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:68f87f257aa0f71b3c5e5fe2`. 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 docs page, and no detailed description of what this specific agent does beyond accepting a string input and returning a string response. The output schema from the 402 challenge is the only technical reference available. Because this runs on Base Sepolia (a testnet), it is likely intended for development or experimentation rather than production use.

Quality

0.35/ 1.00

The endpoint is live (402 challenge confirmed) and has a minimal output schema, but there is no OpenAPI spec, no documentation, no examples, and the description is just "Personal use". The testnet-only payment and lack of any detail about the agent's capabilities make this effectively a stub listing.

Warnings

  • —No API documentation or OpenAPI spec available
  • —Runs on Base Sepolia testnet — not production/mainnet
  • —Agent purpose and capabilities are entirely undocumented beyond 'Personal use'
  • —Response schema is inferred from the 402 challenge outputSchema only
  • —The example response is fabricated to match the schema; actual behavior is unknown
