Lookup osce · cod-cuadernos by RUC_CONTRATISTA

GET https://api.latinfo.dev/pe/osce/cod-cuadernos/ruc_contratista/{ruc_contratista}

A works notebook and contractor membership record. Coverage: Published construction notebooks associated with legal-entity contractors/consortium members. Lookup by ruc_contratista as a string, preserving leading zeros. Accepted syntax and normalization are defined by the contract below. Repeated rows can describe consortium membership; they are not independent contracts. Returns all records as an array. Import time is not observation time; inspect freshness headers. Add limit (1–500) and offset to retrieve an explicit page; without them the complete original array is returned. X-Total-Count gives the exact row count; follow Link rel=next to retrieve all pages.

Provenance and limitations

Coverage varies by country and public source. A missing field is not evidence that the underlying fact does not exist. Public registries may be delayed or contain source errors; inspect the returned evidence and source date before relying on a result.
