Output

Shape of the run’s result, the expected shape, not yet checked against real answers:

{ media: { mediaId, contentType, byteLength, sha256, expiresAt, downloadPath } }

Run it

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":"job:audio.speech.generate","input":{"text":"<text>"},"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: "job:audio.speech.generate",
    input: {
      text: "<text>",
    },
    wait: 30,
  }),
});
const run = await response.json();
console.log(run.status, run.result);

import requests

response = requests.post(
    "https://api.looot.ai/v1/runs",

        "Idempotency-Key": str(uuid.uuid4()),

            "text": "<text>",
        },
        "wait": 30,
    },
    timeout=90,
)
run = response.json()
print(run["status"], run.get("result"))

To pin one provider, send its tool id as endpointId instead of job:audio.speech.generate.
