AI agent that plans travel itineraries and train tickets (Chinese-language, pay-per-request via x402)
What it does
This endpoint exposes a Questflow-hosted AI swarm agent designed to plan travel itineraries and train tickets (规划行程，规划车票). It accepts a natural-language text input via HTTP POST and returns an agent-generated response. The service is gated behind 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 and a generous 1,200-second timeout.
The agent is part of the Questflow platform, which provides an AI clone/agent infrastructure for various use cases. Based on the x402 challenge metadata and the endpoint's description, this particular agent appears to be Chinese-language oriented, focused on travel planning tasks such as route optimization and train ticket booking assistance. The input/output schema is simple: send a JSON body with an "input" string field containing your message, and receive a JSON response with a "response" string field.
Documentation beyond the x402 challenge is sparse. There is no OpenAPI spec, no dedicated docs page, and the crawled site content focuses on Questflow's broader AI clone trading product rather than this specific travel-planning agent. The endpoint is live and returns a valid 402 challenge, confirming it is operational on the Base Sepolia testnet.

Quality
The endpoint is live with a valid 402 challenge and a clear input/output schema, but there is no OpenAPI spec, no dedicated documentation, and the crawled site content does not describe this specific agent. The example response is entirely inferred. The endpoint runs on a testnet (Base Sepolia), limiting production utility.
Warnings
- —No OpenAPI or dedicated documentation available for this endpoint
- —Running on Base Sepolia testnet — not suitable for production payments
- —Agent description and functionality are in Chinese; English support is unconfirmed
- —Example response is fabricated for illustration — actual output format may differ
- —The Questflow landing page describes a trading/prediction market product, not travel planning — this agent's capabilities are only known from its title
