Get a sign-up page

GET /api/v1/signup-pages/{id} One sign-up page, with its content — this is the call that gives you the HTML the list does not carry.

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
`id`	string	Required. The page to read

Example

bash

curl -H "x-api-key: $AGENTMAIL_API_KEY" \
  "https://www.agentsmail.io/api/v1/signup-pages/$SIGNUP_PAGE_ID"

Response

200 OK — the page and its HTML.
401 Unauthorized — missing or invalid key, or its owner left the organization.
404 Not Found — no such page, 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 — the key is over its rate limit.

Notes

The organization is never in the answer. It is the one your key opens, and you already know it.
A draft page answers 200 here even though its public address answers a not-found page. The two are different questions.
