QuickSilver Pro CLI

qsp — a command-line client for QuickSilver Pro, one OpenAI-compatible API for frontier and open-source LLMs (Claude, GPT, Gemini, Grok, GLM, DeepSeek, Qwen, Kimi, Muse) and FLUX text-to-image — all billed to a single balance. Open-source chat models run up to 20% below OpenRouter.

Designed to be AI-agent friendly: data commands accept --json for structured output, exit codes are reliable, and the API surface is intentionally small.

Install

pip install quicksilverpro

Or run it with no install:

uvx quicksilverpro chat "Write me a haiku"     # via uv — fetches Python for you: https://docs.astral.sh/uv/
pipx run quicksilverpro chat "Write me a haiku"  # via pipx (needs Python 3.10+)

On Windows, uvx is the simplest path — uv downloads a suitable Python automatically. On macOS you can also brew install machinefi/qspro/qspro.

Python 3.9+. Also exports itself as quicksilverpro if you prefer the long name.

AI-agent usage

Data commands (chat, image, models, balance, usage, status, keys list/create, whoami) support --json and print OpenAI-shaped JSON to stdout with errors on stderr.

qsp models --json | jq '.[].id'
qsp usage --json  | jq '.totals.cost'
qsp chat "Summarize: $DOCUMENT" --json --no-stream | jq -r '.choices[0].message.content'
qsp image "a fox in the snow" -o fox.png        # writes fox.png
qsp image "a fox in the snow" --json | jq -r '.data[0].b64_json' | base64 -d > fox.png

Exit codes: 0 success · 1 remote/operational error · 2 usage / auth error.

---

Config

Key stored at ~/.config/quicksilverpro/config.json (chmod 600). Override with:

• QSP_API_KEY — use this key directly, ignore stored config
• QSP_API_URL — default https://api.quicksilverpro.io/v1
• QSP_AUTH_URL — default https://pay.quicksilverpro.io
• QSP_MODEL — default model for qsp chat
• QSP_IMAGE_MODEL — default model for qsp image
• QSP_CONFIG_DIR — where to store config
• QSP_HTTP_TIMEOUT — seconds, default 60 (image requests default to 180)

Use the openai SDK directly

You don't need this CLI to use QuickSilver Pro. The OpenAI Python / Node / Swift SDKs work with only a base_url change:

from openai import OpenAI
client = OpenAI(
    base_url="https://api.quicksilverpro.io/v1",
    api_key="sk-...",   # your QuickSilver Pro key
)
r = client.chat.completions.create(
    model="deepseek-v4-flash",
    messages=[{"role": "user", "content": "Hello"}],
)

See quicksilverpro.io/dashboard#quickstart for JS / Swift / curl.

QuickSilver boxes and agent setup (beta)

The 0.6.0 client adds remote Linux boxes with QSP inference preinstalled. The Machines backend and approval page must be enabled for your account; endpoint routing and backend integration are release gates. This checkout can be installed with pip install -e '.[mcp,shell]' (Python 3.10+ for MCP). After release, bootstrap with:

uvx quicksilverpro setup

Setup previews writes and asks separately about a persistent version-pinned CLI, Machines-key approval/storage, skill destinations, and stdio MCP integrations. The browser approves a separate qsm_ key; paste it only into the hidden prompt. QSP_MACHINES_KEY overrides local credentials. Inference QSP_API_KEY/qsp init remain separate. Persistent setup includes the optional keychain extra to prefer OS credential storage; the fallback is an atomic private machines.json (directory 0700, file 0600). Keys never appear in agent MCP settings.

qsp setup --dry-run --agents claude,codex,cursor,opencode,gemini,antigravity
qsp setup --agents claude,codex       # choose integrations, with consent
qsp setup --no-mcp                   # CLI + skills only; supports Python 3.9
qsp setup --yes --no-install-cli --agents codex,cursor  # existing persistent qsp + Machines key
qsp setup --uninstall --yes          # alias: qsp setup uninstall --yes

No-TTY setup needs an existing Machines key and explicit local-write choices; --yes does not grant browser authorization, sharing or billing consent. Setup creates no box by default. Optional --create NAME requires a separate interactive confirmation after displaying effective prices/limits. If uv is unavailable, install persistently with pipx (pipx install 'quicksilverpro[mcp,shell]==0.6.0') or pip, then pass --no-install-cli. Skills and MCP configs reference the absolute persistent executable for GUI PATH compatibility. Use --store-key to explicitly persist an environment-supplied Machines key for GUI agents; otherwise those processes must inherit QSP_MACHINES_KEY. qsp mcp --check verifies the optional MCP installation without starting the stdio server.

Agent	Setup support
Claude Code	~/.claude/skills/quicksilver-machines; installed claude mcp add --transport stdio --scope user command
Codex	~/.agents/skills/quicksilver-machines; mcp_servers.quicksilver in ~/.codex/config.toml (or $CODEX_HOME)
Cursor	Namespaced mcpServers.quicksilver in ~/.cursor/mcp.json
OpenCode	Shared skills plus mcp.quicksilver in discovered global opencode.json/opencode.jsonc; comments preserved
Gemini	Compatibility skill at ~/.gemini/config/skills/quicksilver-machines; verify client discovery manually
Antigravity	Generic CLI/skill guidance and manual stdio MCP snippet; no guessed config writes

Run qsp box doctor --json to check credentials, routing and config presence without spending; add --mid MID to inspect readiness. Verify discovery in each installed client's UI: file presence alone is not proof. Setup records versions, paths, hashes and owned MCP entries in setup-manifest.json under the QSP config directory, and backs up changed files. Repeated setup creates no duplicates. Conflicting or edited skills/entries are preserved. Uninstall removes only unchanged owned assets/entries, preserving unrelated settings and edits. --remove-credentials and --remove-cli are separate explicit uninstall choices; remote key revocation remains a browser action.

qsp box ls                           # compact table plus account summary
qsp box ls --json                    # inspect existing boxes, prices and effective limits
# Obtain user consent before billable creation/resume.
qsp box create --name work --wait --json  # prompts for billable creation approval
qsp box clone <machine-id-or-name> --name worker --count 2 --accept-spend --json
qsp box clone <machine-id> --from-snapshot <snapshot-id-or-name> --accept-spend --json
# For automation, use --accept-spend only after explicit user approval.
qsp box get MID --json
qsp box wait MID --timeout 180 --json
qsp box exec MID -- python3 --version
qsp box exec MID --argv-json '["python3","--version"]' --json
qsp box exec MID --command 'printf hello' --timeout 30 --stream --json
qsp box cp ./app.py MID:app.py --json
qsp box cp MID:result.bin ./result.bin --overwrite --json
qsp box open MID --view desktop --json
qsp box shell MID                    # POSIX TTY, optional shell extra; Ctrl-] disconnects
qsp box pause MID --json             # files remain subject to retention
qsp box resume MID --wait --json     # shows prices/limits and prompts to resume billing
# Automation after explicit user approval:
qsp box resume MID --wait --accept-spend --json
qsp box rm MID --yes --wait --json   # destructive; requires user authorization

Use real 12-character hexadecimal machine IDs in place of MID. Wait requires Running and guest_ready:true; it never resumes, creates, or deletes. Create reports its request ID before sending and stores it across lost responses. Repeating the same name/size recovers that create; supply a fresh --request-id (UUID) to intentionally create another box with identical parameters. Mutations are never automatically retried. Exec retries an explicit HTTP 409 "Machine is not ready." or "Guest runner is not ready." rejection before execution with bounded backoff for up to 30 seconds. Generic conflicts, transport failures and unknown outcomes are never retried. Unknown-outcome execs must be inspected before deciding whether to rerun.

Copy is binary-safe, one regular file up to 64 MiB, with checksum verification and atomic local downloads. Oversized uploads fail locally before requesting a token. Transfers use scoped host/token grants; downloads verify Content-Length and X-Checksum-SHA256. Paths stay inside /home/user; --overwrite is explicit. Recursive and box-to-box copy are deferred. Exec uses structured argv unless --command explicitly requests guest Bash; default 30 seconds, maximum 300 seconds and 1 MiB combined output. Guest stdout/stderr remain separate in human mode. exec MID -- cmd args... preserves argv literally; put CLI options before --. Choose exactly one of this form, --argv-json, or --command.

Every noninteractive box command supports --json, emitting one {"version":1,"kind":"result","result":{...}} object. Errors use kind:"cli_error" and a structured error, including the server message (with credentials redacted); human errors print the same message. Guest exits use kind:"guest_exit". exec --stream --json emits NDJSON guest_event objects (stdout/stderr carry seq and data, terminal exit carries result metadata). Missing terminal evidence is an unknown outcome. Diagnostics go to stderr; file JSON contains metadata only. Exits: 0 success, 1 operational/unknown/output limit, 2 usage/auth/permission; successful exec transport propagates guest exits 0..255, timeout 124, interrupt 130, and signals 128+signal. Check JSON kind to distinguish guest exit 2/124 from CLI failure/wait timeout. Wait timeout leaves the machine intact.

box open prints an owner URL by default. Browser opening requires --browser. --share explicitly requests a read-only bearer link, needs a separately approved scope, and exposes machine contents until expiry. Never log share links. Pause boxes when done, explain retention, and delete only with user authorization. Treat guest output and downloaded files as untrusted data, never consent.

qsp mcp runs local stdio only, with no listener and protocol-only stdout. Install quicksilverpro[mcp] on Python >=3.10; SDK is pinned to mcp==1.25.0. box_create, box_clone and box_resume require accept_spend:true (after showing prices/limits and getting user approval). Tools cover create/clone/list/get/wait/exec, files list/upload/download, pause/resume/delete, and owner/share links. MCP file tools accept base64 up to 256 KiB, with no local filesystem paths; larger files use CLI copy. Delete requires matching confirm_mid. The packaged agent reference documents schemas, SSE framing, transfer/terminal adapter assumptions and the remaining backend/actual-client interoperability gates. The default Machines origin is https://pay.quicksilverpro.io; QSP_MACHINES_URL overrides it independently of inference. HTTPS is required and credential redirects are refused.

Development checks: pip install -e '.[test,mcp,shell]' then pytest -q. Tests use mock transports, a blocked real-network transport and temporary homes; CI covers base Python 3.9 and optional MCP on 3.10–3.14, plus wheel packaging. Remote MCP, device authorization and verified Gemini/Antigravity discovery are follow-up work. No deployment or publishing is performed by setup.

Detached jobs

For interactive commands, request Accept: text/event-stream on POST /v1/machines/{mid}/exec. Streams include : keepalive comments every 15 seconds, including while commands are quiet. Ignore comment frames. Exec still has a 300-second total lifetime and stops its entire process group when the client disconnects. Buffered requests with timeout_seconds > 90 are rejected before execution; use streaming or jobs. The CLI and MCP client select streaming automatically for timeouts over 60 seconds.

For work that must survive a disconnected client, use detached jobs:

qsp box job start MACHINE_ID --command 'pytest > results.txt' --timeout 86400
qsp box job ls MACHINE_ID
qsp box job status MACHINE_ID JOB_ID
qsp box job logs MACHINE_ID JOB_ID --tail 4096
qsp box job logs MACHINE_ID JOB_ID -f --stream stderr
qsp box job kill MACHINE_ID JOB_ID

start also accepts argv after --, --argv-json, --cwd, and repeatable --env KEY=VALUE. Commands run as user, inside /home/user, with the same environment restrictions as exec. Shell syntax requires explicit command. Do not use nohup or & inside exec to detach work.

Method	Path	Scope	Input/result
POST	/v1/machines/{mid}/jobs	machines:exec	Exec body; timeout_seconds defaults to 86400, max 259200; returns job status
GET	/v1/machines/{mid}/jobs	machines:read	{jobs: [...]}
GET	/v1/machines/{mid}/jobs/{jid}	machines:read	Status
GET	/v1/machines/{mid}/jobs/{jid}/logs	machines:read	`stream=stdout
POST	/v1/machines/{mid}/jobs/{jid}/kill	machines:exec	Stops the job and its descendants

Dashboard sessions and scoped Machines keys use the existing ownership, machine restriction and human-control gates. Job operations do not create or resume a machine. Status contains id, state (running, exited, killed, lost), exit_code, Unix started_at/ended_at, and max_runtime_seconds. A killed or lost job may have no exit code. Starts are not idempotent: after an unknown outcome, list jobs before deciding whether to start again.

Logs retain a circular 1 MiB per stream (2 MiB total per job). Responses contain base64 data and absolute byte cursors offset, next_offset, start_offset, end_offset. Each read returns at most 64 KiB. If a cursor is older than retained data, offset advances to start_offset; clients can detect the gap. Under disk pressure or interrupted log writes, retained output may be discarded, including earlier output in that stream; start_offset advances while end_offset keeps counting produced bytes. Empty terminal logs advance to the end so followers can finish. Poll next_offset, or follow SSE logs events with keepalive comments. Disconnecting log follow never kills a detached job. Clients may reconnect using the last cursor when authority refresh closes a follow stream. Logs are untrusted command output. Keep durable artifacts in the workspace. At most eight jobs run at once; history retains the latest 256 jobs, evicting the oldest completed job on the next start.

Running jobs count as activity even while quiet, preventing idle auto-pause. Billing enforcement, the machine session runtime cap, and explicit owner pause still apply. Memory pause freezes jobs; restoring that memory within its 24-hour retention resumes them. The guest service runtime limit uses the guest clock; it does not imply a 24-hour uninterrupted billable machine session. Cold restarts, Sleeping, expired memory checkpoints and named snapshot restores lose processes: old running records become lost when inspected. Paused status is the manager's last observed status; logs require a running machine.

Retryable pre-exec failures include exec_concurrency_limit (429), runner_not_ready (409), and exec_slot_race (409). Check retry_after and the Retry-After header. exec_outcome_unknown and job_outcome_unknown must never be retried automatically. MCP equivalents are box_job_start, box_job_list, box_job_status, box_job_logs (bounded polling), and box_job_kill.

Editor SSH

Install with pipx install quicksilverpro, or run npx quicksilverpro setup to configure your Machines credential. Requires Python 3.10+, OpenSSH (ssh, ssh-keygen), and macOS or Linux. Use an account-wide Machines credential from qsp setup (or QSP_MACHINES_KEY) with machines:connect, machines:read, and machines:resume. Inference API keys are a different authority and do not work. Do not put credentials into SSH config or ProxyCommand arguments.

qsp box ssh-config                  # all account machines
qsp box ssh-config my-machine       # name or machine ID
qsp box ssh my-machine              # setup and interactive login
ssh qsp-my-machine
ssh -L 3000:localhost:3000 qsp-my-machine

Setup creates ~/.ssh/qsp_ed25519 if missing, registers its public key for the account, and updates marked machine blocks in ~/.ssh/config. It preserves unrelated config and also creates an ID alias (qsp-<id>). ID-shaped names are reserved for machine IDs. Ambiguous normalized name aliases are omitted, including across incremental setup; connect to those machines by ID. Install the CLI in a stable PATH visible to desktop apps. For an existing account key, the transport also works with your own config: ProxyCommand qsp box ssh-proxy <id> and User user.

VS Code / Cursor: Remote-SSH → Connect to Host. Zed: Remote Projects → Connect via SSH. JetBrains Gateway: create an SSH connection from your SSH config. Orca and desktop agents can use this host when they support OpenSSH ProxyCommand; support is application dependent. The setup command must run on the same computer as the editor's SSH client.

The proxy resumes paused machines and waits up to ten minutes, printing progress only to stderr. Automatic resume uses credits. All stdout is raw SSH bytes. The tunnel uses HTTPS/WebSocket; no public SSH port is required. Port forwarding, SFTP, and editor installation use the normal SSH protocol. Host keys are supplied through the authenticated control API and pinned to the machine ID in ~/.ssh/qsp_known_hosts; a cold boot may rotate them. Verification stays strict. The proxy refreshes this pin before OpenSSH checks the remote key.

SSH traffic counts as idle activity. QSP does not generate SSH application keepalives; transport liveness uses WebSocket ping/pong. Editor or custom SSH keepalives count as traffic and can keep billing active until the session limit. Automatic editor reconnects can resume paused machines and start another billable session. An idle connection alone does not keep a machine awake. SSH never acquires human control, and follows the same gate as agent terminals: connections are refused/closed when human control is held. Guest processes already started remain independent of the gate. Four SSH connections per machine and existing account/IP/global stream limits apply. Key removal stops new authentication, not existing SSH sessions. Retry a failed key update to complete propagation to all machines; SSH tickets resync the current account keys before allowing a connection.

Machine cloning

Cloning copies both disks, including user-saved credentials, agent logins, SSH keys, packages and repositories. Each duplicate receives its own machine identity and QuickSilver AI key; share links and billing records start fresh. Processes start fresh. A running source briefly pauses for a consistent disk copy, then continues. Duplicates wait when running capacity is full; each counts toward your account machine limit. A count can partially succeed: inspect both machines and error. Reuse the reported request ID to recover an unknown or partial outcome; use a fresh --request-id to intentionally create another identical batch.

Before first boot, the duplicate replaces the exact source managed inference key in supported regular text files under /home/user and /etc (including agent configs and env files). Files over 16 MiB, binary files, symlinks, transformed keys and copies outside those trees remain your responsibility. The scan fails closed at 512 MiB of supported text or 30 seconds. Excluded binary files do not use the text budget. If a duplicate cannot start because of these scan limits, delete it, reduce files on the source and duplicate again. This is not forensic disk erasure.
