## 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-national-grid-carbon-intensity-current-forecast-actual-c77cf609 -d '<json body>'
```

Example prompt: What's the current carbon intensity of the Great Britain electricity grid — is it low, moderate, or high right now, and how does the actual compare to the forecast?

## When to prefer this

Use this endpoint when you need a quick, no-parameter snapshot of the current GB national carbon intensity, including both the actual and forecast figures and a human-readable index. Prefer this over the date-parameterised sibling endpoint when you only need the live current reading rather than half-hourly historical or future data.

## Known failure modes

- Upstream Carbon Intensity API unavailable — proxy returns 5xx error
- Stale data if the upstream source has not updated recently
- Network timeout if the clonecho relay is overloaded
- Payment failure if the x402 USDC payment of $0.02 is not correctly submitted

## How this service works

Current Great Britain grid carbon intensity forecast/actual and index (no params). Returns JSON.

## Output

A JSON object containing the current national carbon intensity for the GB grid, including the actual gCO2/kWh value, the forecast value, a descriptive index label (e.g. 'low', 'moderate', 'high', 'very high'), and the relevant time window.
