Vibe Coding Alert

Full transparency: this project was built by a non-developer using AI coding assistants. If you're an experienced Python developer, you might look at this codebase and wince. That's okay.

The goal here was to learn — both about building CLI tools in Python and about how modern web applications work under the hood. The code works, but it's very much a learning project released solely for the purpose of research and education, not a polished product.

[!WARNING] Unofficial & Unsupported — This project is not affiliated with, endorsed by, or supported by Perplexity AI. It interacts with Perplexity's web interface through unofficial, undocumented methods that may break at any time without notice if Perplexity changes their internal APIs or RPCs. Use at your own risk. The author(s) accept no responsibility for any consequences to your Perplexity account, including but not limited to rate limiting, suspension, or termination. This project is released strictly for educational and research purposes only.

If you know better, teach us. PRs, issues, and architectural advice are all welcome. This is open source specifically because human expertise is irreplaceable.

CLI Reference

Querying

Ask Perplexity a question. By default, Perplexity auto-selects the best model.

pwm ask "What is quantum computing?"

Choose a specific model with -m (see Models for the full list):

pwm ask "Compare React and Vue" -m gpt54

pwm ask "Explain the attention mechanism" -m claude_sonnet

Enable extended thinking with -t for deeper reasoning (available on models with Toggle thinking):

pwm ask "Prove that the square root of 2 is irrational" -m claude_sonnet --thinking

Focus on specific sources with -s to control where Perplexity searches:

# Search only academic papers and scholarly articles
pwm ask "transformer architecture improvements 2025" -s academic

# Search only social media (Reddit, Twitter, etc.)
pwm ask "best mechanical keyboard 2026" -s social

# Search SEC EDGAR financial filings
pwm ask "Apple revenue Q4 2025" -s finance

# Search all source types at once
pwm ask "latest AI news" -s all

Output options:

# JSON output (for piping to other tools)
pwm ask "What is Rust?" --json

# Suppress citation URLs (answer text only)
pwm ask "What is Rust?" --no-citations

Combine flags for full control:

pwm ask "recent advances in protein folding" -m gemini_pro -s academic --json

Deep Research

Run Perplexity's Deep Research mode for in-depth reports with extensive sources. Uses a separate monthly quota.

pwm research "agentic AI trends 2026"

pwm research "climate policy impact on renewable energy" -s academic

pwm research "NVIDIA competitive landscape" -s finance --json

Model Council

Query multiple models in parallel and get a synthesized consensus. Each model costs 1 Pro Search. Default synthesis uses Sonar 2 (also 1 Pro Search).

# Default: GPT-5.4, Claude Opus, Gemini Pro + Sonar 2 synthesis (4 Pro Searches)
pwm council "What are best practices for microservices?"

# Custom model selection
pwm council "Compare Rust and Go" -m gpt54,claude_sonnet

# Enable extended thinking for all council models
pwm council "Prove the Pythagorean theorem" --thinking

# Skip synthesis, output as JSON
pwm council "React vs Vue" --no-synthesis --json

Authentication

pwm login                                    # Interactive login (email + OTP)
pwm login --check                            # Check if authenticated
pwm login --email user@example.com           # Send verification code (non-interactive)
pwm login --email user@example.com --code 123456  # Complete auth with code

Usage & Limits

pwm usage                  # Check remaining rate limits
pwm usage --refresh        # Force-refresh from Perplexity servers

Hack

Seamlessly launch external AI tools connected to the Perplexity API server. This automatically starts the local pwm api server in the background, sets the required environment variables, and launches the tool.

pwm hack claude            # Launch Claude Code
pwm hack claude -m gpt54   # Launch Claude Code with a specific model

API Server

Use Perplexity models through Anthropic or OpenAI compatible API endpoints.

Start the server

pwm api

Anthropic API (Claude Code)

export ANTHROPIC_BASE_URL=http://localhost:8080
export ANTHROPIC_API_KEY=perplexity
claude --model gpt-5.4

Alternatively, launch Claude Code seamlessly using the hack command, which automatically starts the API server and configures the environment for you:

pwm hack claude

OpenAI API

export OPENAI_BASE_URL=http://localhost:8080/v1
export OPENAI_API_KEY=anything

API Model Names

| API Name | Perplexity Model | Thinking | |----------|------------------|----------| | perplexity-auto | Best (auto-select) | No | | gpt-5.4 | GPT-5.4 | Toggle | | claude-sonnet-4-6 | Claude 4.6 Sonnet | Toggle | | claude-opus-4-7 | Claude 4.7 Opus | Toggle | | gemini-3.1-pro | Gemini 3.1 Pro | Always | | nemotron-3-super / nemotron | Nemotron 3 Super | Always |

Legacy aliases (claude-3-5-sonnet, claude-3-opus) are supported for compatibility.

---

Python API

from perplexity_web_mcp import Perplexity, ConversationConfig, Models

client = Perplexity(session_token="your_token")
conversation = client.create_conversation(
    ConversationConfig(model=Models.CLAUDE_45_SONNET)
)

conversation.ask("What is quantum computing?")
print(conversation.answer)

for result in conversation.search_results:
    print(f"Source: {result.url}")

# Follow-up (context preserved)
conversation.ask("Explain it simpler")
print(conversation.answer)

---

Subscription Tiers & Rate Limits

| Tier | Cost | Pro Search | Deep Research | Labs | |------|------|------------|---------------|------| | Free | $0 | 3/day | 1/month | No | | Pro | $20/mo | Weekly pool | Monthly pool | Monthly pool | | Max | $200/mo | Weekly pool | Monthly pool | Monthly pool |

The MCP server checks quotas before each query. Use pwm usage or pplx_usage to check your limits.

---

Troubleshooting

Authentication Errors (403)

Session tokens last ~30 days. Re-authenticate when expired:

pwm login

Non-interactive (for AI agents):

pwm login --email your@email.com

pwm login --email your@email.com --code 123456

Via MCP tools (for AI agents without shell):

1. Call pplx_auth_request_code(email="your@email.com")
2. Check email for 6-digit code
3. Call pplx_auth_complete(email="your@email.com", code="123456")

Diagnose Issues

pwm doctor

This checks installation, authentication, rate limits, MCP configuration, and skill installation -- with fix suggestions for every issue found.

Rate Limiting

• CLI/MCP: Auto-checks quotas before each query, blocks if exhausted
• API server: Enforces 5-second minimum between requests

---

Agent Skill

This project includes a portable Agent Skill (SKILL.md) that teaches AI agents how to use the CLI and MCP tools. Install it for your platform:

pwm skill install all              # Install for all detected tools
pwm skill install claude-code      # Or install individually
pwm skill install cursor
pwm skill install codex
pwm skill install gemini-cli
pwm skill install antigravity
pwm skill install cline
pwm skill install opencode
pwm skill install openclaw
pwm skill install alef-agent

The skill follows Anthropic's Agent Skills open standard and works across any compliant AI platform.
