Your agents, from your own code. With a key you control.

Create an API key, then manage your agents from a script or an AI app: read conversations, add knowledge, change a setting and ask a question. A key acts as the person who made it, and only with the access you chose.

The API is on Growth and up. Growth allows 120 reads and 30 writes a minute for each key, and 5 keys.

What it does for you.

  • From Growth

    Make a key and choose what it can do

    Create a key under Workspace › Developers › API keys. Pick Read only, Build and manage, Zapier or Custom, and when it expires. You see the key once, and you can rotate or revoke it later.

  • From Growth

    Call it from your code

    Send your key to https://api.hiy.ai/v1. Create and publish an agent, add a source, read conversations and unanswered questions, teach an answer, or ask an agent.

  • From Growth

    Change a setting, see it first

    Propose a change and read the value before and after. Apply it, or discard it. An earlier version can be restored if you want it back.

Questions people ask first.

What are the limits?

Growth: 120 reads and 30 writes a minute for each key, 5 keys. Calls are counted per key, reads and writes apart, with no monthly cap. A call past the limit answers 429 with how long to wait.

The API reference

Which plan do I need?

Starter ($19.99 a month) covers the website chat, the Inbox and handover. Growth ($40 a month) adds the API and its keys.

Does asking an agent cost anything?

Yes. An ask costs credits, like a visitor’s question. Every other call is free, and tests use your free daily test replies.

Limits and retries

Can a key do more than I can?

No. A key acts as the person who made it, on the agents they own, and only with the access you picked.
