What it does

This is an x402-enabled endpoint hosted on Questflow's development API (api-dev.intra-tls2.dctx.link) that exposes a swarm agent for personal use. The endpoint accepts a POST request with a text message and returns a string response from the agent. Payment is handled via the x402 protocol using USDC on the Base Sepolia testnet, with a maximum charge of 0.50 USDC per request (500000 in token units) and a timeout of up to 1200 seconds.

Questflow is a platform focused on AI "Clones" that aggregate onchain markets (Polymarket, Pump.fun, OKX, Opinion Labs) for autonomous trading, alpha discovery, and revenue generation. This particular endpoint appears to be a general-purpose conversational agent within Questflow's swarm infrastructure, though the exact capabilities and specialization of the agent behind this endpoint are not documented beyond the generic label "Personal use."

Notably, this is a development/testnet endpoint (Base Sepolia, api-dev subdomain), so it should not be treated as production-grade. There is no OpenAPI spec, no dedicated documentation page, and no detailed description of what the agent actually does beyond accepting a message and returning a response. The output schema is minimal: input is a string message, output is a string response.

Quality

0.25/ 1.00

The endpoint has a valid x402 challenge with a minimal input/output schema, but there is no OpenAPI spec, no documentation, no examples, and the description is just 'Personal use'. The agent's actual capabilities are unknown. This is a testnet/dev endpoint.

Warnings

  • —Development/testnet endpoint (api-dev subdomain, Base Sepolia network) — not production-ready
  • —No OpenAPI spec or documentation available
  • —Agent capabilities are entirely undocumented; 'Personal use' is the only description
  • —The example response is fabricated to illustrate the schema; actual agent behavior is unknown
  • —maxAmountRequired of 500000 USDC units (0.50 USDC) is on a testnet token, not real funds
