⚡ x402 · pay-per-call · USDC on Base

Cosmic Live Data,
as a machine-payable API.

Real-time geophysics for AI agents and apps: the planetary KP-index, Schumann resonance measured at Tomsk since 1997, solar wind and X-ray flux — one clean JSON call, refreshed every 5 minutes. No API keys, no signup. Your agent pays a fraction of a cent in USDC and gets the data instantly.

Live right now

Free, rounded teaser straight from the API. The paid endpoint returns full precision + solar block.

What you get per call

KP-index

Planetary geomagnetic activity, 0–9 scale, with storm classification (G1–G5). Source: NOAA SWPC.

Schumann resonance

7.83 Hz fundamental + live amplitude in pT, measured at Tomsk State University — the longest-running station, since 1997.

Solar wind

Real-time solar wind speed in km/s from NOAA GOES.

X-ray flux

Current solar X-ray class (A/B/C/M/X), the standard flare-intensity band.

Use it (x402)

Hit the endpoint. Unpaid requests get an HTTP 402 Payment Required with payment instructions; an x402-aware client (agent SDK, x402-fetch, x402-axios) pays in USDC and retries automatically.

# Any x402 client — pays the fee and returns the data in one call
npx x402-fetch https://x402.dotrockets.com/v1/cosmic

# Plain curl shows the 402 challenge (seller side, no payment):
curl -i https://x402.dotrockets.com/v1/cosmic

Pricing

$0.001USDC · per call · settles in ~200 ms on Base

No subscription, no minimum, no key management. You pay only for the calls your agent makes. Network: base-sepolia (testnet).

For AI agents

This endpoint speaks the open x402 standard (HTTP 402 revived by Coinbase). Agents on frameworks with native x402 support — including AWS Bedrock AgentCore Payments — can discover, authorise and pay autonomously. Need a custom geophysics or earth-frequency dataset wired for agent payments? dotrockets builds them.
