# GENESIS Agent Tools — Point-in-Time Leakage Detector

> GENESIS Agent Tools — Point-in-Time Leakage Detector is a paid API for AI agents from genesis-agent-tools.genesisagenttools.workers.dev, paid per call via x402, $0.04/call, status unknown (last checked 2026-10-01).

Detects point-in-time data leakage in a set of rows by checking whether any values expose information that would not have been available as of a specified cutoff date.

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 genesis-agent-tools-point-in-time-leakage-detector-cd55dcc7 -d '<json body>'
```

Example prompt: Check these training rows for point-in-time leakage as of 2023-06-30 — I want to know which rows contain values that wouldn't have been known by that date, and how many leaks there are total.

## When to prefer this

Choose this endpoint when you need to programmatically detect temporal/point-in-time leakage in structured row data before training ML models, running backtests, or validating feature pipelines. It is purpose-built for agentic workflows that need pay-per-call leakage auditing without standing up dedicated infrastructure. Prefer this over manual inspection when row volumes are moderate and you need a structured leaks list with a count.

## Known failure modes

- Missing required 'rows' field — returns validation error
- Missing required 'as_of' date field — returns validation error
- Malformed or unparseable 'as_of' date string — returns format error
- Empty rows array — returns zero leaks with no meaningful analysis
- Payment not provided or insufficient USDC — returns HTTP 402 requiring x402 payment of $0.04
- Rows array contains non-date-comparable values — may return partial or incorrect leakage detection

## How this service works

Pay-per-call x402 APIs for autonomous agents on Base USDC: API compatibility analysis, bounded HTTP/JSON workflows, URL evidence analysis, crypto price consensus, and agent/MCP readiness checks.

## Output

Returns a JSON object containing a 'leaks' array listing the specific rows or fields that leaked future information, and a 'leakage_count' integer summarizing the total number of detected leaks.
