The level of service we hold ourselves to

The OPEN Government Data Act (Title II of the Foundations for Evidence-Based Policymaking Act of 2018) requires U.S. federal agencies to publish their data as open data: machine-readable, in an open format, under an open license, and listed in a public inventory. It covers federal agencies — not a state register like DORA’s, and not this site. We hold this register to that level of service anyway, and prove it line by line below.

Free of charge — every page and every machine file on this site is open, with no account and no key.
Machine-readable — manifest, field schema, real sample.
With an API — 5 callable tools, described with their input schema and wired into the page for an agent. The portfolio’s MCP server does not list this register yet.
Bulk download — ⚠️ not served free here: the raw data can be downloaded free from the source, named in the footer; our normalised version is described on the data page.

⚠️ No law requires any of this of us: it is a level of service we set ourselves, not a regulatory guarantee. Other public registers in the same format: catalogue.

An example that works, end to end

This register has no resolver: the example starts from the get_sample tool, which reads the served sample.
