# DEX Liquidity, Slippage & Orderflow Audit API

> DEX Liquidity, Slippage & Orderflow Audit API is a paid API for AI agents from prompt-guard.agentdiet.dev, paid per call via MPP, $0.015/call, status unknown (last checked 2026-10-21).

Fetches live DEX liquidity pool data, FDV, 24h volume, and 1-hour buy/sell orderflow pressure for a given token on Base, Solana, or Ethereum via DexScreener.

## 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 prompt-guard-agentdiet-dev-dex-liquidity-slippage-orderflow-audit-api-6c6a16c5
```

Example prompt: Pull the live DEX liquidity depth, FDV, 24h volume, and 1-hour buy/sell orderflow pressure for AERO on Base so I can see if there's enough depth to trade without major slippage.

## When to prefer this

Choose this endpoint when you need real-time DEX market microstructure data — specifically liquidity depth, orderflow directional pressure, FDV, and volume — for tokens on Base, Solana, or Ethereum. Prefer it over generic price APIs when you need to assess trade execution feasibility, detect buy/sell imbalances, or audit token market health before transacting.

## Known failure modes

- Token symbol or contract address not found on any supported chain — returns empty or error response
- Token exists but has no active DEX liquidity pools — returns zero or null liquidity values
- Invalid or malformed contract address input — may return 400 or empty result
- DexScreener data temporarily unavailable — may return stale or error response
- Payment failure via x402 protocol — HTTP 402 returned if USDC payment not processed

## How this service works

Fetches live DexScreener liquidity pools, FDV, 24h volume, and 1h buy/sell orderflow pressure. (Live x402 v2, IETF MPP & MCP endpoint at https://prompt-guard.agentdiet.dev/v1/dex-liquidity-depth-oracle)

## Output

Returns live DEX pool data including available liquidity, fully diluted valuation (FDV), 24-hour trading volume, and 1-hour directional orderflow (buy vs sell pressure) for the queried token across Base, Solana, and/or Ethereum DEX pools sourced from DexScreener.
