Connect SendGrid to Lob
When New bounce fires in SendGrid, your agent runs Create Address in Lob. 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.

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
SendGrid and Lob, answered
What can start an automation from SendGrid?
Any of SendGrid's 4 triggers in the catalog, including New bounce, New global suppression, New or updated recipient and New suppressed email. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Lob when something happens in SendGrid?
Any of Lob's 40 actions, including Create Address, Create Bank Account, Create Template and Send Check. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Lob to SendGrid?
Lob has no triggers in the catalog today, so automations start in SendGrid. If you need the other direction, ask: your agent reads Lob's API documentation and adds it.
Do I have to build a connector for SendGrid or Lob?
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 SendGrid and Lob 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.
