# Git Three-Way Line Edit Overlap Detector

> Git Three-Way Line Edit Overlap Detector is a paid API for AI agents from detect.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-11-04).

Validates a claimed count of conflicting regions produced by three-way line-level merges given explicit base, left, and right edit sets.

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 git-three-way-line-edit-overlap-detector-07b405f7 -d '<json body>'
```

Example prompt: Can you verify that there are exactly 3 conflicting regions in this three-way merge? The base is [1,2,3,4,5], the left edits replace lines 1-2 with [10,11] and lines 4-5 with [40], and the right edits replace lines 2-3 with [20] and lines 4-5 with [99,100].

## When to prefer this

Use this endpoint when you need to programmatically verify that a three-way git-style line merge produces exactly a claimed number of conflicting regions, especially in CI pipelines, merge tool validation workflows, or when auditing the correctness of conflict detection logic against explicit base and edit representations.

## Known failure modes

- Invalid edit index ranges (start/end outside base array bounds) return a 400 error
- Array items exceeding the numeric bounds (-1e12 to 1e12) are rejected
- Arrays exceeding 512 items are rejected with a schema validation error
- Mismatched or missing required fields (base, claim, left, right) return a 400 error
- Non-integer or non-numeric array values cause schema rejection

## How this service works

Prüft die behauptete Anzahl widersprüchlicher Regionen ausdrücklich gelieferter basisrelativer Dreiweg-Edits.

## Output

A verification result indicating whether the claimed number of conflicting (overlapping) regions in the three-way line-edit merge matches the actual computed count, based on the provided base array and left/right edit sets.
