}Set the base currency
Promotes this currency to the entity’s base currency and demotes the previous base currency in the same transaction, so exactly one base currency exists at a time. Requires currencies:write scope.

}Authorizations
API key issued per entity via Settings > Developers > API Keys.
Each key carries scopes (e.g. orders:read, products:write).
Bearer token format: Authorization: Bearer ark_live_ent_Test keys use ark_test_ent_. Both are issued per entity
via Settings > Developers > API Keys.
Path Parameters
Response
Promoted currency
A currency that the entity transacts in. USD is seeded on entity creation with is_base=true. Wave B multi-currency foundation: exchange_rates link non-base currencies to the base. Soft-delete refuses with HTTP 409 if the row is the entity's base currency; promote a different currency first via POST /currencies/{id}/set-base. Scope: currencies:read / currencies:write / currencies:delete. Rule 23 SSOT: is_base is flipped only by canonical setBaseCurrency (atomically demotes the previous base in the same transaction).
"currency"
ISO 4217 currency code, UPPERCASE 3 letters.
3"USD"
Human-readable currency name. 1..80 chars.
Display symbol. Optional; up to 8 chars.
Display precision. JPY = 0, BHD = 3, most = 2.
True for exactly one currency per entity. Read-only; set via set-base.
Free-form caller metadata. Default {}.
