# Token DEX Liquidity Snapshot & Change Monitor

> Token DEX Liquidity Snapshot & Change Monitor is a paid API for AI agents from api.fadeandco.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-29).

Returns a real-time snapshot of a token's DEX pool liquidity across all pairs, optionally computing % change and a DROP/DRAIN alert flag vs. a previously saved liquidity value.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 token-dex-liquidity-snapshot-change-monitor-b52c50b6
```

Example prompt: Check the current DEX pool liquidity for token 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — my last recorded deepest-pool liquidity was $11,490,316, so tell me the percent change and whether there's a DROP or DRAIN alert.

## When to prefer this

Use this endpoint when you need a real-time, stateless liquidity snapshot for a specific token across all its DEX pools, especially when you want to detect liquidity drain or rug-pull signals by comparing to a previously saved value. Prefer this over on-chain RPC calls when you want aggregated multi-DEX coverage via DexScreener without managing your own data pipeline. Not suitable if you need historical liquidity time-series or lock expiry data.

## Known failure modes

- Token address not found on DexScreener — returns empty pools array
- Unsupported chain value — may return error or empty result
- No liquidity data available for very new or low-volume tokens
- previousLiquidityUsd not passed — changePercent and alert still computed but relative to zero
- Network timeout from DexScreener upstream — intermittent failures possible

## How this service works

Snapshot of a token's DEX pool liquidity now (DexScreener, deepest pair and every pair's USD liquidity). Stateless: pass the liquidityUsd you saved last time as previousLiquidityUsd and it returns the % change and a DROP/DRAIN flag. It keeps no history itself and does not show lock expiry dates.

## Output

Returns a JSON object with: the deepest pool's current USD liquidity, a list of all DEX pools with their pair addresses and USD liquidity, a % change vs. the previousLiquidityUsd you supplied, a DROP/DRAIN/STABLE alert flag, the source DexScreener URL, the chain and token address, and a timestamp. Does not include lock expiry dates or historical data beyond the single comparison point you pass in.
