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 a Web3 trading agent. The endpoint uses the x402 payment protocol on the Base Sepolia testnet, accepting USDC payments with a maximum amount of 500,000 units (likely 0.50 USDC given 6-decimal USDC) per request.

The underlying platform, Questflow, describes itself as an AI Clone system that aggregates onchain markets including Polymarket, Pump.fun, Opinion Labs, and OKX. The platform's agents scan markets, detect patterns and sentiment shifts, and execute trades autonomously. However, the specific capabilities of this particular "Web3 Trader" agent endpoint are not documented beyond the generic description. The output schema indicates a simple request/response chat interface: you send a string message and receive a string response.

This endpoint is live and returns a proper 402 challenge. No OpenAPI spec, dedicated docs, or usage examples are available beyond the x402 challenge metadata. The endpoint is on a development API domain (api-dev), suggesting it may be a testnet/staging deployment rather than production-grade.

Quality

0.45/ 1.00

The endpoint is live with a valid 402 challenge and a basic output schema, but there are no dedicated docs, no OpenAPI spec, no usage examples, and the endpoint is on a dev/testnet domain. The agent's specific capabilities are unclear beyond the generic 'Web3 Trader' label.

Warnings

  • —Endpoint is on a development domain (api-dev) and uses Base Sepolia testnet — not production
  • —No API documentation, OpenAPI spec, or usage examples available
  • —The example response is inferred; actual agent behavior is undocumented
  • —Specific trading capabilities of this agent are unknown — the Questflow platform description is generic
