Perplexity (Web Search Provider)

The Perplexity plugin provides web search capabilities through the Perplexity Search API or Perplexity Sonar via OpenRouter.

This page covers the Perplexity **provider** setup. For the Perplexity **tool** (how the agent uses it), see [Perplexity tool](/tools/perplexity-search).

Property	Value
Type	Web search provider (not a model provider)
Auth	PERPLEXITY_API_KEY (direct) or OPENROUTER_API_KEY (via OpenRouter)
Config path	plugins.entries.perplexity.config.webSearch.apiKey

Getting started

Run the interactive web-search configuration flow:

```bash
openclaw configure --section web
```

Or set the key directly:

```bash
openclaw config set plugins.entries.perplexity.config.webSearch.apiKey "pplx-xxxxxxxxxxxx"
```

The agent will automatically use Perplexity for web searches once the key is configured. No additional steps are required.

Search modes

The plugin auto-selects the transport based on API key prefix:

When your key starts with `pplx-`, OpenClaw uses the native Perplexity Search API. This transport returns structured results and supports domain, language, and date filters (see filtering options below). When your key starts with `sk-or-`, OpenClaw routes through OpenRouter using the Perplexity Sonar model. This transport returns AI-synthesized answers with citations.

Key prefix	Transport	Features
pplx-	Native Perplexity Search API	Structured results, domain/language/date filters
sk-or-	OpenRouter (Sonar)	AI-synthesized answers with citations

Native API filtering

Filtering options are only available when using the native Perplexity API (`pplx-` key). OpenRouter/Sonar searches do not support these parameters.

When using the native Perplexity API, searches support the following filters:

Filter	Description	Example
Country	2-letter country code	us, de, jp
Language	ISO 639-1 language code	en, fr, zh
Date range	Recency window	day, week, month, year
Domain filters	Allowlist or denylist (max 20 domains)	example.com
Content budget	Token limits per response / per page	max_tokens, max_tokens_per_page

Advanced notes

If the OpenClaw Gateway runs as a daemon (launchd/systemd), make sure `PERPLEXITY_API_KEY` is available to that process.

<Warning>
A key set only in `~/.profile` will not be visible to a launchd/systemd
daemon unless that environment is explicitly imported. Set the key in
`~/.openclaw/.env` or via `env.shellEnv` to ensure the gateway process can
read it.
</Warning>

If you prefer to route Perplexity searches through OpenRouter, set an `OPENROUTER_API_KEY` (prefix `sk-or-`) instead of a native Perplexity key. OpenClaw will detect the prefix and switch to the Sonar transport automatically.

<Tip>
The OpenRouter transport is useful if you already have an OpenRouter account
and want consolidated billing across multiple providers.
