## 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-dex-liquidity-depth-checker-08350972
```

Example prompt: Before I trade CAKE/USDT on BSC, can you check how deep the liquidity is — tell me if it's DEEP, MODERATE, SHALLOW, or VERY_THIN, how many venues can route the trade, and whether it's dangerously concentrated in a single DEX?

## When to prefer this

Use this endpoint when you need a fast, pre-trade liquidity sanity check specifically on BSC/BNB Chain. Prefer this over generic price endpoints when the concern is slippage, market depth, or venue concentration risk rather than price alone. Choose the BSC-specific version over the Arbitrum, Polygon, or Base siblings when the trade is on BNB Chain.

## Known failure modes

- Unknown or invalid token symbol returns an error — ensure pair is formatted as SYM/SYM (e.g. CAKE/USDT)
- Token pair with no on-chain liquidity on BSC returns no venues found
- Network outage or BSC RPC issues may cause stale or unavailable pool data
- Newly listed tokens may have insufficient indexing and return incomplete results

## How this service works

Pre-trade depth verdict for a pair on BSC / BNB Chain: is this market thin enough to hurt you. Returns depthClass DEEP|MODERATE|SHALLOW|VERY_THIN, totalTvlUsd, venueCount, topVenueShare, midSpreadBps, flags. Requires ?pair=SYM/SYM (e.g. WBNB/USDT). Errors: 400 bad_pair, 404 no_pools, 502 upstream_read_failed. Depth only - NOT a contract audit or honeypot check. Per-venue detail is /liquidity. Bare = BSC; also /polygon /arbitrum /avalanche /optimism /base.

## Output

Returns a liquidity depth classification (DEEP, MODERATE, SHALLOW, or VERY_THIN) based on live pool TVL, the number of DEX venues able to route the trade, the concentration ratio of the largest venue, a flag if only one venue serves this market, and a flag if cross-venue spreads are abnormally wide.
