## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability bsc-bnb-chain-amm-pool-reserves-live-state-f346c993
```

Example prompt: Pull the current raw pool reserves, mid price, fee tier, and USD TVL for WBNB/USDT across PancakeSwap v2, PancakeSwap v3, Biswap, and ApeSwap on BNB Chain so I can compute my own price impact and slippage.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
