```json title="Run it · Response"
{
  "api": "https://api.sb/leaseline.app",
  "icp": {
    "$id": "https://api.sb/leaseline.app/icps/icp_Us2pM4gR8s",
    "$type": "ICP",
    "description": "US property managers with 20 to 400 units who still track rent in spreadsheets."

It extends the hub’s record call [`ICP.create`](https://startupbuilder.dev/business/nouns/icp/create), which every [ICP](https://startupbuilder.dev/business/nouns/icp) takes. It is one of the [Verbs](https://startupbuilder.dev/business/nouns/verb) of [Prospecting](/code/apps/prospecting#verbs).

## Inputs
| Name | Type | Default | Meaning |
| --- | --- | --- | --- |
| `description` | `text` | Required | Who they are and what they do. |

The hub inherits this call on every Noun: it takes the ICP’s own Properties, listed on [the hub’s ICP page](https://startupbuilder.dev/business/nouns/icp).

## Outputs
| Field | Type | What `null` means |
| --- | --- | --- |
| `icp` | `ICP` | Never null: the ICP as the call leaves it. |

## Effects
**Action class**

None: no approval rule names it, so it runs within its seat’s Permissions and Limits

**Modes**

- `try`: Runs every check and returns the record as it would be; nothing is stored.
- `send`: Returns a pending Action at once; `ICP.created` fires when it is done.
- `do`: Waits for the Action to finish and returns the record.

**Idempotency**

Only with a key: the same `Idempotency-Key` and input return the first Action, and the same key with other input returns `409`.

**Saved or shared**

The ICP is saved as the call leaves it, with the Action that changed it.

**Emits**

`ICP.created` with `{ icp }`

**Performed by**

Whichever seat calls it

**Price**

Free on your own account: the platform charges nothing for the call.

## On each Venue
It acts on your own records and reaches no Venue, so every account answers the same way.

## What try does
Runs every check the call meets and returns the record as it would be; nothing is stored, sent or posted.

## Refuses when
The hub sets no guard of its own on this call: it refuses only on the shared checks every write meets (a missing record, a Permission the seat lacks).

## When it waits
Returns in one response; nothing waits.

## Example
In `send` mode the call returns its pending Action at once, and `ICP.created` delivers the result.

**Ask**

```text
Save my customer: US property managers with 20 to 400 units who still
track rent in spreadsheets.
```

**API**

```bash
curl -X POST "https://api.sb/leaseline.app/icps?mode=send" \
  -H "Authorization: Bearer $SB_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
  "description": "US property managers with 20 to 400 units who still track rent in spreadsheets."
}'
```

**CLI**

```bash
npx startup-builder do ICP.create --send --data '{
  "description": "US property managers with 20 to 400 units who still track rent in spreadsheets."
}'
```

`--send` returns the pending Action at once.

**MCP**

```json
{
  "name": "do",
  "arguments": {
    "mode": "send",
    "code": "return await $.ICP.create({ description: 'US property managers with 20 to 400 units who still track rent in spreadsheets.' })"
  }
}
```

**SDK**

```ts
import { $ } from 'startup-builder'

const result = await $.send.ICP.create({
  description: 'US property managers with 20 to 400 units who still track rent in spreadsheets.',
})
```


```json title="Response, in send mode"
{
  "mode": "send",
  "action": {
    "$id": "https://api.sb/leaseline.app/actions/action_Sd3kQ9vT2w",
    "operation": "ICP.create",
    "status": "pending",
    "reason": "running"
  }
}
```

To retry, send the same `Idempotency-Key`: the retry returns the first answer for $0. A new key reads again.
