• searchSearch the whole GreenCycle Compound Atlas by any name: cannabis compounds (THC, CBD, CBG, terpenes, flavonoids), receptors and enzymes (CB1, CB2, TRPV1, 5-HT1A, FAAH), medical conditions with an evidence grade (epilepsy
• fetchThe full text of one atlas record by the id that search returned ("compound:cbd", "target:CB1", "condition:epilepsy", "trial:NCT03883360", "cultivar:STRAIN0001"): what it is, the targets and effects with evidence grades,
• search_compoundsUse for lists of cannabis compounds: find the compounds mapped onto the human body (curated atlas records and database compounds with a measured, sourced value at a target placed in tissue) by name, chemical class, recor
• get_compoundUse for "what does THC, CBD or myrcene do in the body": the full record of one mapped compound by atlas id, Cannabis Compound Database id, name or PubChem CID. A curated record gives identity and structure identifiers, e
• compare_compoundsUse for "THC versus CBD" and similar questions: two to four compounds side by side, target by target, with each action, evidence grade, measured binding values and PubMed identifiers, the targets they share and the atlas
• get_targetUse for receptor questions: one receptor, ion channel or enzyme by name or gene (for example CB1, CNR1, TRPV1, GPR55, FAAH, CYP3A4): what it is, where it sits in the body, the compounds mapped to it with their action, ef
• list_structures_for_targetUse for "where in the body": the atlas body structures (organs and regions) that carry a molecular target: for CB1 and CB2 the qualitative receptor density (0 to 4, a teaching summary of the literature, not a measurement
• find_studiesUse for "what is the evidence" and "which studies": the PubMed studies the atlas cites for a compound, a target, a condition or a compound at one target, each with its PubMed link, what it supports (an effect at a target
• search_conditionsUse for "does cannabis help with ...": conditions on the atlas evidence ladder (substantial, moderate, limited, insufficient, evidence of no benefit): the grade and why, the systematic reviews and trials behind it by Pub
• list_trialsUse for clinical trial questions: registered trials from the atlas snapshot of ClinicalTrials.gov (trials whose intervention is named cannabis, a cannabinoid, cannabidiol, THC or a related medicine): identifier, title, s
• get_cultivarUse for strain chemistry: one cultivar from the laboratory measurements the atlas uses (Cannabis Compound Database values, mg per gram of dry flower), by CCD id or name: every atlas compound measured in it with the mean,
• citeA ready citation for one atlas record (compound, target or condition) or for the atlas as a whole: the canonical url, the citation line, a BibTeX entry, the version, the original papers to cite for its findings (PubMed l
• get_changesThe latest releases of the atlas data files: the version to cite, which datasets changed, records added and removed, and where the dated copy of each release lives. Example arguments: {"limit":3}.
• ask_atlasUse first for a plain question such as "does CBD help epilepsy", "where does THC act" or "what binds TRPV1": finds the compounds, conditions and receptors the question names in the atlas and answers only from those recor
