## 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 vape-liquidity-check-base-token-dex-liquidity-depth-7ba5bfd8
```

Example prompt: Can you check the liquidity depth and top DEX pair for this Base chain token — 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913?

## When to prefer this

Use this endpoint when you need real on-chain liquidity depth and top DEX pair data for a Base chain token, sourced from authoritative providers (GoPlus, DexScreener, DefiLlama) without simulation. Prefer this over generic DEX APIs when you specifically need Base chain liquidity analysis with multi-source aggregation.

## Known failure modes

- Invalid or non-existent token address returns error or empty result
- Token exists on a different chain than Base (8453) and returns no data unless chain override is provided
- Token has no DEX listings and returns empty liquidity data
- Rate limiting or upstream data provider (GoPlus/DexScreener/DefiLlama) unavailability causes failure
- Malformed address format returns validation error

## How this service works

VAPE liquidity_check — Liquidity depth + top pair DEX for a Base token. Real on-chain/market data, no simulation.

## Output

Returns liquidity depth metrics and the top DEX pair for the given Base token, sourced from real GoPlus, DexScreener, and DefiLlama data — including pool size, best trading venue, and related liquidity indicators.
