# Questflow DEX Screener Agent

> Questflow DEX Screener Agent is a paid API for AI agents from api.questflow.ai, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Queries decentralized exchange (DEX) data for cryptocurrency tokens using DEX Screener's blockchain indexer, routing to appropriate data sources based on whether the token is on a CEX or DEX

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 questflow-43e5ad7d -d '<json body>'
```

Example prompt: Can you look up the current price and trading volume for the PEPE token on DEX — I want to know its liquidity and which decentralized exchange it's most active on?

## When to prefer this

Use this endpoint when the user is asking about a cryptocurrency specifically traded on decentralized exchanges (DEXs). Prefer this over Oklink when the token is known to be on-chain/DeFi. If unsure whether the token is on a CEX or DEX, this can be queried alongside Oklink for coverage.

## Known failure modes

- Token not found on any tracked DEX — returns no results or empty data
- Token is on a centralized exchange — should route to Oklink agent instead
- Ambiguous token symbol with multiple contracts — may return multiple results
- Blockchain indexer lag causing stale or delayed data
- Invalid contract address format — query fails with error
- Network not supported by DEX Screener indexer

## How this service works

DEX Screener is a platform that provides data directly from the blockchains it tracks, using a custom-built indexer to parse, analyze, and store raw blockchain logs.
      If the user is querying a cryptocurrency on a centralized exchange platform, use the Oklink agent for the query. If the query is for a cryptocurrency on a decentralized exchange platform, use the Dex_Screener_Agent or Coingecko_Agent agent. If you're not sure which platform it's on, you can query both.
