# ElevenLabs Sound Effects v2 text to sound effect

Needs text. Served by fal.ai.

ElevenLabs Sound Effects v2, text to sound effect, served by fal.ai. The OpenAPI schema for the fal-ai/elevenlabs/sound-effects/v2 queue. Price: $0.002 per second of audio; without duration_seconds the model picks a length up to 22 s, billed as 22 s. Waits up to 40 s for the result; if the generation takes longer, the run stays RUNNING and returns a request_id; poll fal/status and fetch fal/result with model "fal-ai/elevenlabs" and that request_id.

## Published example

This is the provider tool’s published example. Replace example values with the user’s requested inputs, respecting the schema; do not execute an example merely to test a connection.


```json
{

  "input": {
    "text": "a single soft door knock",
    "duration_seconds": 1
  }

## Execute and retrieve

Inspect again before execution, explain the price and obtain the required authority. Use MCP run_tool or POST /v1/run with this tool ID, valid input and an idempotency key. Save the returned run ID and follow the actual state. If Agentik answers that the tool is temporarily unavailable, do not retry it blindly; use discovery to propose an alternative.

This tool uses deferred settlement. Follow its returned task/run instructions; preserve the existing reservation until the result is reconciled.

A partial or uncertain result can still have consumed provider resources. Consult [billing](/docs/billing.md), [idempotency](/docs/idempotency.md) and [asynchronous results](/docs/async.md).
