Contacts

Each agent keeps its own contact list. A contact has a name, an optional label (the purpose or relationship, such as dentist or landlord), and a phone number in E.164. Contacts belong to one agent: other agents on the same account cannot see them. Agents save and look up contacts through the API or MCP. Account owners can add, edit, and delete them in the dashboard under Contacts.

The Python SDK does not have contacts methods yet. The examples use curl and fetch.

Save a contact

curl -s -X POST "https://api.agentline.cloud/v1/agents/$AGENT_ID/contacts" \
  -H "Authorization: Bearer al_live_..." \
  -H "Content-Type: application/json" \
  -d '{"name": "Dr. Patel", "label": "dentist", "phone_number": "+12125557890"}'

const contact = await fetch(`https://api.agentline.cloud/v1/agents/${agentId}/contacts`, {
  method: "POST",
  headers: {
    Authorization: "Bearer al_live_...",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    name: "Dr. Patel",
    label: "dentist",
    phone_number: "+12125557890",
  }),
}).then((res) => res.json());

Field	Rule
`name`	Required. Up to 120 characters.
`phone_number`	Required. E.164 with the country code. Spaces, dashes, and parentheses are stripped.
`label`	Optional. Up to 64 characters. The purpose or relationship: `dentist`, `landlord`, `customer`.

The response is the contact, with an ID like con_.... A number can be saved once per agent. Saving it again returns 409 with the existing contact_id in detail, so update that contact instead. Two agents can each save the same number.

Find contacts

GET /v1/agents/{agent_id}/contacts returns contacts, total, limit, and offset, sorted by name.

Query	Matches
`q`	Substring of the name, label, or number. Case-insensitive.
`label`	Exact label, case-insensitive.
`phone_number`	One E.164 number. Use it to identify an inbound caller.
`limit`, `offset`	Paging. `limit` is 1 to 500, default 100.

curl -s "https://api.agentline.cloud/v1/agents/$AGENT_ID/contacts?label=dentist" \
  -H "Authorization: Bearer al_live_..."

const { contacts } = await fetch(
  `https://api.agentline.cloud/v1/agents/${agentId}/contacts?label=dentist`,
  { headers: { Authorization: "Bearer al_live_..." } },
).then((res) => res.json());

Update or delete a contact

PATCH changes only the fields you send. Send "label": null to clear the label.

curl -s -X PATCH "https://api.agentline.cloud/v1/agents/$AGENT_ID/contacts/$CONTACT_ID" \
  -H "Authorization: Bearer al_live_..." \
  -H "Content-Type: application/json" \
  -d '{"label": "orthodontist"}'

curl -s -X DELETE "https://api.agentline.cloud/v1/agents/$AGENT_ID/contacts/$CONTACT_ID" \
  -H "Authorization: Bearer al_live_..."

const headers = { Authorization: "Bearer al_live_..." };
const url = `https://api.agentline.cloud/v1/agents/${agentId}/contacts/${contactId}`;

await fetch(url, {
  method: "PATCH",
  headers: { ...headers, "Content-Type": "application/json" },
  body: JSON.stringify({ label: "orthodontist" }),
});
await fetch(url, { method: "DELETE", headers });
