0x's Swap API is a go-to for token trading: aggregated liquidity across major DEXs plus RFQ market makers yields competitive quotes with clear route breakdowns. The endpoints are clean (/price, /quote), return ready-to-broadcast calldata, gas estimates, and slippage controls, which speeds integration. Multi-chain support (Ethereum, Polygon, BNB, Arbitrum, Optimism, Base, more) and solid uptime make it production-friendly. The docs and SDKs are strong, and affiliate/tracking params help monetize. Downsides: as an aggregator run by 0x Labs you depend on their infra and rate limits; coverage of brand-new pools/chains can lag, and quotes can expire or revert under high MEV/volatility unless you tune slippage or use private transactions. RFQ access may require whitelisting.
