How this service works
ElevenLabs Flash Short Speech: Convert up to 500 characters to speech using ElevenLabs Flash v2.5 through BlockRun. Uses the Sarah voice and returns a hosted MP3 URL plus metadata. Text is sent to those providers. This is a short-speech offer with its stated character limit and model. 0.04 USDC includes up to 500 input characters.
Output
Returns a hosted MP3 URL pointing to the synthesized audio using ElevenLabs Flash v2.5 with the Sarah voice, along with metadata about the generated clip (e.g. character count, model used). The audio can be played or downloaded directly from the returned URL.
Example use cases
Automated notification voice message
“Turn this short alert into speech and give me an MP3 I can play: 'Your order has shipped and will arrive by Friday.'”
Podcast intro snippet generation
“Can you generate an audio clip of this intro line for my podcast episode? The text is: 'Hello and welcome back to Tech Mornings — I'm your host, and today we're diving deep into AI agents.'”
Accessibility audio for UI copy
“I need a spoken version of this button tooltip for accessibility purposes — please convert it to an MP3: 'Click here to save your progress and continue later.'”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-elevenlabs-short-speech?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need quick, low-latency text-to-speech for short messages (under 500 characters) and want a hosted MP3 URL back without managing your own ElevenLabs API keys. Ideal for agents that need to produce voice output on the fly, send audio notifications, or add accessibility narration to short UI text. Use an alternative for longer documents or when you need voice selection beyond the Sarah preset.
Side effects
- Text exceeds 500 character limit — request rejected
- Empty or missing text field — validation error
- ElevenLabs upstream service unavailable — synthesis fails
- Payment not fulfilled via x402 — request blocked
- Text contains unsupported characters — may produce unexpected audio output
