june_answerA grounded, **cited** answer from the graph — abstains rather than guesses
Parameters not published.
june_contextAn assembled context pack under a token budget
Parameters not published.
june_enrich**Pro:** background re-extraction of the canvas with the richer engine (idempotent; job + poll; 403 on free)
Parameters not published.
june_enumerateEVERY node matching a predicate — recall-complete "list ALL X" (not top-k)
Parameters not published.
june_ingestStructured node/edge ingestion
Parameters not published.
june_ingest_fileUpload one local file (pdf/docx/xlsx/csv/html/md/images/audio) from the operator-approved folder — *only exists when you set `JUNE_FILES_ROOT`*
Parameters not published.
june_neighborhoodThe graph around one node
Parameters not published.
june_rememberWrite a fact/note into the graph (becomes retrievable + citable immediately). Long texts run as an engine job: a result of `{state: running, job_id}` is collected with `june_remember(job_id=…)` — never re-send the text. Pasted text is content-addressed on the engine (v0.0.13), so a re-send of identical text upserts the same nodes; it cannot duplicate
Parameters not published.
june_resolveMaintenance: merge duplicate entities via reversible `same_as` edges (runs server-side; `strong_only=false` unlocks the semantic tier on Pro)
Parameters not published.
june_searchRanked evidence for a query (supports multi-hop)
Parameters not published.
june_subgraphA bounded subgraph export
Parameters not published.
june_usage**Usage receipts** — what June actually served, measured by a named tokenizer, never estimated. One receipt in full (`receipt_id`) or the window summary (`window`); a saving figure appears only over calls whose two provider-reported usages were really measured
Parameters not published.
