Pay-per-message AI agent endpoint on Questflow's swarm network via x402 micropayments
What it does
This is an x402-enabled endpoint hosted on Questflow's development API that exposes a conversational AI agent (swarm agent). 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 500,000 units (likely 0.50 USDC given 6-decimal USDC) per request.
Questflow is a platform for creating autonomous AI "Clones" that aggregate onchain markets (Polymarket, Pump.fun, OKX, Opinion Labs) to discover alpha, execute trades, and generate revenue. This particular endpoint is labeled "Personal use" and appears to be a single agent within Questflow's swarm infrastructure. The endpoint is live and returns a proper 402 challenge when called without payment headers.
Documentation is extremely sparse — there is no OpenAPI spec, no dedicated docs page, and the endpoint's specific capabilities beyond accepting a text input and returning a text response are unknown. The agent's domain expertise, context window, and behavioral characteristics are not documented. The endpoint runs on a development subdomain (`api-dev`), suggesting it may not be production-stable. Payment is on Base Sepolia (a testnet), which means this is likely a test/dev deployment rather than a production service.
Capabilities
Use cases

"response": "I am currently scanning prediction markets and crypto markets for opportunities."
}Endpoint
Quality
The endpoint is live (402 challenge confirmed) and has a basic outputSchema describing input/output fields. However, there is no OpenAPI spec, no dedicated documentation, no usage examples, and the endpoint is on a development subdomain using testnet tokens. The listing title 'Personal use' provides almost no information about the agent's actual capabilities.
Warnings
- —Development endpoint (api-dev subdomain) — may be unstable or removed without notice
- —Payment uses Base Sepolia testnet USDC, not mainnet — this is likely a test deployment
- —No API documentation, OpenAPI spec, or usage examples available
- —Agent capabilities and domain expertise are completely undocumented
- —The 'Personal use' label provides no meaningful description of what the agent does
