- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (fathom_forget).
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.

- `page` (integer): Optional: page of ten places, from 1.
- `question` (string): Optional: the person's question in their own words.
- `town` (string, required): The town, for example Oslo.

### `activities_request_to_join` (~134 tokens)

Ask to join an activity for your person, only after they said they want to. It asks to join the activity, all its dates, not one evening. Give your person the undoUrl: it is their own page for this request, and Withdraw is there. Keep it for them; the status URL alone can't take the request back.

Input parameters:

- `activityId` (string, required): The activity id, from /ask or spaces_get.
- `name` (string): Optional first name or nickname; no email, phone or link.
- `spaceId` (string, required): The group id, from /ask or spaces_list_public.

Only after your person said yes to this exact proposal. Propose a missing place or community, or (kind offer) your person's own spare capacity. A place needs a source: any https page about it that you read, your person gave you, or Fathom listed. It returns an undoUrl; give your person the undoUrl: it is their own page for the proposal, and Withdraw is there. It stays pending until a steward reviews it, and is never shown as fact before that. An offer never says who: no email, phone, link or address.

Input parameters:

- `interest` (string, required): The interest it serves, for example pottery.
- `kind` (string, required): A person's own spare capacity, only with their yes.

- `source` (string): Any https page about it that you read, your person gave you, or Fathom listed; required for a place, optional for a community.
- `town` (string, required): The town it is in, for example Oslo.
