How this service works
Cheapest end-to-end x402 purchase test. Always returns a 402 challenge without payment and the current full NegPrice decision after a valid USDC payment.
Output
After a valid USDC micropayment via x402, the endpoint returns the current full NegPrice decision — a signal indicating whether EU/German spot electricity prices are negative — along with supporting spot-market context sourced from ENTSO-E and SMARD. Without payment, it returns a standard HTTP 402 challenge.
Example use cases
Flexible load scheduling decision
“Should I run my compute workload right now based on current EU electricity prices? Check the live NegPrice decision and tell me if prices are negative.”
x402 micropayment integration test
“Test the x402 payment flow against the EU Power Dispatch paid sample endpoint — confirm you get the 402 challenge without payment, then pay and show me the NegPrice decision you get back.”
Battery dispatch trigger
“Is there a negative price event happening on the German grid right now? Fetch the current NegPrice decision so I can decide whether to charge my battery storage.”
Technical details
Endpoint
GEThttps://energy.halowerk.com/demo/paid-sampleWhen to prefer
Choose this endpoint when you need the current German/EU negative-price decision in real time and are operating within an x402-capable agent framework that can handle USDC micropayments automatically. It is ideal for flexible-load agents, battery dispatch systems, or developers testing x402 payment flows against a live, low-cost target.
Side effects
- 402 returned without payment — expected behavior, not a true error
- Payment validation failure — if USDC amount or x402 header is malformed, payment is rejected
- Stale or unavailable market data — upstream ENTSO-E/SMARD feed may be delayed
- Network timeout — endpoint unreachable transiently
- Invalid HTTP method — only GET/HEAD/DELETE accepted
