KeyPool

KeyPool is an API key pooling proxy running on Cloudflare Workers. It aggregates multiple upstream API keys per service (Exa, Firecrawl, AssemblyAI, Groq, Tavily, Serper, ElevenLabs, Cartesia, Deepgram), load-balances across them, and exposes a single team-facing endpoint with unified auth, rate limiting, and usage tracking.

Authentication

Use your KeyPool team token as one of:

• Authorization: Bearer <team-token> (preferred)

• xi-api-key: <team-token> (for ElevenLabs compatibility)

KeyPool will inject the real upstream key according to the target service’s auth scheme.
