Tools (26)

`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`	Fetch a single product with its prices and attached benefits. Polar: GET /v1/products/{id}.

`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`	Same as polar_get_customer_state, but looked up by YOUR external id rather than Polar's — the usual path when you hold your own user id. Polar: GET /v1/customers/external/{external_id}/state.

`polar_get_subscription`	Fetch a single subscription with its product, price and period. Polar: GET /v1/subscriptions/{id}.
`polar_get_metrics`	Fetch revenue and subscription metrics over a date range, bucketed by interval — orders, revenue, MRR, active subscriptions. Polar: GET /v1/metrics/.
`polar_list_benefits`	List benefits — the things a product grants, such as licence keys, file downloads or Discord roles. Polar: GET /v1/benefits/.
`polar_list_benefit_grants`	List who has been granted one benefit, and whether the grant is still active. Polar: GET /v1/benefits/{id}/grants.

`polar_list_meters`	List the usage meters that aggregate events into billable quantities. Polar: GET /v1/meters/.
`polar_get_meter_quantities`	Fetch the aggregated quantities a meter has recorded over a window — what usage-based billing will charge for. Polar: GET /v1/meters/{id}/quantities.
`polar_list_events`	List the raw usage events ingested for metering, filtered by customer, meter, name or time. Polar: GET /v1/events/.
`polar_list_webhook_deliveries`	List webhook delivery attempts with their HTTP results — the tool for 'why did my webhook not arrive?'. Polar: GET /v1/webhooks/deliveries.
`polar_list_webhook_endpoints`	List the configured webhook endpoints and their subscribed events. Polar: GET /v1/webhooks/endpoints.
`polar_redeliver_webhook_event`	Queue one webhook event for redelivery after your endpoint recovered. Polar: POST /v1/webhooks/events/{id}/redeliver.
`polar_create_refund`	Refund an order, in full or in part. This moves real money back to the customer. Polar: POST /v1/refunds/.
`polar_cancel_subscription`	Cancel a subscription at the end of its current period. The customer keeps access until then. Polar: PATCH /v1/subscriptions/{id}.
`polar_create_checkout_link`	Create a reusable checkout URL for one or more products — the link you put in a page or an email. Polar: POST /v1/checkout-links/.
