/projects/{slug}/environments/{environmentSlug}/duplicateCopies an environment and all its variables, ciphertext included, into the same project in one transaction. Takes no request body. The copy is named <name> (Copy) (truncated to 50 characters) with a slug derived from that name and suffixed -2, -3, ... until free within the project, falling back to a random 6-character suffix after enough collisions. Needs both environments:write and variables:write. The per-project environment allowance is checked before any copying, so a 402/409 leaves nothing behind. Unlike the project duplicate route this is not blocked for project-restricted keys, because the copy stays inside a project the key already covers. exposed always comes back false on this response regardless of the source environment.
Requires the environments:write or variables:write scope.

}401Unauthorized
auth.api_key_required- theAuthorizationheader is missing, or its value does not start withev_sk_.auth.api_key_not_found- the key is unknown, inactive or revoked.auth.api_key_user_missing- the key is valid but its owner no longer exists.auth.api_key_owner_not_member- the key's owner is no longer a member of the key's workspace.
402Payment Required
plan.upgrade_required - the project already holds its plan's environment allowance, or the project itself is locked. data carries { limit, current } in the allowance case.
403Forbidden
auth.scope_missing- the key lacks environments:write or variables:write.auth.key_project_restricted- the project is not in the key's project allowlist.auth.product_restricted- the project's product is private and the key owner holds no grant on it.auth.workspace_two_factor_required- the workspace requires two-factor authentication and the key's owner has not turned it on.
404Not Found
project.not_found- no project matches in scope for this key.environment.not_found- no environment with that slug lives in the project.
409Conflict
project.ambiguous_product- the project slug resolves to projects in more than one product; retry with?product=<productSlug>.plan.limit_reached- reserved for a plan whose environment allowance sits at or above the 1,000 fair-use cap. No current tier can trigger it: Free, Dev and Team fail with 402plan.upgrade_requiredat their own allowance instead, and Enterprise is unlimited and never hits a plan limit.datacarries{ limit, current }.project.not_found- the project was deleted while the environment was being duplicated.
500Internal Server Error
server.error - an unexpected error; retry with backoff.
503Service Unavailable
