How this service works
Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.
Output
A JSON object containing the base64-encoded MP3 audio string (audio_base64), the total byte size of the audio (bytes), the number of characters processed (chars), and the format identifier ('mp3'). The base64 string can be decoded to produce a playable MP3 file.
Example use cases
Spoken notification for trading alert
“Convert this trading alert into spoken audio so I can play it: 'BTC just crossed your target price of 70,000 dollars. Consider reviewing your position.'”
Multilingual customer message narration
“Turn this customer update into Spanish audio I can embed in my app: 'Su pedido ha sido enviado y llegará en dos días.'”
AI agent voice announcement
“Generate an MP3 of this announcement being spoken in French: 'Le marché est maintenant ouvert. Bonne chance à tous les traders.'”
