Compatibility with the E2B SDK

CoAI Sandbox is tested against the official SDKs e2b 2.52.0 (PyPI and npm) and the Code Interpreter SDKs e2b-code-interpreter 2.10.1 and @e2b/code-interpreter 2.8.0: the SDKs' own test suites run against a fresh CoAI Sandbox, unchanged (the e2b suites every night). Older 2.x releases are checked for the basic steps (test/sdk-compat/minver).

Supported

Area	What works
Sandboxes	`Sandbox.create` (template, `timeout`, `metadata`, `envs`), `connect`, `kill`, `set_timeout`, `get_info`, `Sandbox.list` with filters, order and pagination
Commands	`commands.run` (foreground and background), streaming output, `send_stdin`, `kill`, `list`, `connect`; PTY
Files	read, write, write many, list, exists, info, metadata, rename, remove, make directories, watch, secured access
Network	`allow_internet_access`, `network.allow_out` / `deny_out` (within your level), updating the network of a running sandbox, the traffic access token
Hosts	`get_host(port)` and the `<port>-<id>` addresses, with the access token where your level needs it
Metrics	`get_metrics` of a sandbox and the latest metrics of your sandboxes (their SDK tests join the nightly matrix with M3's beta suites)
Code Interpreter	the `code-interpreter-v1` template: `run_code` in Python, JavaScript, R, Bash and Java (its SDKs' own suites: the matrix's group 2)

Not yet (planned)

Feature	What you get today
Pause and resume (`pause`, `resume`, `connect` to a paused sandbox)	501 `not_implemented`
`lifecycle` / `autoPause`, `autoResume`, `keep_memory`	400 `unsupported_feature`
`network.httpsPorts`, `network.maskRequestHost`	400 `unsupported_feature`

Not supported

Feature	What you get
Building templates (`Template`, the E2B CLI), custom templates	501 `not_implemented`; use `base` or `code-interpreter-v1`
MCP gateway (`mcp=`)	400 `unsupported_feature`
`network.rules` (header transforms), `network.egressProxy`	400 `unsupported_feature`
Volumes (`volume_mounts`), workload identity (`iam`)	400 `unsupported_feature`
Snapshots, forks, sandbox logs and the other API routes not listed above	501 `not_implemented`
E2B access tokens (`E2B_ACCESS_TOKEN`, `Authorization: Bearer`)	401: use an API key (`E2B_API_KEY`)

Differences you may notice:

The base template has python3 but no python command.
Limits are those of your level (tiers and limits page), not E2B's Hobby or Pro limits; for now internet access is an allowlist at every level (network page; open internet access for A1 and A2 is planned), so tests that reach arbitrary sites fail.
Sandbox addresses are under us-dal.coaisandbox.app, the API at api.sandbox.coaiwork.com.
