Chat-based Web3 trading agent powered by Questflow, payable via x402 on Base Sepolia
What it does
Web3 Trader is an x402-enabled AI agent endpoint hosted by Questflow. It accepts a text message via POST and returns a response from an autonomous Web3 trading agent. The endpoint is part of Questflow's "AI Clone" platform, which aggregates onchain markets including Polymarket, Pump.fun, Opinion Labs, and OKX to discover trading opportunities, execute trades, and generate signals.
The endpoint uses the x402 payment protocol on the Base Sepolia testnet, accepting USDC payments (asset 0x036CbD53842c5426634e7929541eC2318f3dCF7e) with a max amount of 500,000 units per request and a timeout of up to 1,200 seconds. The input schema is simple: a single required string field called "input" containing your message to the agent, and the output is a single string "response" field.
Because this endpoint runs on Base Sepolia (a testnet), it is likely intended for development and experimentation rather than production trading. No detailed API documentation, rate limits, or response format examples are available beyond the outputSchema in the x402 challenge. The underlying Questflow platform claims to scan thousands of markets 24/7 and detect patterns, sentiment shifts, and whale movements, but the specific capabilities exposed through this single chat-style endpoint are unclear.

}Response
{
"response": "Based on current scanning, here are top opportunities: ..."
}Endpoint
Quality
The endpoint is live (402 challenge confirmed) with a clear outputSchema defining input/output fields, but there is no API documentation, no usage examples, no OpenAPI spec, and the endpoint runs on a testnet. The response format example is inferred from the schema, not observed.
Warnings
- —Endpoint operates on Base Sepolia testnet — not suitable for production or real-money trading
- —No API documentation or OpenAPI spec available
- —Response format is inferred from outputSchema; no actual response sample observed
- —USDC asset address is testnet USDC, not mainnet
- —Max timeout of 1200 seconds suggests potentially long-running requests
