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 QRN `qrn:swarm:68f89b6c88e91d0ba6c955be`. 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 is on a dev subdomain (`api-dev`) and uses a testnet (Base Sepolia), suggesting this is a development/staging deployment rather than production.

Quality

0.35/ 1.00

The endpoint is live (402 challenge confirmed) and has a minimal outputSchema describing input/output fields, but there is no OpenAPI spec, no documentation, no usage examples, and the description is just "Personal use". The endpoint runs on a testnet (Base Sepolia), suggesting it is not production-ready. The response example is inferred, not observed.

Warnings

  • —Endpoint is on Base Sepolia testnet — not suitable for production use
  • —No API documentation available; the only schema comes from the x402 challenge
  • —Hosted on a dev subdomain (api-dev), suggesting staging/development status
  • —The agent's actual capabilities and behavior are unknown — 'Personal use' is the only description provided
  • —Response example is inferred from the outputSchema, not from an actual observed response
