# Seeded Synthetic Artifact Generator

> Seeded Synthetic Artifact Generator is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.10001/call, status unknown (last checked 2026-10-16).

Generates 16–256 synthetic sine/noise samples with seeded LCG noise and configurable artifact patterns (blinks, spikes, dropouts) for testing purposes

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability seeded-synthetic-artifact-generator-200005ca -d '<json body>'
```

Example prompt: Generate 128 synthetic noise samples using seed 42, a sample rate of 256 Hz, frequency of 10 Hz, amplitude '1.0', noise amplitude '0.2', and inject 2 blink-like pulse artifacts — I need reproducible toy test data labeled as synthetic.

## When to prefer this

Choose this endpoint when you need deterministic, reproducible synthetic waveform data with precisely controlled and labeled artifacts for unit testing, CI pipelines, or algorithm validation. It is ideal when you need seeded randomness so tests are repeatable, and when you want artifact positions explicitly declared rather than inferred. Not suitable for physiological simulation, real sensor data, or research-grade datasets.

## Known failure modes

- sampleCount outside 16–256 range returns validation error
- sampleRateHz outside 16–4096 range returns validation error
- seed exceeding 4294967295 returns validation error
- more than 8 artifact definitions provided returns validation error
- dataClass not set to 'synthetic' returns validation error
- amplitude or frequencyHz strings exceeding 13 characters return validation error
- malformed artifact definitions return schema validation errors

## How this service works

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.

## Output

Returns an array of 16–256 floating-point synthetic samples in arbitrary units generated by a seeded LCG noise function combined with a sine wave, plus a parallel array of artifact labels indicating which samples contain declared blink-like pulses, single-sample spikes, or dropouts. Results are retained for 24 hours; minimal receipt metadata is retained for 90 days.
