Perplexity
Agent API, Router API, Search API, Embeddings API — Sonar deprecated Sept 27, 2026
Perplexity has restructured its API platform in 2026. Sonar Chat Completions is now the Agent API, which provides access to third-party models (OpenAI, Anthropic, Google, xAI, Z.AI, Moonshot AI, NVIDIA) at direct provider rates with no markup. The Router API routes requests across models with per-token billing. The Search API provides real-time web retrieval billed per request. The Embeddings API offers pplx-embed-v1 models. Sonar is deprecated September 27, 2026. Check docs.perplexity.ai/docs/getting-started/pricing for current rates.

Perplexity FAQs
What APIs does Perplexity offer in 2026?
Perplexity offers four APIs: Agent API (multi-step agentic tasks with third-party models at direct provider rates), Router API (intelligent model routing), Search API (real-time web retrieval, per-request billing), and Embeddings API (pplx-embed-v1 models). Check docs.perplexity.ai/docs/getting-started/pricing for current rates.
Is the original Sonar model still available?
No. The original Sonar Chat Completions API is deprecated as of September 27, 2026. It has been replaced by the Agent API. Migrate to the Agent API for continued access to search-augmented LLM capabilities.
What is the Perplexity Agent API?
The Agent API provides access to third-party models from OpenAI, Anthropic, Google, xAI, Z.AI, Moonshot AI, and NVIDIA at direct provider rates with no markup. It includes tools: web_search, fetch_url, people_search, and sandbox. Check docs.perplexity.ai for current tool rates.

Provider category context
DigitalOcean Gradient AI is a cloud, founded in 2012. Perplexity is a inference api, founded in 2022. The category difference means these providers serve partially overlapping use cases — compare the model lists and pricing tables above to find the best fit for your specific workload.
How to choose between them
Choose DigitalOcean Gradient AI if you need frontier model access: claude opus 4.7, gpt-5.4, gpt-5 via serverless inference. Choose Perplexity if you need agent api: access openai, anthropic, google, xai, z.ai, moonshot ai, nvidia at direct provider rates. For high-volume production workloads, run a cost comparison using the token pricing table above with your actual prompt/completion token ratio — the cheapest provider depends heavily on your input-to-output token ratio.
