find_evidenceAnswers "what does X do?" and "does X affect Y?" for a supplement, nutrient, drug, food compound or plant (for example "does magnesium help sleep?", "what is creatine shown to do?", "omega-3 and triglycerides"). Pass the substance as query and the effect or outcome asked about,…
search_nodesLooks up the node id for a compound, protein, organism or outcome by name or synonym (for example "CoQ10", "caffeine", "CYP1A2", "sleep"). Use it to get the id that get_findings, get_finding, get_relations, get_reactions and reach take; for a question about what a substance does…
get_findingsLists the curated study findings for one node by id, from search_nodes: for a compound, organism or material, what it has been shown to affect; for an outcome, which compounds have been studied against it. Use it to browse a node by id. For a question in words, such as "does X h…
get_findingExplains one finding by its finding id: the claim, its evidence strength and what that level means, the verbatim quote, the study design and the paper, and evidence_strength_reasons, each rule that set the level in order, and what the assessment does not weigh. The finding id is…
get_relationsLists what public reference databases (Reactome, UniProt, Rhea, ChEBI and others) record about one node by id, from search_nodes: transporters, enzymes, pathways, expression. Every row is assertion_class 'inferred': a hypothesis about how a compound could act, not a result anyon…
get_reactionsLists the biochemical reactions from Rhea and Human-GEM that a compound is a substrate or product of, or that a protein (enzyme) catalyses or transports, by node id from search_nodes. It lists reactions and does not answer a route question: for "can X become Y" or "what can X be…
reachAnswers a route question: "can X become Y in the body" (give from_id and to_id) and "what can X become" (give only from_id). Both ids are compound node ids from search_nodes, so a question that names two compounds needs one search_nodes call for each first. It searches the react…
