Create an asynchronous Agent run. By default, the API returns the run object immediately. Set `Accept: text/event-stream` to stream run lifecycle events until the run reaches a terminal status.

- **Tool id:** `exa-agent-runs-post`
- **Provider:** [Exa](/providers/exa)
- **Job:** [Create agent runs](/reference/jobs/agent-runs-create) (`agent.runs.create`)
- **Price:** $0.15 per call. A call that fails at the provider costs $0.

## Inputs

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `budget` | string | no | Optional per-run spending limit for the metered `auto` and `max` efforts. Runs that finish early may cost less than the limit. |
| `dataSources` | array | no | Exa Connect data providers to enable for the run. Each entry enables all of that provider's tools. |
| `effort` | string | no | Cost and reasoning effort preference for the run. `auto` lets Exa choose the appropriate effort. `max` is the highest-effort public beta tier for work where completeness and thoroughness matter more than latency or cost, including large list building, deep multi-source research, and criteria that are hard to verify. |
| `input` | string | no | Records to process and records or entities to exclude from the answer. |
| `metadata` | string | no | Caller-provided metadata stored with the run. |
| `outputSchema` | string | no |   |
| `previousRunId` | string | no | Agent run ID. New run IDs are returned with the `agent_run_` prefix. |
| `query` | string | yes | Natural-language question or instructions for the request. |
| `systemPrompt` | string | no | Additional instructions that guide generated output or agent behavior. Use this for source preferences, novelty constraints, duplication constraints, or other behavior guidance. Example: "Prefer official sources and avoid duplicate results." |

## Output

The run's `result` holds the provider's answer. Signed in, `looot inspect exa-agent-runs-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>`.

To let looot pick among every provider of this job instead, send `job:agent.runs.create` as `endpointId`; see [the job page](/reference/jobs/agent-runs-create).
