# Estimate what OpenEmail costs

Every plan priced for a usage, and the cheapest one that fits.

`GET /tools/cost`

## GET /tools/cost

Every plan priced for a usage, and the cheapest one that fits.

## Example

Needs no scope. `sends` is emails a month, `aiActions` AI actions a day, and `interval` is `month` or `year`. Every amount is in US cents per month, and a plan that cannot carry the usage has `fits: false` and names why in `blockers`.

**curl**

```
curl "$OE/tools/cost?sends=25000&domains=2&people=4&aiActions=30" -H "$AUTH"
```

**Response**

```
{
  "object": "cost_estimate",
  "interval": "month",
  "need": { "sends": 25000, "domains": 2, "people": 4, "aiActions": 30 },

    {

    }
  ],
  "cheapest": "starter"
}
```

> These are the prices of the cost calculator on the OpenEmail website, and it reads nothing in the workspace. `cheapest` is null when no plan fits.
