What it does

This x402-enabled endpoint exposes a conversational AI agent on Questflow's swarm infrastructure. Callers send a POST request with a text message in the `input` field and receive a text `response` from the agent. Payment is handled via the x402 protocol using USDC on the Base Sepolia testnet, with a maximum charge of 0.5 USDC per request (6-decimal token, so 500000 = 0.5 USDC).

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 is identified by the swarm resource ID `qrn:swarm:68f9f4e6c87f09b65914893d`. The endpoint is live and returns a proper 402 challenge when called without payment.

Documentation is extremely sparse — there is no OpenAPI spec, no dedicated API docs page, and the only schema information comes from the x402 challenge's `outputSchema` field. The agent's specific capabilities, personality, or domain expertise are not described beyond the generic "Personal use" label. Callers should treat this as an experimental testnet endpoint.

Quality

0.35/ 1.00

The endpoint is live (402 challenge confirmed) and has a minimal outputSchema, but there is no OpenAPI spec, no dedicated documentation, no usage examples, and the agent's purpose is described only as "Personal use." Almost all listing details are inferred from the x402 challenge payload and the Questflow landing page.

Warnings

  • —Testnet only: payments use USDC on Base Sepolia, not mainnet
  • —No API documentation or OpenAPI spec available
  • —Agent purpose and capabilities are undocumented beyond 'Personal use' label
  • —Response example is inferred/fabricated from the outputSchema; no real response was captured
  • —The endpoint is on a dev subdomain (api-dev), suggesting it may be unstable or experimental
