Three calls cover what Evidencesway does, and a fourth tells you what each one costs. The responses are real answers recorded on 1 November 2026, trimmed to the main fields. Counts grow as the research index grows.

Evidence for an ingredient and an outcome
Use it for the core of a claim check: how much research there is, what kinds of study, and what the most relevant studies found. In Evidencesway, this is a claim card. Send claim; limit (default 16) sets how many studies are picked for reading.
query.lane_counts: papers on the ingredient, on the outcome, and on both together (intersection).corpus_stance: for the papers on both, the kinds of paper (contribution) and how they frame their finding (sides).documents: the studies picked, each with its kind (tier, such as trial or meta_analysis), its strength, what it found for the claim (stance) and a quote checked word for word (quote_verified).tally: how many of the studies read support, contradict or qualify the claim; tier_weighted counts stronger kinds of study for more.meta.coverage: when partial is true, part of the index was offline and counts are lower bounds.

The strongest single study
Use it for one study to show next to a claim: the best match, its kind of study, the finding in the paper’s own words and who wrote it. Send claim. The full answer also carries a ready-made HTML citation.

What disagrees, and how mixed it is
Use it for a fair answer when studies disagree: it looks for studies on both sides on purpose and reads them, then adds a plain note on how to word the claim (recommendation). Send claim; limit (default 16) sets how many studies are picked.
