Neural Synthetic Artifacts

by Seeded synthetic artifact test p in Other

x402 APIPassing, checked 3 h ago

Generate 16–256 original synthetic sine/noise samples with seeded LCG noise and declared nonoverlapping blink-like pulses, single-sample spikes or dropouts. Returns artifact labels in arbitrary synthetic units. Toy test data only, not physiological simulation or third-party research data; no participant signals. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.10001.
