List selectable signature methods
Returns the signature methods you can offer a signer, with display labels — the generic methods plus every currently-available eID scheme.
This is the pickable set, not every accepted value. NONE and MANUAL are still accepted on signatureMethod but are omitted here because the app derives them rather than offering them: NONE is what a party gets when its role isn’t a signing role, and MANUAL is for an imported archive document that was already signed on paper.
Build signature-method pickers from this rather than hard-coding the list: eID schemes are switched on per market over time, and sending a scheme that isn’t available yet is rejected with “This eID scheme is not yet available”.

Authorizations
Personal API key, e.g. Authorization: Bearer sajn_sk_.... Not scope-limited — acts as the issuing user.
Headers
API version for this request. Without it, the request uses the organization's default version; an organization without a default is pinned to the latest version by its first request.
2026-09, 2026-10 ID of the workspace this request acts in, from GET /api/v1/workspaces. Without it, an API key acts in its default workspace. The token's user must be a member of the workspace; an OAuth token only accepts the workspace it was granted for. A workspace that doesn't exist or can't be reached returns 403 WORKSPACE_ACCESS_DENIED.
