What it does

This x402-enabled endpoint exposes a conversational AI agent hosted on Questflow's swarm infrastructure. Callers send a text message via POST and receive a text response from the agent. Payment is handled through the x402 protocol using USDC on the Base Sepolia testnet, with a maximum charge of 0.5 USDC per request.

Questflow is a platform for creating autonomous AI "Clones" that aggregate onchain markets (Polymarket, Pump.fun, OKX, Opinion Labs, etc.) to discover trading alpha, execute trades, and generate revenue. This particular endpoint is labeled "Personal use" and appears to be a single agent within Questflow's swarm system, identified by the resource name `qrn:swarm:68f8d5caf4709fbe67edf0b8`. The endpoint is live and returns a valid 402 challenge on POST requests.

Documentation is extremely sparse. There is no OpenAPI spec, no dedicated docs page, and no detailed description of what this specific agent does beyond accepting a string input and returning a string response. The endpoint runs on a development API (`api-dev`), suggesting it may be experimental or unstable. Pricing is in testnet USDC, so real funds are not at stake, but this also means the endpoint is not production-grade.

The endpoint is live (402 challenge confirmed) and has a basic outputSchema, but there is no OpenAPI spec, no documentation, no examples, and the description is just 'Personal use'. It runs on a dev API with testnet tokens, suggesting experimental status. Almost everything beyond the x402 challenge must be inferred.

Warnings

  • —Endpoint is on a development API (api-dev) — may be unstable or experimental
  • —Payment uses Base Sepolia testnet USDC — not real funds, not production-ready
  • —No documentation, no OpenAPI spec, and no detailed description of agent capabilities
  • —The existing title and description ('Personal use') provide no meaningful information about what this agent does
  • —Response schema is inferred from outputSchema; actual response format is unverified
