Hello. As I am reading Sonar is moving to the Agent API and cannot reply there - will the OLD API remain available after 27 Sep or it will be off? Wondering about the deadline to migrate… anyone?

> Sonar is moving to the [Agent API](https://docs.perplexity.ai/docs/agent-api/migrate-from-sonar/overview). The Perplexity Agent API keeps grounded web search, and adds multi-step research, code execution, built-in tools, and access to multiple models through one API. On BrowseComp and WideSearch, Agent API more than doubles the best Sonar score. Sonar endpoints are fully available today and retire on September 27, in 45 days. See the Migration Guide for more details: [Migrate from Sonar to the Agent API](https://docs.perplexity.ai/docs/agent-api/migrate-from-sonar/overview).

Hello @Szymon,

Thank you for your question. The Sonar chat completions endpoint will retire on September 27. You will need to migrate to the Agent API responses endpoint before then.

Here is the migration guide - [Migrate from Sonar to the Agent API - Perplexity](https://docs.perplexity.ai/docs/agent-api/migrate-from-sonar/overview)

You can let your coding agent do the migration for you. Open it in the project you want to migrate and send it this:

```auto
Read https://github.com/perplexityai/api-platform-developers/blob/main/skills/migrate-sonar-to-agent-api/SKILL.md and install this skill, then use it to migrate this project from Sonar to the Agent API.

```
