"""
Unified API Key Registry - Multi-Key Pools with Load Balancing

Discovers all API keys from environment variables and groups them
by provider into key pools. Each pool handles:
  - Round-robin key rotation
  - Per-key rate limiting (token bucket)
  - Per-key monthly quota tracking
  - Automatic fallback on 429/401
  - Health scoring (success rate, latency)

Providers managed:
  HELIUS (3 keys)     - Solana RPC
  QUICKNODE (1 key)   - Solana RPC
  ALCHEMY (1 key)     - Solana RPC
  SOLANA_TRACKER (2)  - Indexed Solana data
  BIRDEYE (1 key)     - Token analytics
  SOLSCAN (1 key)     - Block explorer API
  MORALIS (3 keys)    - EVM wallet data
  ETHERSCAN (1 key)   - EVM explorer
  COINGECKO (1 key)   - Price data
  THEGRAPH (1 key)    - Subgraph queries
  GOPLUS (1 key)      - Token security
  NANSEN (1 key)      - Wallet labels
  DUNE (1 key)        - Analytics
  ARKHAM (1 key)      - Entity intelligence
  LUNARCRUSH (1 key)  - Social signals
