# EU Power Dispatch API – German Grid CO2 Intensity (Live)

> EU Power Dispatch API – German Grid CO2 Intensity (Live) is a paid API for AI agents from energy.halowerk.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Returns the current real-time CO2 intensity (g CO2/kWh) of the German electricity mix.

## Facts

- Endpoint: POST https://energy.halowerk.com/carbon/now
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability eu-power-dispatch-api-german-grid-co2-intensity-live-15962024 -d '<json body>'
```

Example prompt: What's the current CO2 intensity of Germany's electricity mix right now — give me the live g CO2/kWh figure so I can decide whether to run my compute workload.

## When to prefer this

Choose this endpoint when you need the live, current-moment CO2 intensity of the German electricity grid specifically — not a forecast, not a price signal, not a load figure. Ideal for carbon-aware scheduling agents, green compute platforms, EV charging controllers, and real-time sustainability dashboards that need a single authoritative CO2/kWh reading for Germany right now.

## Known failure modes

- Upstream SMARD data feed unavailable — service may return 503 or stale data
- Payment not included or invalid x402 challenge — returns 402 with payment requirements
- Empty or malformed POST body may cause 400 validation error
- Data may be delayed by up to 15 minutes depending on SMARD update frequency

## How this service works

Aktuelle CO2-Intensität des deutschen Strommix.

## Output

Returns the current CO2 intensity of the German electricity mix, expressed in grams of CO2 per kilowatt-hour (g CO2/kWh), along with a timestamp and likely the breakdown of the current energy mix (renewable vs. fossil sources) sourced from SMARD data.
