COMPOSIO INSTANT

What is Composio Instant?

Composio Instant lets your agent use paid APIs like Elevenlabs without a separate account or API key for each one. New accounts start with $2 of free credit.

No Elevenlabs account or key

Your agent calls Elevenlabs through Composio, so there is nothing to sign up for, store, or rotate.

Pay per call, at cost

$0.08 per 1,000 Multilingual v2 input characters, paid from your Composio balance with zero markup.

Works in any agent

Claude, ChatGPT, Cursor, and other MCP clients, or your own code with the Composio SDK.

Works with your apps

Use Elevenlabs with Gmail, Slack, Google Sheets, and 1,700+ other apps you connect.

SDK

Use the Elevenlabs API in your code

Call Elevenlabs from your own agent with the Composio SDK. Four steps and one tool call.

1
Set up Composio
Turn on Instant Toolkits in your project settings and check your prepaid balance in Billing. Then set your API key.
export COMPOSIO_API_KEY="your_composio_api_key"
2
Install the SDK
The Python SDK needs Python 3.11 through 3.15.
The TypeScript SDK is ESM-only and needs Node.js 22.22.3 or newer.
pip install composio
npm install @composio/core
3
Run the call
Create a session that keeps Instant to this toolkit and reports the charge, then run the tool on the Instant account.
ELEVENLABS_TEXT_TO_SPEECH
4
Read the response
When the call runs on Instant, the response includes its charge: the amount as an exact USD decimal string, the currency and charged_by.

TROUBLESHOOTING

Elevenlabs API troubleshooting

Still stuck? The Instant tools docs cover limits, charges and session settings.

Set pronunciation_dictionary_locators in ELEVENLABS_TEXT_TO_SPEECH to apply a pronunciation dictionary.

In ELEVENLABS_COMPOSE_MUSIC, provide either prompt or composition_plan, since they cannot be combined.

Check its availability in the tools table. If it runs on Instant, check that Instant Toolkits is on for your project, your session allows the action and you use the latest toolkit version.

Your Composio balance is empty. Add funds in Billing if your plan supports it, or connect your own Elevenlabs account.

Check credential_source and instant_charge in the Composio execution log.
