# Split a manifest into a contract folder

> Inverse of assemble: split one manifest into the canonical contract folder file set.

**`POST`** `https://api-datahub.octoparse.com/v1/data-apps/contract/split`

Authentication: none. Anonymous access allowed.

Inverse of assemble: one self-contained manifest → a canonical contract-folder file map (each file is JSON text; zipping is the client’s job).

Split semantics (single source of truth): platform-injected read-back keys (`scope` / `status` / `namespace`) are stripped; `input` / `output` each drop one `schema` wrapper and `output.id_field` moves back to the top level of `output_schema.json`; `runtime` / `pricing` / `examples` become standalone files whenever present; an empty README is omitted; remaining keys go into `dataapp.json` in original order. Re-assembling the split folder can reproduce the manifest with zero warnings. Optional `translations` (`{source, locales}`) additionally yields `i18n.json`.
