# UK Grid Carbon Intensity (Suverse Proxy)

> UK Grid Carbon Intensity (Suverse Proxy) is a paid API for AI agents from proxy.suverse.io, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).

Returns current Great Britain electricity grid carbon intensity — forecast and actual gCO2/kWh values plus an intensity index — via a keyless proxy of the official Carbon Intensity API.

## Facts

- Endpoint: POST https://proxy.suverse.io/v1/data/suverse-uk-carbon-intensity
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/uk-grid-carbon-intensity-suverse-proxy-b30a739c

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 uk-grid-carbon-intensity-suverse-proxy-b30a739c -d '<json body>'
```

Example prompt: What's the current carbon intensity of the Great Britain electricity grid right now — give me the gCO2/kWh figures and the intensity band so I can decide whether to kick off this compute job.

## When to prefer this

Choose this endpoint when you need keyless, zero-authentication access to live GB grid carbon intensity data without managing your own API credentials. It is ideal for AI agents that need to make scheduling decisions based on grid cleanliness, or for sustainability dashboards requiring real-time gCO2/kWh readings. Prefer it over querying the Carbon Intensity API directly when you want a consistent, paid-proxy interface that fits into an x402 micropayment workflow.

## Known failure modes

- Upstream Carbon Intensity API unavailable or rate-limited — proxy may return 502/503
- No actual reading available yet for the current half-hour period — forecast value returned instead
- Malformed POST body causing 400 error even though no meaningful input is required
- Stale data if the upstream API has not refreshed its half-hourly update

## How this service works

Current Great Britain electricity grid carbon intensity from the official Carbon Intensity API, no key. Returns forecast and actual gCO2 per kWh and an intensity index. For AI agents scheduling compute for lower carbon and energy analytics.

## Output

Returns the current carbon intensity data for the Great Britain electricity grid, including: the forecast gCO2/kWh value, the actual measured gCO2/kWh value (when available), and an intensity index string (e.g. 'very low', 'low', 'moderate', 'high', 'very high') indicating the current cleanliness of the grid.
