Query DEX Screener blockchain data for decentralized exchange token info via a pay-per-call AI agent.
What it does
This x402-enabled endpoint exposes a DEX Screener agent hosted on the Questflow platform. DEX Screener tracks decentralized exchange activity by parsing raw blockchain logs with a custom-built indexer. You send a natural-language query as a POST request with an `input` string field, and the agent returns a text response with the requested DEX data.
The endpoint operates on the x402 payment protocol (base-sepolia network) and accepts USDC payments. The maximum amount required per call is 100,000 units (in the token's smallest denomination) with a timeout of up to 1200 seconds. The agent is described as suitable for queries about cryptocurrencies on decentralized exchanges; for centralized exchange queries, the description recommends using a separate Oklink agent, and for ambiguous cases, querying both DEX Screener and CoinGecko agents.
Documentation is sparse — there is no OpenAPI spec, no dedicated docs page, and the only schema information comes from the x402 challenge's `outputSchema`. The Questflow platform (the provider) focuses on AI agent clones for onchain market scanning and trading, but this specific endpoint is a standalone agent query interface rather than a full trading bot.
Capabilities
Use cases
- —Querying real-time token data from decentralized exchanges
- —Looking up trading pairs and liquidity on DEXes
- —Comparing DEX token activity across multiple blockchains
- —Agent-to-agent queries for DEX market intelligence
- —Screening new token launches on decentralized platforms
Fit
Best for
- —AI agents needing on-demand DEX market data via natural language
- —Developers building crypto dashboards that need DEX pair info
- —Automated workflows that require decentralized exchange screening
Not for
- —Centralized exchange data queries (use Oklink or similar)
- —High-frequency trading requiring sub-second latency (1200s max timeout)
- —Users who need a free API without payment infrastructure

Request
{
"input": "What is the current price of PEPE on Uniswap?"
}Response

"response": "PEPE/WETH on Uniswap V2 is currently trading at $0.00001234 with $5.2M in 24h volume."
}Endpoint
Quality
The endpoint is live (402 challenge confirmed) with a clear input/output schema from the x402 challenge, but there is no OpenAPI spec, no dedicated documentation, and the response example is inferred. Pricing details are only partially available from the challenge metadata.
Warnings
- —No OpenAPI or dedicated API documentation available
- —Response format and content are inferred from the outputSchema description — no real response sample captured
- —Payment is on base-sepolia (testnet), which may indicate this is a development/staging endpoint
- —Example response is fabricated based on schema description — actual output may differ
- —Max timeout of 1200 seconds suggests potentially slow agent processing
