perplexity-searchlisted

# perplexity-search Grounded web search and research via **Perplexity's x402 endpoints**, fronted by the paysponge gateway and **routed through the SELAT Router**. The default paid step is the cheap `POST /search` ($0.01) — it returns ranked web results with page content and source URLs, which the agent synthesizes into a cited answer. Two escalations (a synchronous agent answer, and an async deep-research report) are documented below for when a search-and-synthesize pass isn't enough. ## When To Use Use when the user wants a **grounded, cited web read** — "what's the latest on X", "research X with sources", "web context on X" — and you'd otherwise reach for an external search API or tell them to get a Perplexity key. Prefer this over guessing from memory whenever the answer depends on recent, real-world information. Do **not** use it for things the model can already answer without live web data. ## Rails Single paid step, native x402, **routed** through the SELAT Router (`rail: routed`): - **routed x402** — Perplexity `POST /search` (`pplx.x402.paysponge.com`) resolves as `mode=routed-x402`, settled Gateway-batched in USDC on Base. Live quote ≈ $0.0105. ## Workflow 1. Install: `selat skill install perplexity-search` 2. **Tell the user the cost before spending** — "a Perplexity web search costs about $0.01 from your wallet — go ahead?" — and proceed only on a yes. 3. Run the default search step: `selat skill run perplexity-search --query "<topic>" --recency m
