What it does

This x402-enabled endpoint exposes a conversational AI agent 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 QRN `qrn:swarm:68f8d7d6ff77bdafbaf6823c`. The endpoint is live and returns a valid 402 challenge.

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 subdomain (`api-dev`), and payment is on the Base Sepolia testnet (not mainnet), suggesting this is a development or staging deployment rather than a production service.

Quality

The endpoint is live (402 challenge confirmed) and has a basic outputSchema, but there is no OpenAPI spec, no documentation, no examples, and the listing title/description are generic ('Personal use'). The endpoint is on a dev subdomain using testnet USDC, suggesting it is not production-ready.

Warnings

  • —Endpoint is on a development subdomain (api-dev) and uses Base Sepolia testnet — not suitable for production use
  • —No API documentation, OpenAPI spec, or usage examples are available
  • —The listing description 'Personal use' provides no meaningful information about the agent's capabilities
  • —Response schema is inferred from the outputSchema in the 402 challenge; actual responses may differ
  • —USDC asset address 0x036CbD53842c5426634e7929541eC2318f3dCF7e is the Sepolia testnet token
