What it does

This x402 endpoint exposes a Questflow "swarm" agent for personal use. It accepts a text message via HTTP POST and returns a text response from the agent. Payment is handled inline using the x402 protocol: callers must attach a USDC micropayment (on Base Sepolia testnet) in the X-PAYMENT header to unlock each request.

Questflow is a platform for creating autonomous AI "Clones" that aggregate onchain markets (Polymarket, Pump.fun, OKX, Opinion Labs, etc.), discover trading alpha, and execute trades. This particular endpoint is labeled "Personal use" and is discoverable on the Questflow swarm network under the resource identifier `qrn:swarm:68f9d6e4d73a623984833433`. The maximum payment required per call is 500,000 units of USDC (likely 0.50 USDC given 6 decimals) on the Base Sepolia network, with a timeout of up to 1,200 seconds.

Documentation beyond the x402 challenge and the Questflow landing page is not available. There is no OpenAPI spec, no dedicated API docs page, and the endpoint's exact agent capabilities (e.g., which markets it covers, what kinds of queries it handles) are not documented. The schema is minimal: send a JSON body with an `input` string field and receive a JSON response with a `response` string field.

Capabilities

Quality

0.40/ 1.00

The endpoint is live (402 challenge confirmed) with a clear outputSchema, but there is no OpenAPI spec, no dedicated documentation, and the agent's actual capabilities are undocumented. The description and use cases are largely inferred from the Questflow landing page and the x402 challenge metadata.

Warnings

  • —Uses Base Sepolia testnet — not production/mainnet USDC
  • —No API documentation or OpenAPI spec available
  • —Agent capabilities and response quality are unknown — 'Personal use' label is vague
  • —Max timeout of 1200 seconds suggests potentially slow responses
