## プロジェクトの歴史と使われ方

Chaos Client is ProjectDiscovery's command-line and Go library client for the Chaos DNS dataset API, used to query subdomains for a domain with a ProjectDiscovery Cloud API key.

### プロジェクトの歴史

ProjectDiscovery published chaos-client as a small Go client around its Chaos dataset API. The public GitHub repository was created in 2020, and its README describes the tool as a client for the Chaos dataset API with both CLI and library usage.

### 採用の歴史

Adoption is tied to ProjectDiscovery's security-tool ecosystem: users install the `chaos` executable with `go install`, Homebrew distributes it as `chaos-client`, and Nix packages it as `chaos` according to the supplied package-manager facts.

### 使われ方

The CLI queries a domain for subdomains, can read domain lists, emit JSON, write output files, show counts, and use `PDCP_API_KEY` or `-key` for ProjectDiscovery Cloud authentication.

### パッケージ好きにとっての重要性

For package collectors, chaos-client is a typical modern Go security CLI: a thin API client, a single executable, source installs via `go install`, and package-manager aliases that differ from the upstream repository name.

### タイムライン

- 2020: Public GitHub repository created for projectdiscovery/chaos-client.
- 2020: Early v0.1.x tags established the Go CLI client line.
- 2026: Repository metadata still shows active maintenance and the README documents ProjectDiscovery Cloud API-key usage.

### Related projects

- ProjectDiscovery's Chaos service provides the dataset/API that this client queries.
- Other ProjectDiscovery reconnaissance tools such as subfinder and httpx commonly appear in the same security automation workflows, though they are separate projects.
