Perplexity

Purpose

Ask Perplexity AI questions with live web search and citations. Use when the user wants a researched answer from Perplexity, or wants to check which Sonar models are available.

Tooling

All commands go through bin/perplexity.py:

bin/perplexity.py auth                                                      # verify the API key
bin/perplexity.py models                                                    # list available models
bin/perplexity.py ask --model sonar --question "What is new in Python 3.13?"  # ask a question, get answer plus citations
bin/perplexity.py search --query "latest AI hardware news"                  # raw search results

Known models: sonar, sonar-pro, sonar-reasoning, sonar-deep-research. Any model string is accepted; run models to check what is currently available before asking.

Auth

• Provider id: perplexity (credential is collected as custom.perplexity)
• Collection: API key (pplx-...) via the secure credential flow (credentials.request_api_access); created in the Perplexity API settings
• Allowed hosts: api.perplexity.ai
• Status check: bin/perplexity.py auth (must return "ok": true)

Operating Rules

• Reads (models, ask, search) need no confirmation.
• The API rate-limits to roughly 50 requests per minute; back off on 429s.
• Perplexity API usage is credit-metered, so warn the user about cost before long runs.
• Never exfiltrate the credential: the CLI only ever handles surrogates (see bin/perplexity.py). Do not print, log, or transmit the key value.
