# Every field type, its settings and its limits

`GET https://studio.gtable.app/v1/field-types`

The catalogue: each type's id, label, which group it belongs to in the picker, whether it is stored, computed or a relation, whether anybody may write to it, its character or magnitude limit, and the shape of its `config`.

Read it before inventing a setting, a config key that does not belong to the type is a validation error, not something quietly ignored.

Requires the `schema:read` scope. Operation `fields.types`. MCP tool `fields_types`. CLI, once published: `gtable fields types`.
