Pay-per-message AI agent on Questflow's swarm network via x402 micropayments
What it does
This endpoint exposes a Questflow AI agent (swarm) accessible via the x402 payment protocol on the Base Sepolia testnet. Callers send a text message in the request body and receive a text response from the agent. Payment is handled inline via the X-PAYMENT header using USDC (on Base Sepolia), with a maximum cost of 0.50 USDC per request and a timeout of up to 1200 seconds.
Questflow is a platform for creating autonomous AI "Clones" that aggregate onchain markets (Polymarket, Pump.fun, OKX, Opinion Labs, etc.) to discover alpha, execute trades, and generate revenue. This particular endpoint is labeled "Personal use" and appears to be a general-purpose conversational agent within the Questflow swarm infrastructure. The endpoint accepts HTTP POST requests with a JSON body containing an `input` string field and returns a JSON object with a `response` string field.
Note: This endpoint is on a development/testnet domain (api-dev, Base Sepolia network) and uses testnet USDC. No OpenAPI spec, dedicated documentation, or pricing page was found. The exact capabilities and specialization of this specific agent are not documented beyond the generic "Personal use" label.
