# Ambolt DK CO2 Intensity

> Ambolt DK CO2 Intensity is a paid API for AI agents from api.ambolt.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-11).

Returns the current and 24-hour CO2 emission intensity (grams CO2 per kWh) for Danish electricity price areas DK1 or DK2, sourced from Energinet's open dataset.

## Facts

- Endpoint: GET https://api.ambolt.dev/v1/dk-co2-intensity?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-11
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/ambolt-dk-co2-intensity-dee0322e

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 ambolt-dk-co2-intensity-dee0322e
```

Example prompt: What's the current CO2 intensity of the Danish electricity grid in western Denmark (DK1)? I want the latest reading in grams of CO2 per kWh along with yesterday's 24-hour average.

## When to prefer this

Use this endpoint when you need real-time or near-real-time CO2 emission intensity specifically for the Danish electricity grid (DK1 or DK2), particularly for energy scheduling, sustainability reporting, or carbon-aware computing workflows targeting Denmark. It is a pay-per-call micropayment endpoint ideal for agents that need on-demand spot checks without a subscription.

## Known failure modes

- Invalid area value (not DK1 or DK2) returns a validation error
- Upstream Energinet API unavailable may return available:false or an error response
- Payment not settled (x402 flow incomplete) returns HTTP 402
- Stale data if Energinet feed is delayed, reflected in fetchedAt timestamp

## How this service works

Pay-per-call data tools for developers and AI agents: company registers, documents, tenders, rates and on-chain facts as MCP tools, x402 endpoints and Apify Actors.

## Output

A JSON object containing: the price area queried, the latest CO2 intensity reading (grams CO2/kWh) with its Danish-local timestamp, a 24-hour summary with average intensity and the cleanest and dirtiest hour within that window, data availability flag, fetch timestamp, and source attribution to Energinet under CC BY 4.0.
