Time your agents with Grid402
Grid402 is an HTTP API for the world's electricity grid. Every request to a paid endpoint returns
402 Payment Required until you attach a signed
x402 payload. Free routes (health, schema, demo-tier mix) work without payment.
Primary product
5-minute generation mix and the carbon intensity computed from it.
Hourly mix is commoditized. Sub-hourly mix is what makes 24/7 CFE verification, hourly CBAM reporting, and DePIN slashing computationally possible — and it's what no other vendor sells per-call. Spot price is shipped alongside, but the moat is the mix.
Quickstart
Make your first paid call in 60 seconds — starts with /mix, the primary signal.
Endpoints
openapi.jsonAll routes — mix (primary), emissions (derived), spot price (bundled), combined.
x402 protocol
How HTTP 402 + USDC on Base settles each call.
Grid operator coverage
coverage.jsonCAISO, ERCOT, NESO (GB), KPX, AEMO — Independent System Operators (not the standards body). Granularity, freshness, source URLs.
