## How to buy

novu turns text into professional voice audio and sells it per package, with no account: phone-menu (IVR) audio for a business's phone system, and voiceovers for videos. You write the text with the customer, in their language (Spanish is most common), and novu produces the audio. Human docs: https://novu.isbry.com/agentes.

Every order has the same five steps:
1) Call list_voices and share preview_url links so the customer picks a voice by ear.
2) Agree the exact text with the customer. novu reads it verbatim, so write numbers, emails and web addresses the way they should be spoken.
3) Create the package and tell the customer its price_cop, in Colombian pesos. Keep package_id: it is the only key to the package, and anyone holding it can download the audio, so share it only with the customer.
4) Call the pay tool with the customer's email. If they have a promo code, pass it and the package unlocks at once. Otherwise give them checkout_url, an ePayco payment page that lasts 24 hours; call the pay tool again if they lose it.
5) Call the get tool until status is ready (each call waits up to 20 seconds while generating), then give them download_url. It works for 7 days, and the get tool returns a fresh one on every call. novu produces the audio once paid even if this conversation ends, and emails the customer the download link.

IVR packages use create_ivr_package, pay_for_ivr_package and get_ivr_package. Write a greeting first, then a menu, one option per menu choice, plus after-hours and on-hold messages if they want them. Each message is one audio file of at most 700 characters. Price by message count: 1 message: individual, 54,000 COP; 2-3 messages: emprendedor, 132,000 COP; 4-5 messages: recepcion, 190,000 COP; 6-10 messages: pyme, 260,000 COP; 11-25 messages: empresa, 550,000 COP; 26-50 messages: call-center, 900,000 COP. Ask which phone system will play the audio and set audio_format: MP3 by default, pcm_16000 (WAV 16 kHz), or ulaw_8000 (common on Asterisk). Audio is usually ready 1 to 5 minutes after payment.

Video voiceovers use create_video_package, pay_for_video_package and get_video_package. One voice reads the whole script, delivered as MP3 and 48 kHz WAV. The script is at most 4,500 characters; put how it should sound in intent (at most 600 characters), never in the script. Price by script length: up to 1,000 characters: video-corto, 60,000 COP; 1,001-2,500 characters: video-medio, 120,000 COP; 2,501-4,500 characters: video-largo, 200,000 COP. There is no sample of the script before payment. Recording can take several minutes when other orders are ahead.

A failed call returns an error whose text starts with a code, such as rate_limited, and says what to do next. If a paid package fails, ask the customer to write to hola@novu.io with the package_id.
