Every row carries a source URL and a read date. Cite the edition, not the home page.

## Using the data

The files are free to reuse with attribution under the [terms](https://agentreadycheckout.com/terms). Status values are live, pilot, announced, not\_supported and no\_statement. A no\_statement row means nothing published was found on the read date, which is not the same as a statement that the thing is unsupported. The [method page](https://agentreadycheckout.com/method) defines every field. The ids in the matrix files are spelled out, with each name, operator and page, in [the matrix names file](https://agentreadycheckout.com/data/matrix-names-2026-11-04.json).
