Ground a claim in evidence

A diagnosis without a treatment is a complaint. When the scorer says a claim is weak, references are the treatment: pull the real bill, the real Census figure, the real filing, and replace the vibe with a citation.

Query a corpus directly

Every reference corpus (Congress, Census, FEC, and more than a dozen others) exposes list and get operations, mounted at radiance.references.<corpus>.

bills = client.radiance.references.congress.list_bills(
    query="broadband infrastructure", congress=119
)

evidence = client.radiance.references.census.list_american_community_survey(
    get="NAME,B28002_001E", for_="county:*", in_="state:34"
)

Or ask in natural language

Most corpora also expose a query agent that answers a plain-English question and returns a grounded result.

answer = client.radiance.references.fec.query(
    "Total independent expenditures in NJ Senate races since 2024?"
)

Reference calls are bundled free at every tier. Grounding a claim never adds to your metered cost, because evidence should never be the thing you ration.
