Instagram CLI — Agent Usage Guide

Instagram CLI (instagram-cli) is a terminal client for Instagram. For agents, it exposes one-turn commands that print to stdout and exit — perfect for scripting and tool-use.

All one-turn commands require the user to already be logged in (instagram-cli auth login). If a command returns an auth error, prompt the user to log in first. Do not attempt to login using the CLI by yourself.

Thread Resolution

Every command that targets a thread accepts a <thread> argument resolved in this order:

1. Thread ID (20+ digit number like 340282366920938463...) — direct, zero extra API calls
2. Username — exact Instagram username (e.g. johndoe)
3. Thread title — fuzzy search across inbox (e.g. "Book Club")

Best practice for multi-step workflows: call inbox --output json first to get thread IDs, then pass those IDs directly to subsequent commands. This avoids redundant search API calls and is more reliable than username/title matching.

JSON Output

All commands accept -o json / --output json. Responses follow this envelope:

{ "ok": true, "data": { ... } }
{ "ok": false, "error": "message" }

Always use --output json when you need to parse results programmatically.

Commands

List inbox

instagram-cli inbox [--limit <n>] [--output json]

Returns recent threads. Each thread includes: id, title, users, lastMessage, lastActivity, unread.

# Get 10 most recent threads as JSON
instagram-cli inbox --limit 10 --output json

Search threads

instagram-cli inbox --search <query> [--limit <n>] [--output json]

Searches by both username and thread title, merging results by relevance score.

instagram-cli inbox --search "alice" --output json

Send a message

instagram-cli send <thread> --text <message> [--output json]
instagram-cli send <thread> --file <path> [--type photo|video] [--output json]

<thread> is a thread ID, username, or title. --text and --file are mutually exclusive. Media type is auto-detected from extension; use --type to override.

instagram-cli send johndoe --text "Hey, are you free tonight?"
instagram-cli send 340282366920938463123456789 --text "Got it!"
instagram-cli send "Book Club" --file ./photo.jpg --output json

Read messages

instagram-cli read <thread> [--limit <n>] [--cursor <cursor>] [--mark-seen] [--output json]

Returns messages newest-first. Use cursor from the previous response to paginate older messages. Pass --mark-seen to mark the thread as read after fetching.

instagram-cli read johndoe --limit 20 --output json
instagram-cli read 340282366920938463123456789 --mark-seen

Each message in JSON output includes: id, itemType, text, userId, username, timestamp, isOutgoing.

Download media from a message

instagram-cli read <thread> --message-id <id> --download <path> [--output json]

Finds the message by ID (paginates up to --max-pages, default 10) and saves the media file. The file extension is automatically inferred if not provided.

instagram-cli read johndoe --message-id 340282366... --download ./media

Reply to a message

instagram-cli reply <thread> --message-id <id> --text <text> [--output json]

Sends a threaded reply to a specific message.

instagram-cli reply johndoe --message-id 340282366... --text "Totally agree!"

Unsend a message

instagram-cli unsend <thread> --message-id <id> [--output json]

instagram-cli unsend johndoe --message-id 340282366...

Multi-Account Support

All commands accept -u <username> / --username <username> to target a specific logged-in account. Omitting it uses the default account set via instagram-cli auth switch.

instagram-cli inbox -u myworkaccount --output json
instagram-cli send johndoe --text "Hi" -u mypersonalaccount

Typical Agent Workflow

# 1. Get inbox to find the right thread
INBOX=$(instagram-cli inbox --output json --limit 20)
# Parse "id" fields from INBOX to find the target thread

# 2. Read recent messages (use thread ID for speed)
THREAD_ID="340282366920938463..."
instagram-cli read "$THREAD_ID" --limit 10 --output json

# 3. Reply or send
instagram-cli send "$THREAD_ID" --text "On my way!" --output json

# 4. Mark as seen
instagram-cli read "$THREAD_ID" --mark-seen

Error Handling

• Auth errors → user needs to run instagram-cli auth login
• "No thread found matching" → the username/title didn't resolve; try inbox --search first
• "ok": false in JSON output → the error field contains the reason
• Rate limits / network errors are surfaced as error messages; retry with backoff if needed
