# Call the getAccountCapacity MCP tool

`POST /api/v1/actions/getAccountCapacity`

## Request

- Base URL: `https://app.reachium.io`
- URL: `https://app.reachium.io/api/v1/actions/getAccountCapacity`
- Auth: HTTP bearer

Get today’s remaining sending headroom for every LinkedIn account in the workspace: invites and messages used vs their limit, as a percentage with a tone. tone: ok (<90%), warn (90-99%), full (>=100%), blocked (limit set to 0). limit_source "default" means no custom limit row exists so the platform defaults apply (25 invites / 50 messages); over_limit flags usage past the ceiling. Use before scheduling more outreach to see which accounts are near their daily ceiling.

Called through the Actions bridge: the response is that tool's own result, wrapped as `{ data: <tool result> }` under HTTP 200. Billing, daily-cap, and confirm-step outcomes are embedded INSIDE `data`, never remapped to an HTTP status (see the templated `/api/v1/actions/{toolName}` operation above for the full protocol, and `x-mcp-actions` for this tool's machine-readable scope/cap/confirm_behavior fields). Authentication, request-shape, and optional idempotency-protocol failures still use their documented non-200 statuses.

## Headers

- `Idempotency-Key` string

## Request body

- object

## Response `200`

The result of calling this tool.

- object
  - `data` unknown, required
  - `error` unknown, required

## Other responses

- `400`: The request body was not a JSON object (code invalid_request), or Idempotency-Key is malformed (code invalid_idempotency_key).
- `401`: Missing or invalid API key. Send `Authorization: Bearer rmcp_...` (code unauthorized).
- `403`: This tool is out of the key’s granted scope (code insufficient_scope).
- `409`: This Idempotency-Key has an unresolved in-flight or ambiguous result (code request_in_flight). Reconcile before using a new key.
- `422`: This Idempotency-Key was already used with a different request body (code idempotency_key_reuse).
- `429`: Rate limited: shared `mcp:ip:{ip}` (600/60s) or `mcp:key:{keyId}` (120/60s) bucket, the SAME buckets the MCP endpoint uses (code rate_limited).
- `500`: Unhandled server error (code internal_error).
