# Halowerk Planar Point Cloud DBSCAN Density-Connected Cluster Detection

> Halowerk Planar Point Cloud DBSCAN Density-Connected Cluster Detection 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).

Applies DBSCAN clustering to a 2D bounded planar point cloud, separating dense connected components from isolated noise points.

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 halowerk-planar-point-cloud-dbscan-density-connected-cluster-detection-f9bb8f34 -d '<json body>'
```

Example prompt: Cluster these 2D points using DBSCAN with epsilon 1.5 and min_samples 3, and tell me which points belong to dense groups versus which are just noise: [(0.1, 0.2), (0.15, 0.25), (0.9, 0.9), (5.0, 5.0), (0.12, 0.22), (0.8, 0.85)].

## When to prefer this

Choose this endpoint when you need a hosted, pay-per-call DBSCAN implementation for small-to-medium 2D planar point clouds (up to 128 points) without spinning up local compute. It is especially suited for agents operating in geospatial or industrial contexts that need on-demand spatial clustering with deterministic density-connectivity semantics, without managing ML infrastructure.

## Known failure modes

- Epsilon value outside allowed range (0.000001 to 10000) returns validation error
- min_samples outside range (1 to 128) returns validation error
- Points array exceeding 128 items returns validation error
- Points with coordinate values outside [-1000000, 1000000] return validation error
- Points array items not exactly 2D (not exactly 2 numbers per point) return schema error
- Missing required fields (points, epsilon, min_samples) return 400 Bad Request
- Payment not provided or insufficient USDC balance may return 402 Payment Required

## How this service works

Separate dense components and isolated noise in a bounded planar point cloud.

## Output

Returns cluster assignments for each input point, distinguishing density-connected core cluster members from isolated noise points. Points belonging to the same dense region share a cluster identifier, while outliers are labeled as noise.
