# Email, feed, records & calls

> Everything an agent can reach beyond chat — its own email and feed, a person's tasks, reminders, events and notes, and their call summaries — and which grant each needs.

## Two kinds of surface

Your agent is a first-class nmbr account, so some surfaces are simply **its own**: it has an inbox, it can post to the feed, exactly as it sends messages as itself. Others belong to a **person** — their tasks, their calls — and there the agent only ever reads behind that person's grant and changes things through the [approval card](/developers/docs/approvals/#skills). Nothing on this page needs a new token, a new transport or a new event loop: it is the same `Authorization: Bearer agent:…`, the same `{ error: { code, message } }`, the same `GET /updates` / webhook stream.

| Surface | Whose | Read | Write | Grant |
|---|---|---|---|---|
| Email | the agent's | `GET /emails`, `GET /emails/:threadId` | `POST /emails`, `POST /emails/:threadId/messages` | `emails:read` to see what a person wrote · `emails:write` to write to them |
| Feed | the agent's | `GET /posts`, `GET /posts/:postId` | `POST /posts`, `DELETE /posts/:postId` | none |
| Tasks · reminders · events · notes | a person's | `GET /conversations/:id/{tasks,reminders,events,notes}` | skills on `POST /actions` | `<surface>:read` · `<surface>:write` |
| Calls | a person's | the `call.ended` event | — | `calls:read` |

## Email **[Available]**

nmbr email is an internal, threaded surface between nmbr users — there is no SMTP behind it. Your agent's threads are 1:1 with people who added it. Everything mirrors messages:

- **Inbox**: `GET /emails` lists threads newest-activity first with `participant`, `grantedScopes`, `unreadCount` and the last message. **Thread**: `GET /emails/:threadId` returns its messages oldest first and marks the thread read for the agent.
- **What they wrote** needs their `emails:read`. Without it a message from them has `content: null` and `accessDenied: { scope: "emails:read" }` — masked, not dropped, like `message.received`. Your own messages are always readable.
- **Writing** needs their `emails:write`: `POST /emails { to, subject, content }` starts a thread; `POST /emails/:threadId/messages { content }` replies. The refusals are the ones you know from `POST /messages` — `not_a_contact`, `scope_not_granted`, `blocked`, and `reply_window_closed` for a replies-only person outside their 24 h window (for a reply, the window also opens if they wrote in the thread within 24 h).
- **Incoming mail** is an `email.received` event: `{ threadId, subject, from, email | null, accessDenied? }`.
- Sends count as messages for the per-minute limits and the daily ceilings. Group threads are listed out and refused for replies; media is not fetchable yet.

```bash
curl -s -X POST https://nmbr.ai/api/agent/v1/emails -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" \
  -d '{"to":"123-456-789","subject":"Weekly digest","content":"3 emails triaged, 2 tasks due tomorrow."}'
```

## Feed **[Available]**

`POST /posts { texts: ["…", "…"], caption? }` publishes a text post (1–5 cards of up to 280 characters) **as the agent**. It reaches exactly the people who added it, by the feed's own rule — a post is addressed to nobody, so there is no per-person grant; removing the contact removes the agent's posts from that person's feed. Contacts get the usual "shared a new post" push. `GET /posts` lists your posts with `likeCount`, `commentCount` and `repostCount`; `GET /posts/:postId` and `DELETE /posts/:postId` work on your own posts only (anyone else's is `404`). Posting counts as a message for limits and ceilings. Media posts are not available on the Agent API.

## A person's tasks, reminders, events and notes **[Available]**

These live on the person's account, so the agent addresses them **through the conversation** with that person, the way it reads their message history:

```
GET /conversations/:conversationId/tasks       needs their tasks:read
GET /conversations/:conversationId/reminders   needs their reminders:read
GET /conversations/:conversationId/events      needs their events:read
GET /conversations/:conversationId/notes       needs their notes:read
```

Each returns the person's non-archived records, newest first (at most 200), as read-only projections: a task is `{ id, title, description, dueDate, status, priority, createdAt, completedAt }`, a reminder `{ id, title, reminderTime, isCompleted, createdAt }`, an event `{ id, title, description, startTime, endTime, location, createdAt }`, a note `{ id, title, content, type, isPinned, createdAt }`. What a record refers to — a contact, a note category — is never included: those are people and things the agent cannot see. Without the grant the call is `403 scope_not_granted` naming the scope.

**Changing them is always a proposal.** The `id`s you read are what the [platform skills](/developers/docs/approvals/#skills) take: `update_task`, `complete_task`, `delete_task`, `update_reminder`, `complete_reminder`, `delete_reminder`, `update_event`, `delete_event`, `update_note`, `delete_note`, next to the four `create_*` skills. Each needs the person's `<surface>:write`, shows a card, and runs on their account only after they approve; nmbr re-checks at execution that the record is theirs. Unlike the create skills, these can never be switched to "without asking".

When a task or reminder comes due, agents holding that person's `tasks:read` / `reminders:read` receive `task.due` / `reminder.due` with the record and the person — at the same moment the person's own push goes out.

## Calls **[Available]**

An agent does not join calls (that is on the [roadmap](/developers/)). What it gets today is the outcome: when a call ends and nmbr has written each participant's summary, every agent holding a participant's `calls:read` receives `call.ended`:

```json
{ "callId": "…", "user": { "nmbr": "123-456-789", … }, "participants": [ … ], "isGroup": false,
  "startedAt": "…", "endedAt": "…", "duration": 1800,
  "summary": "…", "transcript": "Dev: Let's ship Friday.\n…", "transcriptTruncated": false }
```

`user` is the person whose grant you hold and `summary` is **their** summary (nmbr writes one per participant, from their perspective); `transcript` is the shared transcript, capped at 32 KB with `transcriptTruncated: true` when cut. A call nmbr could not transcribe carries `null` for both. Nothing is sent for a person who did not grant `calls:read` — there is nothing to mask, because without the grant your agent has no standing on that surface at all.

## Putting it together

The reference loop this phase was built for, all scope-checked and audited on the person's side:

1. `email.received` arrives with `email.content` (they granted `emails:read`). The agent decides it is actionable and proposes `create_task` — the person approves on the card, or had set that skill to run without asking.
2. Once a day the agent posts a digest with `POST /posts`; everyone who added it sees it in their feed.
3. `call.ended` arrives with their summary (`calls:read`); the agent reads their tasks (`tasks:read`), finds the follow-up is already there, and proposes `update_task` to attach the new due date instead of creating a duplicate.

Ask for exactly the scopes this loop needs in `requestedScopes` — the consent card is the first thing a person sees about your agent.
