Get one list

GET /api/v1/lists/{listId} One list.

bash

curl -H "x-api-key: $AGENTMAIL_API_KEY" \
  "https://www.agentsmail.io/api/v1/lists/$LIST_ID"

The detail carries no contactCount: the count is computed only when listing. A list that does not exist and a list belonging to another organization both answer 404 — the API never tells you an id exists when it is not yours.

Authorization

Role in the organization	This endpoint
`OWNER`	Allowed
`ADMIN`	Allowed
`MEMBER`	Allowed

A key carries the role its creator holds in this organization — never a role on AgentsMail itself. See API keys.

Path parameters

Parameter	Type	Description
`listId`	string	Required. The list to read

Example

bash

curl -H "x-api-key: $AGENTMAIL_API_KEY" \
  "https://www.agentsmail.io/api/v1/lists/$LIST_ID"

Response

200 OK — the call succeeded.
401 Unauthorized — missing or invalid key, or its owner left the organization.
404 Not Found — no such resource, or it belongs to another organization. The API never confirms that an id exists to a caller who has no right to it.
429 Too Many Requests — over 120 requests in a minute for this key.
