Integration
Connect Castos and SEMrush
When New Episode fires in Castos, your agent runs Create Project in SEMrush, or Completed Site Audit in SEMrush to Find Private Subscriber by Email in Castos. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.
What do you want Castos and SEMrush to do together?
Ask the assistant
Connect your AI client
Give your AI client this address.
https://mcp.apiant.aiOne connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

Questions
Castos and SEMrush, answered
What can start an automation from Castos?
Any of Castos's 3 triggers in the catalog, including New Episode, New Podcast and New Private Subscriber. Describe the moment in plain language and your agent picks the right one.
What can your agent do in SEMrush when something happens in Castos?
Any of SEMrush's 7 actions, including Create a New Site Audit Campaign, Create Project, Get Overview Report and Get Site Audit Campaign Info. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from SEMrush to Castos?
Yes. When something happens in SEMrush, your agent can act in Castos too. This page covers both directions: SEMrush's triggers and Castos's actions are listed here as well.
Do I have to build a connector for Castos or SEMrush?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use Castos and SEMrush without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
