Bulk Data (XBRL Fundamentals)
Download the XBRL fundamentals corpus as compressed flat files, regenerated nightly. Two independent families: the STANDARDIZED layer (`GET /api/v1/xbrl/bulk` — every company's in-force standardized line items + the identity dimension), and the AS-FILED facts store (`GET /api/v1/xbrl/bulk/facts` — the lossless per-fact corpus, split into shard files). Both are gzip ND-JSON (one JSON object per line). Discover a family's nightly manifest first (file list, row counts, SHA-256 digests), then stream the file(s) you need. The families have separate manifests and separate `latest` pointers, so an issue in one never affects the other.
