Perplexity Integration

Route Perplexity API calls through SpendLil.

SpendLil proxies Perplexity's API. Swap api.perplexity.ai for perplexity.gateway.spendlil.ai and add X-SpendLil-Key. Perplexity is OpenAI-compatible — use the OpenAI SDK with the Perplexity gateway.

    api_key=os.environ['PERPLEXITY_API_KEY'],
    base_url='https://perplexity.gateway.spendlil.ai',
    default_headers={'X-SpendLil-Key': os.environ['SPENDLIL_KEY']},

cURL

bash Direct HTTP request

ℹ OpenAI-compatible

Perplexity's chat completions API mirrors OpenAI's schema, with additional fields for citations. Any OpenAI SDK or tool that accepts a base_url override will work unchanged.
