ContentFlow Python SDK

Podcast intelligence API — transcripts, semantic search, entity extraction, topic classification, and AI summaries from 50,000+ hours of business podcasts.

Installation

pip install contentflow-sdk

Quick Start

from contentflow import ContentFlow

client = ContentFlow(api_key="pk_live_...")

# Search 50,000+ hours of podcast content
results = client.search.hybrid(query="AI fundraising strategies")
for result in results.results:
    print(f"{result.title}: {result.best_chunk_text[:100]}")

# Transcribe any YouTube video
job = client.jobs.create(youtube_url="https://youtube.com/watch?v=...")
job = client.jobs.wait(job.id)  # polls until complete

summary = client.jobs.get_summary(job.id)
print(summary.summaries[0].content)

Async Support

from contentflow import AsyncContentFlow

async with AsyncContentFlow() as client:
    job = await client.jobs.create(youtube_url="https://youtube.com/watch?v=...")
    job = await client.jobs.wait(job.id)
    transcript = await client.jobs.get_transcript(job.id)

Features

• Typed responses — full Pydantic models with IDE autocomplete
• Sync + async — ContentFlow and AsyncContentFlow clients
• Smart polling — jobs.wait() with exponential backoff
• Automatic retries — configurable retry with backoff on transient errors
• Rate limit handling — parsed rate limit headers on RateLimitError
• CLI tool — pip install contentflow-sdk[cli] for terminal access
