Prerequisites

Quickstart

Here’s an example of how to call and log AssemblyAI speech-to-text model with Keywords AI gateway. The API endpoint for this integration is https://api.keywordsai.co/api/assemblyai/.
Python
import os
from assemblyai import (
    Transcriber,
    Client,
    Settings,
    TranscriptStatus,
)
from base64 import b64encode
import json

API_KEY = os.getenv("KEYWORDSAI_API_KEY")
BASE_URL = (
    os.getenv("KEYWORDSAI_BASE_URL", "https://api.keywordsai.co/") + "api/assemblyai/"
)


class KeywordsAIAssemblyAIClient(Client):
    """
    Define KeywordsAI's AssemblyAI client wrapper for passing extra headers containing keywordsai params
    """

    def __init__(self, keywordsai_api_key: str, headers: dict):
        settings = Settings(api_key=keywordsai_api_key, base_url=BASE_URL)
        print(settings)
        super().__init__(settings=settings)
        self._http_client.headers.update(headers)

keywordsai_params = {
    "metadata": {
        "paid_user": "true",
    }
    # other keywordsai parameters...
}

keywordsai_headers = {
    "X-Assemblyai-Api-Key": os.getenv("ASSEMBLYAI_API_KEY"), # <-- This is the AssemblyAI API key
    "X-Data-Keywordsai-Params": b64encode(
        json.dumps(keywordsai_params).encode()
    ).decode(),
}

client = KeywordsAIAssemblyAIClient(
    keywordsai_api_key=API_KEY, # <-- This is the API key for authenticating against KeywordsAI, not the AssemblyAI API key (defined above)
    headers=keywordsai_headers
)

transcriber = Transcriber(client=client)

transcript = transcriber.transcribe("https://assembly.ai/wildfires.mp3")

if transcript.status == TranscriptStatus.error:
    print(transcript.error)
else:
    print(transcript.text)
