Personas

See People for what each field does.

GET /api/personas

Every persona in the universe, sorted by name.

POST /api/personas

Creates a persona. addresses needs at least one address, and an address can belong to only one persona. Anything you leave out gets a default: a temperament drawn at random, knows: "some", a mail client drawn at random.

curl -s -X POST https://c1.simmail.dev/api/personas \
  -H "Authorization: Bearer smk_your_key" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Dana Reyes",
    "addresses": ["[email protected]"],
    "role": "homeowner",
    "org": "",
    "who": "Retired teacher selling the family home on Clark Street",
    "wants": "a fair price and a quick, simple sale",
    "temperament": "skeptical",
    "style": { "length": "short", "formality": "neutral", "signature": "Dana", "client": "iphone", "links": "wary" },
    "timing": {
      "reply_rate": 0.9,
      "delay": { "median": "2h", "spread": 1.8 },
      "hours": { "tz": "America/Chicago", "days": "mon-fri", "from": "09:00", "to": "17:00" },
      "ooo": [{ "from": "2026-12-20", "to": "2027-01-02", "message": "Away for the holidays." }]
    },
    "behaviors": { "double_reply": 0.1, "keep_promises": 0.5 },
    "external_ids": { "crm": "c-1042" }
  }'

The answer is the saved persona, with its new id (such as p_3fa2b1c9d0), provider (api) and created. Creating one also makes its mailbox.

provider says where a persona came from: api, case, stranger, world, mail or config (a YAML file).

GET /api/personas/{id}

One persona. 404 if there is none.

PATCH /api/personas/{id}

Changes only the fields you send. PUT does the same.

curl -s -X PATCH https://c1.simmail.dev/api/personas/p_3fa2b1c9d0 \
  -H "Authorization: Bearer smk_your_key" \
  -H "Content-Type: application/json" \
  -d '{"paused": true}'

A nested object you send replaces that whole object: sending {"style": {"links": "never"}} clears the person’s other style settings. Read the persona first and send the whole style, timing or behaviors object.

Personas from YAML files cannot be changed through the API (409).

DELETE /api/personas/{id}

Deletes the persona with its memory, relations and pending jobs. Its mailbox and mail are kept.

POST /api/personas/from-mail

Learns a persona from an address’s mail in this universe. See Learning a person from mail.

{ "address": "[email protected]", "paused": false }

Answer: {"persona": {…}, "by": "ai", "people": 4}, where people is how many correspondents they already know. Counts toward your plan’s monthly “learned from mail” allowance.

GET /api/temperaments

The temperaments, with name, weight (odds when drawn), reply_rate, median_delay and text.
