nomic_get_userread-onlyFetch the account the API key belongs to, including the organisations it can access. Start here — the organisation slug feeds the other tools. Atlas: GET /v1/user.
nomic_get_organizationread-onlyFetch an organisation by slug, with the datasets it holds. Atlas: GET /v1/organization/{slug}.
nomic_get_datasetread-onlyFetch a dataset (Atlas calls it a project) by id — its schema, size, indices and projections. Atlas: GET /v1/project/{id}.
nomic_get_dataset_by_slugread-onlyFetch a dataset by organisation slug and dataset slug — the human-readable path, and usually easier than finding the UUID. Atlas: GET /v1/project/{organization_slug}/{project_slug}.
nomic_nearest_neighbors_by_idread-onlySemantic search: given the ids of records already in a dataset, return their nearest neighbours in embedding space, with distances. This is what Atlas is for — finding what resembles what across unstructured data. Needs a BUILT index; if the map is still building the call fails with a 500, so check nomic_get_index_job. Atlas: POST /v1/project/data/get/nearest_neighbors/by_id.
nomic_get_index_jobread-onlyFetch the status of an index-building job. Atlas indexes take time to build, and a vector search against an unbuilt map fails — this is how you tell which it is. Atlas: GET /v1/project/index/job/{job_id}.
nomic_get_projection_schemaread-onlyFetch the field schema of one projection — the columns available on its records. Atlas: GET /v1/project/projection/{projection_id}/schema.
nomic_list_tagsread-onlyList the tags defined on one projection — the labelled selections a person made on the map. Atlas: GET /v1/project/projection/tags/get/all.
nomic_get_tag_statusread-onlyCheck whether a tag has finished computing its membership. A tag that is still building returns partial results. Atlas: GET /v1/project/projection/tags/status.
