# How to Install and Use Perplexity in OpenClaw - Tool: OpenClaw - Difficulty: Beginner - Time required: 8 minutes - Last updated: March 2026 ## TL;DR To use Perplexity in OpenClaw, run `clawhub install perplexity`, add your PERPLEXITY_API_KEY to OpenClaw's config, and ask research questions directly in chat. Unlike standard web search skills, Perplexity synthesizes a cited answer from multiple sources rather than returning a raw list of URLs — ideal for research questions that need a reasoned response with verifiable references. ## Why Perplexity Is Different From Every Other Search Skill Every other search skill in ClawHub — Tavily, Brave, Exa, Web Search Plus — returns a list of results. Perplexity does something categorically different: it reads those sources and writes you an answer. When you ask 'What are the current regulations around AI-generated content in the EU?', a standard search skill returns ten links you still have to read. Perplexity reads them for you and returns a structured answer with numbered citations pointing back to the sources it drew from. This synthesis-first approach makes Perplexity the right tool for research questions rather than lookup questions. If you need a specific fact (current EUR/USD exchange rate, the phone number of a business, yesterday's stock price), a fast search skill is more appropriate and cheaper. But if you need to understand a topic, compare options, analyze a situation, or get a briefing on something you do not know well, Perplexity's synthesis format saves significant time. You get a coherent summary rather than a reading list. The citation system is Perplexity's other major advantage for professional use. Every claim in the synthesized answer is tied to a source, which means you can verify information, drill deeper into specific sources, and use the output in contexts that require traceable references — reports, research documents, decision memos. This is what separates Perplexity from simply asking OpenClaw's underlying AI model a question: the answer is grounded in current web sources, not training data that may be months or years out of date. ## Before you start - An OpenClaw account with ClawHub access - A Perplexity account — sign up at perplexity.ai to access API settings - ClawHub CLI installed and working (verify with `clawhub --version`) - Basic understanding of how OpenClaw chat prompts work - A Perplexity API key (free tier available with limited monthly queries) ## Step-by-step guide ### 1. Install the Perplexity ClawHub Skill Run the ClawHub install command to add the Perplexity skill to your OpenClaw installation. ClawHub downloads the skill package and registers it so it becomes available immediately in OpenClaw chat. Open your terminal and run: ``` clawhub install perplexity ``` The install process downloads the skill and its dependencies, which typically takes under 30 seconds. You will see progress output as the skill is fetched from the ClawHub registry. Once the install completes, confirm the skill is active: ``` clawhub list | grep perplexity ``` You should see `perplexity` listed with its version number and an 'active' status. Note: the Perplexity skill is different from search skills like tavily-ai-search or brave-search in how it processes queries. Search skills return lists of results; the Perplexity skill calls Perplexity's sonar models, which read sources and return synthesized prose answers with citations. This means responses take slightly longer than raw search queries (typically 5-15 seconds vs 2-5 seconds) but deliver significantly more actionable information for research questions. ``` # Install the Perplexity skill clawhub install perplexity # Verify installation clawhub list | grep perplexity ``` **Expected result:** The perplexity skill appears in `clawhub list` with a version number and 'active' status. ### 2. Get Your Perplexity API Key The Perplexity skill requires an API key to make requests to Perplexity's sonar models. This key is separate from your Perplexity.ai account credentials — it is specifically for API access. To generate your API key: 1. Log in to your Perplexity account at perplexity.ai. 2. Navigate to Settings (usually via your profile icon in the top right). 3. Look for the 'API' section in the settings sidebar — it may be labeled 'API Keys' or 'Developer'. 4. Click 'Generate API Key'. Give it a name like 'OpenClaw'. 5. Copy the key immediately — it is only shown once. Perplexity offers a free tier for API access with a limited monthly query allowance, which is enough to evaluate the skill and use it regularly for light research. For heavy research workflows (dozens of queries per day), check Perplexity's API pricing at docs.perplexity.ai/docs/pricing. The API key format is typically a long alphanumeric string starting with `pplx-`. Store it securely — it is tied to your Perplexity account and usage billing. Important: this is your API key for the Perplexity API service, not your Perplexity.ai web app login password. The two are separate credentials. The API key is what the OpenClaw skill uses to make programmatic requests to Perplexity's models. **Expected result:** You have a Perplexity API key (starts with `pplx-`) ready to configure in OpenClaw. ### 3. Configure Your PERPLEXITY_API_KEY in OpenClaw Store your Perplexity API key in OpenClaw's config system so the skill can authenticate with Perplexity's API. Never paste API keys directly into chat prompts — store them in config where they are handled securely. **Option 1: OpenClaw config command (recommended)** This writes the key to OpenClaw's encrypted config store: ``` openclaw config set skills.perplexity.apikey YOUR_PERPLEXITY_KEY_HERE ``` **Option 2: .env file in your OpenClaw directory** Open or create `.env` in your OpenClaw data directory: ``` PERPLEXITY_API_KEY=pplx-your-key-here ``` After saving, reload OpenClaw: ``` openclaw reload ``` **Verify the configuration:** ``` openclaw config get skills.perplexity.apikey ``` This should return a masked version of your key (e.g., `pplx-****...****`), confirming it is stored but not exposed in plain text. If you have other Perplexity-connected tools or workflow automations that also need this key, you can set it as an environment variable at the system level — but for OpenClaw specifically, the `openclaw config set` command is the cleanest approach and keeps credentials isolated to OpenClaw's config store. ``` # Store API key via OpenClaw config (recommended) openclaw config set skills.perplexity.apikey pplx-your-key-here # Alternative: .env file approach echo 'PERPLEXITY_API_KEY=pplx-your-key-here' >> ~/.openclaw/.env openclaw reload # Verify the key is stored openclaw config get skills.perplexity.apikey ``` **Expected result:** The config get command returns a masked key value, and OpenClaw confirms the perplexity skill configuration is valid. ### 4. Test the Perplexity Skill with a Research Query With the skill installed and configured, open OpenClaw chat and ask a real research question. The key distinction to understand when writing Perplexity prompts is that you are asking for a synthesized answer, not search results. Frame your prompts as research questions rather than search queries. **Effective prompt patterns for Perplexity:** - 'Research and summarize...' — asks for synthesis - 'What are the current...?' — signals you want up-to-date information - 'Compare X and Y...' — prompts a structured comparison with cited evidence - 'Explain the state of... in 2026' — grounds the answer in current information - 'What do experts say about...?' — requests multi-source perspectives **Less effective for Perplexity (better suited for other skills):** - Simple factual lookups ('What is the population of Tokyo?') — Tavily or Brave are faster and cheaper - URL-specific questions ('What does this specific page say?') — use firecrawl-skills for targeted page extraction - Real-time data ('Current stock price of Apple') — Perplexity is not optimized for live financial data Perplexity's strength is synthesizing and citing. Use it for questions where you need to understand something, not just retrieve a fact. **Expected result:** OpenClaw returns a multi-paragraph synthesized answer with numbered citations linking to the sources Perplexity used, confirming the skill is active and authenticating correctly. ### 5. Advanced Research Patterns: Follow-Up Questions and Focused Queries Perplexity's OpenClaw integration supports multi-turn research sessions where each follow-up question can narrow, expand, or redirect the research. This is one of its most powerful features for deep research workflows. **Multi-turn research sessions:** Ask a broad question first, then follow up with specific angles. OpenClaw maintains context between messages, so Perplexity can refine its previous answer based on your follow-up without you needing to repeat context. **Focused domain queries:** Perplexity performs better when you constrain the scope. Instead of 'Tell me about AI', ask 'What are the specific privacy risks of using AI in healthcare data processing according to EU regulators in 2025-2026?'. Narrower questions produce more accurate, better-cited answers. **Combining Perplexity with other skills:** A powerful workflow is to use Perplexity first for research synthesis (to understand the landscape and identify key sources), then use firecrawl-skills or firecrawl-search to extract full content from specific pages Perplexity cited. This gives you both the synthesized overview and the raw source material. For organizations running systematic research workflows in OpenClaw — competitive intelligence programs, regulatory monitoring, or market research pipelines — the RapidDev team has pre-built prompt templates that combine Perplexity with other ClawHub skills for structured output. Visit rapiddev.ai for examples and customization support. Finally, note that Perplexity's answers are only as current as its web index. For very recent events (last 24-48 hours), results may be less complete than for established topics. ``` # Optional: configure Perplexity to use the pro model for deeper research openclaw config set skills.perplexity.model sonar-pro # View all Perplexity skill configuration options clawhub info perplexity ``` **Expected result:** You are running multi-turn research conversations in OpenClaw with Perplexity providing synthesized, cited answers that you can follow up on or combine with other ClawHub skills. ## Best practices - Frame prompts as research questions rather than search queries — 'Research and summarize the current state of X' produces much better results than 'search for X', because Perplexity is built to synthesize, not just retrieve. - Always ask Perplexity to 'include citations' or 'cite your sources' when you need verifiable output — the citations are the key advantage of Perplexity over standard web search skills. - Add date qualifiers to time-sensitive queries ('as of early 2026', 'in the past 3 months') to signal that recency matters and help Perplexity prioritize fresh sources. - Use Perplexity for understanding and synthesis, not for simple fact lookups — for quick facts, Tavily or Brave Search are faster and cheaper; save Perplexity API credits for complex research questions. - Store your PERPLEXITY_API_KEY via `openclaw config set` rather than in plain text files — the config store encrypts credentials at rest and avoids accidental exposure. - Monitor your Perplexity API usage in the dashboard before running high-volume research workflows — the free tier has monthly query limits that can be exhausted quickly with complex multi-turn research sessions. - Combine Perplexity with firecrawl-skills for deep research: use Perplexity first to identify key sources and get an overview, then use firecrawl-skills to extract full content from specific cited pages. - For multi-turn research sessions, keep the conversation in one OpenClaw chat thread — this maintains context so each follow-up builds on the previous answer rather than starting fresh. ## Use cases ### Competitive Intelligence Research Ask Perplexity to research a competitor, market trend, or technology space and get a synthesized briefing with sources. Instead of spending an hour reading articles, get a structured summary of what is publicly known — pricing, product changes, recent news, customer sentiment — with links to verify each point. Prompt example: ``` Research what analysts and customers are saying about [Competitor Name]'s recent product changes. Summarize key strengths, weaknesses, and any notable pricing or feature shifts reported in the last 6 months. Include citations for each claim. ``` ### Technical Due Diligence on a Topic When evaluating a technology, framework, or approach you are unfamiliar with, Perplexity can synthesize an objective overview from multiple technical sources — documentation, blog posts, benchmark articles, and community discussions. Useful for quickly getting up to speed before a meeting or decision. Prompt example: ``` Explain the current state of WebAssembly for server-side workloads in 2026. What are the main use cases, performance characteristics, known limitations, and which major companies are using it in production? Cite your sources. ``` ### Regulatory and Compliance Briefings Research legal or regulatory requirements in a specific domain and get a synthesized summary rather than reading through dense government documents. Particularly useful for understanding compliance requirements, recent regulatory changes, or jurisdictional differences when entering new markets. Prompt example: ``` What are the current data residency and privacy requirements for storing EU citizen data as of early 2026? Summarize the key obligations under GDPR and any recent enforcement actions or clarifications. Include links to official sources. ``` ## Troubleshooting ### Error: 'Invalid API key' or '401 Unauthorized' on first Perplexity query Cause: The PERPLEXITY_API_KEY is not configured in OpenClaw, was entered incorrectly, or has been revoked in the Perplexity dashboard. Solution: Run `openclaw config get skills.perplexity.apikey` to check if the key is stored. If empty, run `openclaw config set skills.perplexity.apikey YOUR_KEY`. Log into perplexity.ai and verify the API key is still active under Settings → API. If the key was revoked, generate a new one and update the config. ``` # Re-configure the API key openclaw config set skills.perplexity.apikey pplx-your-new-key-here openclaw reload ``` ### `clawhub install perplexity` returns 'package not found' Cause: The local ClawHub registry index is out of date and does not yet have the perplexity skill listed. Solution: Run `clawhub update` to pull the latest registry index, then retry the install. If the problem persists, check that your ClawHub CLI itself is current with `clawhub --version` and update if needed. ``` clawhub update clawhub install perplexity ``` ### Perplexity skill returns 'rate limit exceeded' during queries Cause: Your Perplexity API plan has a monthly query limit that has been reached, or you are hitting per-minute rate limits on the free tier. Solution: Check your usage in the Perplexity API dashboard under your account settings. If you have hit the monthly limit, upgrade your Perplexity API plan. For per-minute rate limits, wait 60 seconds between queries. You can also configure OpenClaw to add automatic query spacing: `openclaw config set skills.perplexity.rate_limit_delay_ms 3000`. ``` # Add delay between Perplexity queries to avoid rate limits openclaw config set skills.perplexity.rate_limit_delay_ms 3000 ``` ### Perplexity answers do not include citations even when requested Cause: The model tier configured for the skill (default: sonar) may return answers with fewer citations for certain query types, or the prompt does not explicitly request citations. Solution: Always include 'cite your sources' or 'include numbered citations' in your prompt. If citations are still sparse, try upgrading to the sonar-pro model: `openclaw config set skills.perplexity.model sonar-pro`. Pro models are better at structured citation outputs. ``` # Switch to sonar-pro for better citation quality openclaw config set skills.perplexity.model sonar-pro ``` ## Frequently asked questions ### How do I install Perplexity in OpenClaw? Run `clawhub install perplexity` in your terminal. After installation, set your API key with `openclaw config set skills.perplexity.apikey YOUR_KEY`. Reload OpenClaw and the skill becomes available in chat immediately. You can verify it is active with `clawhub list | grep perplexity`. ### OpenClaw Perplexity API key configuration — where does it go? Run `openclaw config set skills.perplexity.apikey YOUR_PERPLEXITY_KEY` in your terminal. Alternatively, add `PERPLEXITY_API_KEY=your-key` to the `.env` file in your OpenClaw data directory and run `openclaw reload`. Never paste API keys directly into chat prompts. ### What is the difference between Perplexity and Tavily AI Search in OpenClaw? Perplexity synthesizes a written answer from multiple web sources and provides numbered citations — you get a research briefing, not a list of links. Tavily AI Search returns ranked search results with AI-scored relevance — you get links and snippets to review yourself. Use Perplexity for complex research questions that require understanding; use Tavily for faster discovery and link retrieval. ### ClawHub install perplexity not working — how do I fix it? First run `clawhub update` to refresh the registry, then retry `clawhub install perplexity`. If you get a 429 rate limit error from ClawHub, wait 60 seconds and try again. If the skill name is not found after updating, verify your ClawHub CLI version with `clawhub --version` and update to the latest version if needed. ### Does the Perplexity skill in OpenClaw provide real-time information? Perplexity retrieves information from its live web index, which is regularly updated but not real-time. For very recent events (last 24-48 hours), coverage may be incomplete. For established topics and information from the past several months, Perplexity's synthesis is highly reliable and current. ### How do I get better citation quality from the Perplexity skill? Always explicitly ask for citations in your prompt ('include citations', 'cite your sources', 'provide numbered references'). For consistently better citation outputs, switch to the sonar-pro model: `openclaw config set skills.perplexity.model sonar-pro`. The pro model is more thorough but costs more per query.
