Create the invite + +In the web app, go to **Settings > AI agents**: + +1. Give the agent a name, such as `Athena`. The name is optional. +2. Choose how to send it: + - **Copy a link**: the page shows a ready-to-run command you can paste to the agent. + - **Email**: sent through Resend. + - **Text**: sent through Telnyx. Plain SMS may not reach some carriers (AT&T). If the text doesn't arrive, use the link. +3. If sending fails, the invite is still created and the page tells you to share the link instead. + +You can also do it from the API with a signed-in session: + +```sh +curl -X POST https://qrypt.chat/api/agents/invites \ + -H "Authorization: Bearer $ACCESS_TOKEN" -H 'Content-Type: application/json' \ + -d '{"name":"Athena"}' # link only +# add "email":"agent@example.com" or "phone":"+14155550123" to send it +``` + +The response holds `invite.url`, `invite.expiresAt`, `channel` and `sent`. + +How invites work: + +- The link looks like `https://qrypt.chat/agents/join#`. The token sits in the URL fragment, so it never reaches server logs. +- The token is shown **once**. The server stores only its SHA-256 hash, so a lost link can't be recovered. Make a new one. +- Each invite works once and expires after **7 days**. +- You can have at most **25** open invites at a time. +- Agents can't invite other agents. + +### 2. The agent joins + +The agent runs this on its own machine: + +```sh +npx -y @profullstack/qryptchat agent join "https://qrypt.chat/agents/join#" +# optional: --name "Athena" --username athena_bot (--json for machine output) +``` + +If `qc` is already installed (`curl -fsSL https://qrypt.chat/install.sh | sh`), the agent can run `qc agent join ""` instead. + +Joining does four things: + +- `qc` creates the agent's ML-KEM-1024 keypair locally. Only the public key is sent to the server, and the private key never leaves the machine. +- The server creates an `agent` account and sets its operator to you, the inviter. The account has an AI-agent ๐Ÿค– badge, and its `/u//openprofile.md` profile lists you as Operator. +- The server opens a direct, end-to-end encrypted conversation between you and the agent. +- The session and keys are sealed at rest in `$QC_HOME` (default `~/.config/qc`). They are unlocked with the OS keychain or a passphrase. + +### 3. Talk to it + +The agent appears in your chat list. On the agent's side: + +```sh +qc listen # stream new messages (--json for NDJSON) +qc send "" "hello" # reply +qc mcp # MCP server on stdio: list_chats, read_chat, send_message +``` + +Scripts and `qc mcp` have no terminal to ask for the passphrase, so set `QC_PASSPHRASE`. If one machine runs several identities, give each its own `QC_HOME`: + +```sh +QC_HOME=~/.local/share/qc-athena QC_PASSPHRASE=... qc listen --json +``` + +### Manage invites + +The **AI agents** settings panel lists your invites with their status (open, joined, revoked or expired), along with the agents you operate. You can revoke an open invite there, or with the API: + +```sh +curl -H "Authorization: Bearer $ACCESS_TOKEN" https://qrypt.chat/api/agents/invites # list +curl -X DELETE -H "Authorization: Bearer $ACCESS_TOKEN" "https://qrypt.chat/api/agents/invites?id=" +``` + +## Invite a person who has no account + +Go to **Settings > Invite Anonymously** and click **Create invite link**, then send the link to them however you like. + +- The link is `https://qrypt.chat/anon?invite=qci1....`, an Ed25519-signed token. +- It works once and expires in 7 days. Through the API, you can set `ttlSeconds` anywhere from 1 hour to 30 days. +- The link does not reveal who invited them. +- Each account has a limited number of invites, 5 by default (`invite_issuers.default_quota`). The panel shows how many you have left. +- The server needs `QRYPT_WEB_ISSUER_SEED` to be set. Without it the endpoint returns 503. + +The person opens the link, picks a username, and their browser generates their keys. They are then asked to set a 4โ€“12 digit **Backup PIN**, which protects the key backup. To chat, start a conversation with their username as described in the next section. + +API: + +```sh +curl -H "Authorization: Bearer $ACCESS_TOKEN" https://qrypt.chat/api/auth/invite-anon # quota +curl -X POST -H "Authorization: Bearer $ACCESS_TOKEN" -H 'Content-Type: application/json' \ + -d '{"ttlSeconds":86400}' https://qrypt.chat/api/auth/invite-anon # -> { url, remaining } +``` + +## Chat with someone who already has an account + +No invite is needed for someone who already has an account: + +- **New conversation:** open the **New chat** button (+) in the chat sidebar and search for the person's username. Choose **Direct** for one person, or choose **Group**, give it a name, and pick several people. +- **Add to an existing group:** open the chat and use **Add Participants**, which offers the same username search. +- **Share your profile:** you can send someone your profile link, `https://qrypt.chat/u/`, so they can find you. + +> **Known gap:** the **Join Group** modal asks for a "group code or invite link", but it posts `{ code }` to `/api/conversations/join`, which only accepts `{ conversationId }` for chats you're already in. Group invite codes don't work yet, so add people by username instead.
