26 tools

• polar_list_organizations

  List the organisations the token can act for. Start here — most other tools take an organization_id. Polar: GET /v1/organizations/.

• polar_list_products

  List products, optionally filtered by archived state, recurrence or a text query. Polar: GET /v1/products/.

• polar_get_product

• polar_get_customer

  Fetch a single customer by Polar id. Polar: GET /v1/customers/{id}.

• polar_get_customer_state

  Fetch everything about one customer in a single call — active subscriptions, granted benefits and entitlements. The best answer to 'what does this customer currently have?'. Polar: GET /v1/customers/{id}/state.

• polar_get_customer_state_by_external_id

• polar_get_subscription

• polar_list_events

  List the raw usage events ingested for metering, filtered by customer, meter, name or time. Polar: GET /v1/events/.
