# Carbon/Energy Estimator

> Free tool #21

Project the energy and CO2e of your monthly query volume — as a cited range across published measurements, never a single invented number.

## Three ways to use it

**Web** — the interactive page: https://telemeter.ai/tools/carbon-estimate

**MCP** — a `tools/call` on the public MCP server at https://telemeter.ai/mcp (tool name: `carbon-estimate`), read-only, no key required.

**REST** — `POST https://telemeter.ai/api/tools/carbon-estimate` with a JSON body matching the input schema below:

```json
{
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "type": "object",
  "properties": {
    "queriesPerMonth": {
      "type": "number",
      "exclusiveMinimum": 0,
      "maximum": 1000000000
    },
    "gridIntensity": {
      "type": "string",
      "enum": [
        "eu-average",
        "global-average",
        "custom"
      ]
    },
    "customGCo2PerKwh": {
      "type": "number",
      "minimum": 1,
      "maximum": 2000
    }
  },
  "required": [
    "queriesPerMonth",
    "gridIntensity"
  ],
  "additionalProperties": false
}
```
