Both 404s share one envelope:\n  `{\"_meta\":{\"args\":{...all request params echoed back...}},\"message\":\"<English sentence>\"}`.\n\n## `limit` barely shrinks the payload — per-dataset metadata is embedded on every call\n\n`limit` caps the **series count**, not the response size: `/v22/datasets/IMF?limit=5` (5\ndatasets) was **1,134,863 bytes**, and `/v22/series/IMF/BOP?observations=1&limit=1` (ONE\nseries) was **1,086,187 bytes** — because every response embeds the full dataset-level\n`attributes_labels`, `attributes_values_labels`, and (implied) dimension codelists regardless\nof how many series/observations are actually requested.
