- The sample resolver identifies a pinpoint as found and returns the California citation as ca/rtc/19132.
Field notes
The displayed resolver example separates a citation's pinpoint from its normalized citation and reports whether that pinpoint was found. The coverage schedule spans statutes, regulations, agency materials, and decisions; it lists thousands of items for several collections, while marking New York's 20 NYCRR coverage as in progress. The page documents both REST and MCP interfaces, but says the three non-federal/non-California jurisdiction groups require an API key.
