Runs synchronously; files over 100 MB return 413 and belong in a transfer. A repeat for an unchanged provider version returns the first copy with 200. Vault copies are stored as uploaded: call POST /vault/{id}/ingest/{objectId} to index them. Fetched copies are never exported by a link. ## OpenAPI ````yaml /openapi.json post /connectors/v1/fetch openapi: 3.1.0 info: title: Case.dev API description: >- The AI-native platform for legal technology.
