# Gumroad Call Slots API

Open availability on a Gumroad call product, as ISO start and end times.

`GET /v1/gumroad/product/call-slots` takes the same product target as the product route: a product `url`, or `creator` plus `permalink`, or a bare `permalink`. It answers `{ data, meta }` with `data.lookupStatus`, `data.creator`, `data.permalink` and `data.slots`.

Each slot has `start` and `end` as ISO 8601 times. `slots` is the creator's open availability, and it can be empty when every slot is taken. You can pass the slug from the product URL; the answer echoes the product's `permalink`. An existing product that is not a call answers `found` with an empty `slots` list. Only an unknown or deleted product answers `not_found`. The route does not page: call slots are a bounded availability list for one product.

## FAQ

### How do I name the call product?

Give the product URL, or the permalink plus the creator storefront when the product lives on a creator host. A custom permalink copied from the product URL is accepted; the answer echoes the product's `permalink`.

### What is in each slot?

Each slot has start and end, both ISO 8601 timestamps. Sort or filter them in your own code; the array is the creator's open availability.

### What does a product that is not a call return?

An existing digital product, membership or commission returns found with an empty slots list. Only an unknown or deleted product returns not_found, so use the product route's type when you need to tell a non-call product from a call product with every slot taken.

### Can slots be empty on a found product?

Yes. A call product with no open availability answers found with an empty slots array. Check slots.length rather than lookupStatus alone when you need a bookable time.

### How many credits does a call-slots request cost?

Pricing is documented on the operation in the API registry (shown on this page). Confirm on every response with meta.creditsCharged: that field is the billing source of truth.
