Base Token Price via Uniswap V3GET /v1/base/token-price · x402 API by base-onchain-tools
USD price for ANY token on Base, not just the two assets Chainlink covers. Discovers every Uniswap V3 pool against WETH and USDC across all four fee tiers, reads sqrtPriceX96 and does the Q96 fixed-point maths, prices off the deepest pool, ignores deployed-but-never-traded pools whose prices are nonsense, and cross-checks the remaining ones to flag thin or manipulated liquidity. Query param: address.
