How this service works
Raw AMM pool state for a pair on Base: v2 reserves and v3 concentrated liquidity across BaseSwap, SushiSwap and Uniswap v3. Returns pools[] with venue, surface, feeBps, reserveA, reserveB, price and tvlUsd at a stated blockNumber. Requires ?pair=SYM/SYM (e.g. WETH/USDC). Errors: 400 bad_pair, 404 no_pools, 502 upstream_read_failed. For USD depth already computed use /liquidity. This is the underlying numbers. Chain-pinned; bare /reserves = BSC.
Output
Returns per-venue pool data for the requested trading pair on Base, including: both token reserves (raw onchain amounts), pool mid price, fee tier in basis points, and USD TVL — scoped to a specific block — for each of BaseSwap, SushiSwap, and Uniswap v3 pools where the pair exists.
Example use cases
Pre-trade slippage estimation on Base
“Before I swap 50 ETH for USDC on Base, can you get me the current pool reserves and mid price across BaseSwap, SushiSwap, and Uniswap v3 so I can estimate my slippage?”
Cross-venue arbitrage math on Base
“I think there's an arbitrage opportunity between BaseSwap and Uniswap v3 for the WETH/USDC pair on Base — can you pull the raw pool reserves and fee tiers for both venues right now so I can do the math?”
TVL and liquidity snapshot for DeFi dashboard
“Get me the current TVL and pool state for the USDC/DAI pair on all supported DEXs on Base, including fee tiers and both reserve amounts, so I can update my liquidity dashboard.”
Technical details
Endpoint
GEThttps://x402.donnyautomation.com/base/reservesWhen to prefer
Use this endpoint when you need raw on-chain AMM pool state on Base L2 specifically — reserves, mid price, fee tier, and TVL across BaseSwap, SushiSwap, and Uniswap v3 — to power your own quote math, price impact calculations, slippage models, or arbitrage detection. Prefer this over higher-level quote endpoints when you need the underlying numbers rather than a pre-computed best execution price.
Side effects
- Invalid or unrecognized token pair symbol returns an error or empty result
- Pair not listed on any supported Base DEX returns no pool data
- Network or RPC node issues on Base L2 may cause timeouts
- Stale block data if the chain is experiencing congestion
- Payment failure (402) if USDC payment is not included or insufficient
