## Description
Developer API gateway providing high-throughput model inference augmented with live web grounding, domain filtering, and structured JSON extraction.

## Access & Pricing
Usage-based per-token pricing; Pro members receive $5/month in free API credits.

## Key Capabilities
- OpenAI SDK-compatible drop-in endpoints (`api.perplexity.ai`).
- Returns grounded answers with inline citation URLs and domain provenance metadata.
- Domain filter flags to restrict inference to vetted internal or technical documentation sites.

## Alternatives & Replaces
- Tavily API ($20-$100/mo)
- Custom web-scraping RAG pipelines

## Robbie's Take
**Robbie's Performance Take:** Ideal for latency-critical agent loops where fast token generation directly reduces user wait times. Benchmark output quality on your specific task before swapping out larger frontier reasoning models.
