Sonar Inference API & Agent Gateway

Grounded API Gateway

Overview & Capability

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

Key Highlights

  • 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.
Robbie's Independent Take Verified: 2026-10-11

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.

Alternatives & Replaces

  • Tavily API ($20-$100/mo)
  • Custom web-scraping RAG pipelines
