## 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-1da75471
```

Example prompt: Can you pull the live DexScreener liquidity pools, FDV, 24h volume, and 1h 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 liquidity, orderflow, and market depth data for a specific token on Base, Solana, or Ethereum — especially before executing a swap or assessing slippage risk. Prefer this over general crypto price APIs when you need pool-level detail (FDV, 1h buy/sell pressure, per-pool liquidity) rather than just spot price.

## Known failure modes

- Token symbol or contract address not found on DexScreener — returns empty or error response
- Token exists on an unsupported chain — no pool data returned
- Rate limiting or payment failure via x402 — HTTP 402 response requiring USDC payment
- DexScreener upstream API outage — stale or unavailable data
- Ambiguous token symbol resolves to multiple pools — response may include multiple or unexpected pools

## 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-screener)

## Output

Returns structured data from DexScreener including active liquidity pools, fully diluted valuation (FDV), 24-hour trading volume, and 1-hour buy/sell orderflow pressure for the specified token. Useful for assessing trade depth, slippage risk, and short-term market momentum.
