API Reference

generate_podcast()

Generate a complete educational podcast.

generate_podcast(
    topic: str,           # Educational topic (e.g., "Dinosaurs")
    api_key: str,        # OpenAI API key
    output_file: str = "podcast.mp3",  # Output MP3 file path
    word_count: int = 700,              # Script length (700 ≈ 5 mins)
    languages: str = "en"               # Language code(s)
) -> str                 # Returns path to generated podcast

Example:

path = generate_podcast("Space Exploration", api_key, "my_podcast.mp3")
print(f"Podcast saved to: {path}")

create_script()

Generate just the podcast script (without audio).

create_script(
    api_key: str,
    topic: str,
    number_of_words: int = 500
) -> str

voice_over()

Convert script to audio with character voices.

voice_over(
    api_key: str,
    script: str,
    languages: str = "en"
) -> bytes

create_minibook()

Generate an educational mini-book in EPUB or PDF format.

create_minibook(
    api_key: str,                    # OpenAI API key
    topic: str,                      # Educational topic
    language: str = "en",            # Language code (e.g., "he", "es", "fr")
    number_of_words: int = 2000,     # Target word count
    output_format: str = "epub"      # Format: "epub" or "pdf"
) -> str                             # Returns path to generated file

Example:

# Generate Hebrew EPUB about FPV Drones
file_path = create_minibook(
    api_key=api_key,
    topic="FPV Drones",
    language="he",
    output_format="epub"
)
print(f"Mini-book saved to: {file_path}")  # fpv_drones_he.epub

script = create_script(api_key, "Ancient Rome", 600)

# Generate only Plato's audio
plato_audio = extract_character_audio(script, "Plato", api_key)

with open("plato_only.mp3", "wb") as f:
    f.write(plato_audio)

Workflow 3: Custom Language with Specific Word Count

from mindquest import generate_podcast

from mindquest import generate_podcast, create_minibook
import os

api_key = os.getenv("OPENAI_API_KEY")
topic = "The Water Cycle"
language = "es"  # Spanish

# Generate podcast for listening
podcast_path = generate_podcast(
    topic=topic,
    api_key=api_key,
    output_file="water_cycle_podcast.mp3",
    languages=language
)

# Generate mini-book for reading
ebook_path = create_minibook(
    api_key=api_key,
    topic=topic,
    language=language,
    output_format="epub"
)

print(f"Podcast: {podcast_path}")
print(f"E-Book: {ebook_path}")
