GET `/api/v1/models/{id}`

One model with targets.

Scope reference:read
ETag
operationId portfolioModel

The token needs the scope reference:read, and the person or service account behind it needs the matching privileges and account permissions, exactly as on the screens. See Scopes.

ETag. The answer carries an ETag header. Keep it: changing this resource needs If-Match with that value.

Status codes and errors

Errors are application/problem+json (RFC 9457) with a stable code to program against; the detail says what to fix. See Errors.

Status	When	Problem codes
200	Success
400	The request is malformed	`invalid_request`
401	No token, or it is invalid or expired	`invalid_token`
403	The token lacks the scope, or the person or service account behind it lacks the privilege or account permission	`insufficient_scope` `forbidden` `ip_not_allowed`
404	Not found, or not visible to you (the API never confirms what you may not see)	`not_found`
429	Rate limited: wait for Retry-After seconds	`rate_limited`
