How this service works
Raw AMM pool state for a pair on BSC / BNB Chain: v2 reserves and v3 concentrated liquidity across PancakeSwap v2/v3, Biswap, ApeSwap. Returns pools[] with venue, surface, feeBps, reserveA, reserveB, price and tvlUsd at a stated blockNumber. Requires ?pair=SYM/SYM (e.g. WBNB/USDT). Errors: 400 bad_pair, 404 no_pools, 502 upstream_read_failed. For USD depth already computed use /liquidity. This is the underlying numbers. Bare = BSC; also /polygon /arbitrum /avalanche /optimism /base.
Output
Returns per-venue pool data for the requested trading pair on BSC/BNB Chain, including: raw token reserves for both sides, pool mid price, fee tier in basis points, USD TVL, and the block at which the data was captured — covering PancakeSwap v2, PancakeSwap v3, Biswap, and ApeSwap where the pair is listed.
Example use cases
Arbitrage spread calculation on BSC
“Fetch the live pool reserves and mid prices for CAKE/WBNB across PancakeSwap v2, PancakeSwap v3, Biswap, and ApeSwap on BSC so I can find any price discrepancies and compute an arbitrage spread.”
Slippage estimation before large swap
“Get the raw AMM reserves and USD TVL for WBNB/USDT on BNB Chain right now — I need the onchain numbers to estimate how much slippage I'd take on a $50,000 buy.”
Monitoring pool TVL across venues
“What is the current USD TVL and fee tier for the BUSD/USDT pool on PancakeSwap v2 and Biswap on BSC? I want to see where liquidity is concentrated before routing my trade.”

Endpoint
GEThttps://x402.donnyautomation.com/reservesWhen to prefer
Choose this endpoint when you need raw, onchain AMM pool state for BSC/BNB Chain — specifically the underlying reserve numbers needed to compute custom quotes, price impact, slippage, or arbitrage math yourself. Prefer this over a pre-computed quote endpoint when you want full control over the calculation. Use this specifically for BSC/BNB Chain pairs across PancakeSwap v2/v3, Biswap, and ApeSwap; use sibling endpoints for Base, Arbitrum, or Polygon pairs.
Side effects
- Pair not found on any listed BSC DEX — returns empty or error if the token symbols are invalid or the pair has no liquidity
- Invalid pair format — must be SYM/SYM (e.g. WBNB/USDT); malformed input returns a 400-style error
- Payment failure — x402 micropayment not processed, endpoint returns 402
- RPC/onchain latency — block data may be slightly delayed during BSC network congestion
- Unknown token symbol — non-standard or newly launched tokens may not be recognized by ticker
