## What it is
Harpoon is a Python CLI tool that aggregates open source intelligence and threat intelligence lookups across many services (Censys, crt.sh, CIRCL passive DNS, BinaryEdge, etc.) through a plugin system. It is configured with API keys and used from the terminal to gather information on domains, IPs, ASNs, and certificates.

## Use cases
- look up threat intelligence on an IP or domain from the command line
- query certificate transparency logs for a domain
- gather OSINT on an ASN
- check passive DNS records for a domain
- search cached versions of a webpage
- run reconnaissance during a security investigation

## When to choose
- you want a single CLI wrapping many OSINT/threat intel APIs
- you do threat intelligence research or incident response from the terminal
- you want a plugin-based tool you can extend with your own sources

## When to avoid
- you need a GUI or web dashboard for OSINT
- you want a fully automated pipeline rather than interactive CLI queries
- you cannot obtain API keys for the services you need

## Facets
- artifact type: cli-tool
