Can I use this data in my own product?

Inside your own work

Use what you reveal however you like in your own research, client work and internal tooling. That is what the directory is for, and no plan restricts it.

Republishing is different

Wholesale republication of the directory, or reselling it on as your own feed, is not what a Pro subscription covers. The whole asset here is the aggregation work: the archive checks, the link verification, the spam screening and the scoring. Handing that over as a copy would be handing over the product.

Building on the API

Every plan includes a REST API and an MCP endpoint precisely so the data can sit inside something you build, and the Business plan adds a change feed for keeping a copy in step. Having an API key is not itself permission to republish: the rule above is unchanged, and a name whose tier is not open stays inside your own work. If what you are building is customer-facing, tell us what you have in mind: get in touch and we will sort out terms rather than leave you guessing.

Expired domains, cited by AI

Own a domain ChatGPT and Google already cite

Every listing carries its Agent Citability score, verified referring domains from our web crawl, site history and age, spam filtered out. Reveal a name, register it at any registrar, and put that authority behind your own site.

Availability is re-checked the moment you reveal a name. They go once someone else registers them.
