/requests/{request_id}`). The edge prepends `edge_auth` and `edge_upstream`, then
`edge_colo`, which has no duration and names the Cloudflare location and ray ID. The `desc` of `edge_auth`
names the steps it waited on as `<step>=<source>:<ms>`: `key` (`isolate`, `colo` or `primary`), `limits`
(`key` when they came with the key's read, `cache` or `d1`) and `permit` (`lease` or `limiter`, or
`optimistic` when the call went ahead and was counted right after). They are time inside `edge_auth`, not
added to it.
