List Holdings

The REST API is in beta. This endpoint’s response shape may change.

Returns a list of current holdings for a brokerage connection. Holdings are fetched live from the brokerage provider. No investment data is stored on Redbark servers.

This endpoint requires brokerage access. Trialing subscriptions on any plan receive full brokerage access. Outside a trial, brokerage access requires an active (or past_due) subscription on a Professional price. A key with no general API access (for example a Saver-plan key) gets a 403 with "code": "plan_upgrade_required". A Developer-plan key that has API access but not brokerage gets a 403 with "code": "professional_required" on this endpoint.

Request

GET /v1/holdings

Headers

Header	Required	Description
`Authorization`	Yes	`Bearer YOUR_API_KEY`

Trialing subscriptions on any plan receive full brokerage access, so you can evaluate /holdings and /trades during a trial. Outside a trial, brokerage access requires an active (or past_due) subscription on a Professional price.

Query parameters

Parameter	Type	Required	Description
`connectionId`	`string`	Yes	Brokerage connection to fetch holdings from
`accountId`	`string`	No	Filter to a specific brokerage account. Defaults to all accounts on the connection.
`accountIds`	`string`	No	Comma-separated subset of brokerage account UUIDs on the connection (max 4 000 chars). Takes precedence over `accountId` when both are passed. Any id not on the connection is a `404`.

connectionId must refer to a brokerage connection. Passing a banking connection ID returns a 400 error. Use the List Connections endpoint to find your brokerage connection IDs.

Response

Responses are not cached; every request fetches live from the brokerage provider.

Error responses

Errors use the standard envelope { "error": { "message": string, "code"?: string, "details"?: string[] } }. The optional code field is set for the structured cases below — clients should branch on code rather than parsing message.

Status	`code`	When
`400`	(none)	`Invalid request parameters` (missing `connectionId`; schema validation, offending fields in `details[]`)
`400`	`wrong_endpoint_for_category`	`Holdings are only available for brokerage connections` (passed a banking connection)
`403`	`plan_upgrade_required`	`Your plan does not include API access. The Redbark API and MCP server require the Developer or Professional plan (this is a plan limit, not a credentials issue)...` (keys with no API access, e.g. Saver plan)
`403`	`professional_required`	Developer-plan key hitting a brokerage endpoint
`404`	`connection_not_found` / `account_not_found`	Connection or account not found, or does not belong to you
`429`	(none)	Rate limit exceeded — heavy bucket is 30/min per API key, plus a per-key cap of 4 concurrent in-flight requests (excess returns `Too many concurrent requests`). See `Retry-After` and `X-RateLimit-Reset`.
`503`	(none)	Brokerage provider temporarily unavailable. Retry later.

Example error body:

{
  "error": {
    "message": "Brokerage endpoints require a Professional plan",
    "code": "professional_required"
  }
}
