Start an asynchronous deep research task on a question: Linkup searches the web and writes a sourced report. reasoningDepth S, M, L or XL sets depth and price. Read the result with linkup-research.

- **Tool id:** `linkup-research-post`
- **Provider:** [Linkup](/providers/linkup)
- **Job:** [Research web](/reference/jobs/web-research) (`web.research`)
- **Price:** $1.5 per call. A call that fails at the provider costs $0.

## Inputs

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `excludeDomains` | array | no | The domains you want to exclude of the search. By default, don't restrict the search. |
| `fromDate` | string | no | The date from which the search results should be considered, in ISO 8601 format (YYYY-MM-DD). It must be before `toDate`, if provided, and later than 1970-01-01. Example: "2025-01-01" |
| `includeDomains` | array | no | The domains you want to search on. By default, don't restrict the search. You can provide up to 100 domains. |
| `mode` | string | no | answer, auto (default), investigate or research. |
| `outputType` | string | yes | Output type: sourcedAnswer or structured. structured also needs structuredOutputSchema. Example: "sourcedAnswer" |
| `q` | string | yes | The natural language question for which you want to retrieve context. Example: "What is Microsoft's 2024 revenue?" |
| `reasoningDepth` | string | no | S, M, L or XL. Price: S $0.25, M $0.50, L $1.50 (default), XL $2.50. Example: "S" |
| `structuredOutputSchema` | string | no | Required only when `outputType` is `structured`. Provide a JSON schema (as a string) representing the desired response format. The root must be of type `object`. |
| `toDate` | string | no | The date until which the search results should be considered, in ISO 8601 format (YYYY-MM-DD). It must be later than `fromDate`, if provided, or than 1970-01-01. Example: "2025-06-30" |

## Output

The run's `result` holds the provider's answer. Signed in, `looot inspect linkup-research-post` prints its fields.

## Run it

Every call needs your API token in `LOOOT_TOKEN`; [Sign in](/get-started/sign-in#use-the-token-in-scripts-and-agents) shows how to get one. Each run also needs a new idempotency key, so a retry never pays twice. With `wait: 30` the answer comes back inline when the run ends within 30 seconds. Otherwise you get the running run back: poll `GET /v1/runs/<runId>`.
