Exa Public API / Create a run

Exa tool exa-agent-runs-post on looot: input fields, $0.15 per call, output shape, and code to run it with curl, JavaScript or Python.

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
Job: Create agent runs (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.

Every call needs your API token in LOOOT_TOKEN; Sign in 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>.
