# Reproducibility Manifest Builder

> Reproducibility Manifest Builder is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.010019/call, status unknown (last checked 2026-10-15).

Generates a reproducible research handoff manifest from supplied public or synthetic artifact contents, dependencies, algorithm version, random seed, and run parameters.

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 reproducibility-manifest-builder-38ea6c02 -d '<json body>'
```

Example prompt: Build a reproducibility manifest for my experiment run 'train-run-42' using algorithm version 'xgboost-1.7.3' with seed 271828 on public data — the artifacts are my model weights and training log, and I have two hyperparameter entries to include.

## When to prefer this

Choose this endpoint when you need to package a research run into a structured, shareable reproducibility manifest — especially when working with public or synthetic datasets and needing to declare algorithm version, random seed, and artifact inventory. Not suitable for independent third-party certification; use for researcher-authored provenance documentation and handoff.

## Known failure modes

- Missing required algorithmVersion field returns validation error
- Artifacts array empty or exceeds 64-item limit returns schema rejection
- Seed value outside 0–4294967295 range fails validation
- dataClass enum value not 'public' or 'synthetic' causes rejection
- runId exceeding 80 characters returns length validation error
- Parameters array exceeding 32 items causes rejection

## How this service works

Prepare a reproducible research handoff from supplied public or synthetic artifact contents, dependencies, algorithm version, seed and Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

A structured reproducibility manifest document capturing artifact references, algorithm version, random seed, run ID, parameters, and data class — formatted as a handoff record enabling others to understand and re-run the described experiment using the same declared inputs.
