  Balancer is a DeFi AMM and programmable liquidity platform supporting weighted, stable, and
  custom pools (v2 and v3). Balancer publishes a public GraphQL API at api-v3.balancer.fi for
  pool, swap, and analytics data, plus per-chain subgraph endpoints. Smart-contract entry
  points (Vault and Router) are the primary write surface; SDKs wrap the SOR (Smart Order
  Router) for client-side route construction.
