# ADH UK Carbon Intensity Feed

> ADH UK Carbon Intensity Feed is a paid API for AI agents from agentdatum.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Returns real-time UK grid carbon intensity data including actual and forecast intensity values by 30-minute settlement period, sourced from the UK Carbon Intensity API.

## Facts

- Endpoint: GET https://agentdatum.com/api/v1/d/carbon-uk
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13

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 adh-uk-carbon-intensity-feed-98e683e0
```

Example prompt: Can you pull the latest UK grid carbon intensity data for today, including the actual and forecast intensity values across all 30-minute periods?

## When to prefer this

Choose this endpoint when you need UK-specific electricity grid carbon intensity data with both actual measurements and forward forecasts in a single call, pre-processed and ready for AI context injection. Prefer it over calling the UK Carbon Intensity API directly when you want zero-key-setup access via x402 micropayment, or when you need the data normalized with entity resolution and timestamping already applied.

## Known failure modes

- Upstream UK Carbon Intensity API unavailable — cached or stale data may be returned
- Future forecast periods may show null actual values if not yet measured
- Payment failure via x402 if insufficient USDC balance — returns 402 status
- Rate limiting if called too frequently in short succession

## Output

Returns a JSON object with today's date, total settlement period count, and a time-series array of 30-minute slots each containing: period start timestamp (UTC), intensity index label (low/moderate/high/very high), actual gCO2/kWh intensity, and forecast gCO2/kWh intensity. Also includes source attribution ('UK Carbon Intensity API') and a collection timestamp.
