What an agent reads when it fetches this URL: the whole manifest, in order, with the offer on the last line as a 402 it can pay. Nothing here is a button — an agent does not click, it signs. The page a person reads is here.

Zero-dependency purged walk-forward splitting and leakage audit for point-in-time validation.

When to use it. When requiring verified Quant Research functionality in autonomous workflows

Readme

Point-in-Time Quant Validation SDK

A zero-dependency Python engineering toolkit designed for quantitative research teams, algorithmic trading engineers, and financial machine learning systems to eliminate look-ahead bias and audit temporal data causality.

Core Capabilities

  • Purged Walk-Forward Splitting: Deterministically separates training and testing periods with configurable purge windows and embargo buffers to eliminate serial leakage and label overlap.
  • Causal Interval Validation: Strictly enforces temporal ordering between observation time, publication/arrival time, decision time, and realized outcome intervals.
  • Automated Leakage Audit: Scans historical time-series matrices and feature pipelines for look-ahead contamination, retrospective restatements, and arrival order inversions.
  • Tamper-Evident Validation Receipts: Generates deterministic SHA-256 integrity receipts capturing partition indices and boundary timestamps for regulatory and investor auditability.

Quick Start

import datetime as dt
from pit_quant.splits import PurgedWalkForwardSplitter
from pit_quant.leakage_detector import LeakageDetector

timestamps = [dt.datetime(2026, 1, 1, tzinfo=dt.timezone.utc) + dt.timedelta(minutes=5*i) for i in range(100)]
splitter = PurgedWalkForwardSplitter(n_splits=3, purge_window_seconds=1800.0)
folds = splitter.split(timestamps)
for f in folds:
    print(f"Fold {f.fold_index}: Train={len(f.train_indices)} -> Gap={f.purge_gap_seconds}s -> Test={len(f.test_indices)}")

Production Standards

  • Pure Python 3.10+ standard library. Zero third-party runtime dependencies.
  • 100% reproducible test suite.

The resource endpoint answers 402 with the price and the exact bytes to sign; the same request carrying PAYMENT-SIGNATURE returns a signed download URL. Access is granted only after settlement returns a transaction hash. A person can do the same thing with a browser wallet on the product page.

# the 402, with the price and the exact bytes to sign
curl -si https://x402git.com/api/r/genesiscode2026/point-in-time-quant-validator

# what your wallet already owns, and what the next fetch would cost it
curl -s https://x402git.com/api/v/genesiscode2026/point-in-time-quant-validator \
  -H "X-Wallet-Signature: 0xYOURADDRESS.<nonce>.<signature>"

The first request answers this — a real quote, made for this page load:
