Output

The run’s result holds the provider’s answer. Signed in, looot inspect hyperbrowser-api-task-browser-use 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>.

Example input with placeholder values:

curl -X POST "https://api.looot.ai/v1/runs" \
  -H "Authorization: Bearer $LOOOT_TOKEN" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $(uuidgen)" \
  -d '{"endpointId":"hyperbrowser-api-task-browser-use","input":{"task":"<task>","maxSteps":10},"wait":30}'

const response = await fetch("https://api.looot.ai/v1/runs", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.LOOOT_TOKEN}`,
    "Content-Type": "application/json",
    "Idempotency-Key": crypto.randomUUID(),
  },
  body: JSON.stringify({
    endpointId: "hyperbrowser-api-task-browser-use",
    input: {
      task: "<task>",
      maxSteps: 10,
    },
    wait: 30,
  }),
});
const run = await response.json();
console.log(run.status, run.result);
