Connect Hex to Signatureapi
When New Project Run fires in Hex, your agent runs Add ceremony in Signatureapi. 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 Hex and Signatureapi 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.

Open Settings, then AI, then MCP Servers, then Add Server, then Add Remote Server.
Setup guide (opens in a new tab)Codex and the ChatGPT desktop app
Open Settings, then MCP servers, then Add server, and choose Streamable HTTP. From the terminal, Codex takes the address with its own add command and then signs you in.

Questions
Hex and Signatureapi, answered
What can start an automation from Hex?
Any of Hex's 4 triggers in the catalog, including New Project Run, List Groups, List Projects and List Users. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Signatureapi when something happens in Hex?
Any of Signatureapi's 15 actions, including Update envelope, Update recipient, Add ceremony and Add deliverable. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Signatureapi to Hex?
Signatureapi has no triggers in the catalog today, so automations start in Hex. If you need the other direction, ask: your agent reads Signatureapi's API documentation and adds it.
Do I have to build a connector for Hex or Signatureapi?
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 Hex and Signatureapi 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.
