# Lovable, v0 and Base44

> Setup guides for building Opencals booking sites in Lovable (custom connector), v0 (agent skills) and Base44 (backend function + workspace skills).

**September 26, 2026**

## Build booking sites in Lovable, v0 and Base44

Three new guides in the renamed **[AI & Builders](/docs/ai-agents/overview.md)** tab, each
with every field and file ready to copy:

* **[Lovable](/docs/ai-agents/lovable.md)**: add Opencals as a custom connector with
  Advanced auth (`X-Api-Key` + `X-Api-Version`) and two knowledge files.
* **[v0](/docs/ai-agents/v0.md)**: attach `letsopencals/skills` from skills.sh and set
  `OPENCALS_API_KEY`.
* **[Base44](/docs/ai-agents/base44.md)**: an `opencals` backend function, an app secret
  and two workspace skills.

The knowledge files are also published as plain Markdown at
[opencals.com/ai/opencals-storefront-api.md](https://opencals.com/ai/opencals-storefront-api.md),
[lovable-booking-site-playbook.md](https://opencals.com/ai/lovable-booking-site-playbook.md) and
[base44-booking-site-playbook.md](https://opencals.com/ai/base44-booking-site-playbook.md).
