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 is a blockchain data platform that uses a custom-built indexer to parse, analyze, and store raw blockchain logs from decentralized exchanges. The agent accepts natural-language queries about cryptocurrencies traded on DEXs and returns text responses with relevant on-chain data.
The endpoint is live and responds with an x402 payment challenge on Base network, accepting USDC (asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maximum cost of 100,000 units (0.10 USDC at 6 decimals) per request. Callers POST a JSON body with a single `input` string field containing their query, and receive a JSON response with a `response` string field. The maximum timeout is 1200 seconds, suggesting the agent may perform multi-step lookups.
The agent description suggests it can be used alongside companion agents (Oklink for centralized exchanges, CoinGecko for additional DEX coverage). Documentation beyond the x402 challenge schema is not available — there are no OpenAPI specs, dedicated docs pages, or usage examples from the provider. Questflow is the hosting platform that powers this agent endpoint.
Capabilities
Use cases
- —Query real-time token data from decentralized exchanges via natural language
- —Look up liquidity pool stats, price, and volume for DEX-traded tokens
- —Integrate DEX screening into an autonomous trading or research agent pipeline
- —Compare DEX token data alongside centralized exchange data from companion agents
Fit
Best for
- —AI agents needing programmatic access to DEX token data
- —Developers building crypto research or trading bots
- —Users who want natural-language queries against on-chain DEX data
Not for
- —Centralized exchange data lookups (use Oklink or similar agents instead)
- —High-frequency trading requiring sub-second latency (max timeout is 1200s)
- —Users needing free or unauthenticated access (requires x402 USDC payment)
Quick start
curl -X POST https://api.questflow.ai/x402/agent/qrn:agent:687df68ab234010b7d331717 \
-H "Content-Type: application/json" \
-H "X-PAYMENT: <x402-payment-header>" \
-d '{"input": "What is the current price and volume of PEPE on Uniswap?"}'Example
Request
{
"input": "What is the current price and 24h volume of PEPE on Uniswap?"
}Response
{
"response": "PEPE/WETH on Uniswap V2: Price $0.00001234, 24h Volume $12.5M, Liquidity $8.2M."
}Endpoint
Quality
The endpoint is live with a valid x402 challenge and a clear input/output schema, but there are no dedicated docs, no OpenAPI spec, no usage examples, and no detailed feature documentation beyond the brief agent description. Response example is inferred.
Warnings
- —No OpenAPI or dedicated documentation available from the provider
- —Response format and content are inferred from the outputSchema description; no real response sample was captured
- —Agent description contains routing instructions for companion agents (Oklink, CoinGecko) that are not part of this endpoint
- —Max timeout of 1200 seconds suggests potentially long response times
