Secure temporary file sharing for AI agents and humans.
A scriptable CLI with expiring links, predictable JSON, and optional local age encryption.

Website · Documentation

aispace.sh is a bot-friendly file drop for outputs that are too large, structured, or temporary for chat. The open-source client is deliberately easy to automate: one binary, stable exit codes, streaming uploads, and share URLs printed on a predictable final line.

• Built for agents: exact JSON output, documented errors, stdin support, and no interactive prompts in automated flows.
• Short-lived by design: file expiration, separately expiring links, revocation, and optional per-link download caps.
• Private when needed: authenticated account handoffs and local age X25519 encryption; the decryption identity never reaches aispace.

The hosted service is operated separately. This repository contains the client, agent skill, and integration examples—not the server, billing system, deployment configuration, or customer data.

Install the latest release:

curl -fsSL https://aispace.sh/install.sh | sh

Authenticate with a key created in the aispace dashboard, then store a file:

aispace login --key ask_...
aispace upload report.pdf --json

On a Pro account, add a separately expiring public handoff:

aispace upload report.pdf --link --link-expires 1h --max-downloads 1

The URL is printed last on its own line, making it easy for an agent or shell script to capture. Add --json for a stable machine-readable response. An abridged response looks like:

{"file":{"id":"...","name":"report.pdf"},"link":{"url":"https://aispace.sh/d/...","expires_at":1757003600}}

Other installation channels:

npm install -g @aispace-sh/cli
brew install aispace-sh/tap/aispace
go install github.com/aispace-sh/aispace-client@latest

Pin the shell installer with AISPACE_VERSION=v1.2.3. Release binaries support macOS, Linux, and Windows on amd64 and arm64. The shell installer supports macOS and Linux; use npm on Windows.

The repository includes a reusable Codex-compatible skill. Clone the repository and link the skill into your personal Codex skills directory:

git clone https://github.com/aispace-sh/aispace-client.git
mkdir -p ~/.codex/skills
ln -s "$PWD/aispace-client/skills/aispace" ~/.codex/skills/aispace

Restart Codex, then ask it to use aispace when it needs to hand you a report, archive, image, or other generated artifact. The skill defaults to account-private storage unless you request a public link, prefers short expirations, and treats encryption identities as credentials.

For custom agent runtimes, docs/LLM_USAGE.md includes a system-prompt snippet, OpenAI/Anthropic-compatible tool schemas, and a reference Python handler. See examples for runnable shell, CI, and encrypted-handoff recipes.

# Upload text from stdin and return an expiring public link (Pro).
echo "hello" | aispace upload - --name note.txt --link --link-expires 1h

# Keep a file available only to this key.
aispace upload secret.txt --private

# Share ciphertext; keep the generated age identity locally.
aispace upload secret.pdf --encrypt --identity-out secret.agekey --link

# Authenticated handoff to another key on the same account—no public URL.
aispace upload notes.md --shared --json

# Receive, manage, and revoke.
aispace ls --json
aispace download <file_id> --output ./file
aispace download <file_id> --output ./file --verify   # check the recorded SHA-256
aispace link <file_id> --expires 30m --max-downloads 1
aispace revoke <link_id>
aispace rm <file_id>

The complete command reference is in docs/CLI.md; the HTTP contract is in docs/API.md.

upload accepts --name, --expires, --content-type, --sha256, --link, --link-expires, --max-downloads, --private, --shared, --encrypt, --recipient, and --identity-out. Uploads stream from disk. Encrypted uploads use age X25519 locally and store ciphertext as <name>.age; the secret identity is never sent to the API.

With --json, errors also remain structured and are written to stderr. upload --link --json returns {"file": File, "link": ShareLink}; encrypted uploads add an "encryption" object.

Precedence: flag > environment > config file > default.

AISPACE_AGE_IDENTITY supplies a decryption identity when decrypt --identity-file is omitted. It is deliberately not accepted as a command-line value.

Config file: $XDG_CONFIG_HOME/aispace/config.json (default ~/.config/aispace/config.json), written with mode 0600. A warning is printed if the file is readable by others. AISPACE_CONFIG overrides the path.

Durations (--expires, --link-expires) accept Go syntax plus a d suffix: 30m, 24h, 7d, 1d12h, or a bare number of seconds. Omitting them uses the server defaults (7 days for files, 1 hour for links).

File visibility controls authenticated key access. A public link is a separate capability: creating one requires a Pro account and makes that one file available to anyone holding the URL.

Available duration syntax includes 30s, 15m, 1h, 36h, and 7d.

A file becomes unavailable when its file lifetime ends. A link can end sooner because it expired, was revoked, or reached its download cap. Deleting the file immediately ends authenticated key access and every associated public link.

Errors go to stderr as error: <message> (<code>); with --json they are a JSON object {"error":{"code","message","status","details","exit_code"}} on stderr instead.

go test -race ./... && go vet ./... && test -z "$(gofmt -l .)"
go build -ldflags "-X main.version=0.0.0-dev" -o aispace .
(cd npm && npm test && npm pack --dry-run)

The test suite uses local HTTP fixtures and does not require an aispace key. Contributions are welcome—start with CONTRIBUTING.md, check the ROADMAP.md, and review the CHANGELOG.md. Focused bug reports and feature proposals can use the repository's structured issue forms.

Releases are cut through the manual GitHub Actions workflow. GoReleaser builds checksummed macOS, Linux, and Windows binaries, updates the Homebrew tap, and publishes @aispace-sh/cli to npm. See RELEASE.md for publisher configuration and the release checklist.

Please report vulnerabilities privately through GitHub Security Advisories. Do not open a public issue containing a credential, private link, or customer data. See docs/SECURITY.md.
