How this service works
Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.
Output
Returns a JSON object with the current half-hour time window (from/to in ISO 8601), the actual carbon intensity in gCO2/kWh, the forecasted carbon intensity in gCO2/kWh, and a qualitative index label (e.g. 'low', 'moderate', 'high', 'very high').
Example use cases
Eco-aware appliance scheduling
“Is the electricity grid running clean right now? I want to know if the carbon intensity is low before I start my dishwasher or EV charger.”
Real-time sustainability dashboard
“Pull the current carbon intensity of the grid for me — I need the actual gCO2/kWh value and whether the index is low, moderate, or high for our sustainability dashboard.”
Green energy task timing
“Check the grid carbon intensity right now and tell me if this is a good moment to run our energy-intensive batch compute jobs from a carbon footprint perspective.”
Technical details
Endpoint
GEThttps://anibalb.duckdns.org/x402/carbon-intensity?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a no-account, pay-per-call lookup of real-time UK grid carbon intensity without API key setup. Ideal for agents running sustainability checks, scheduling energy-intensive workloads during low-carbon windows, or feeding green energy metrics into dashboards. Best when you need both actual and forecasted intensity in a single call.
Side effects
- Upstream carbon intensity data source unavailable — returns 5xx error
- Payment not included or invalid x402 USDC payment — returns 402 Payment Required
- Stale data if upstream National Grid API is delayed
- No parameters to filter by region — returns national aggregate only
