What it does

This x402-enabled 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 through the x402 protocol using USDC on the Base Sepolia testnet, with a maximum charge of 0.5 USDC per request (assuming 6-decimal USDC).

Questflow is a platform focused on autonomous AI agents ("Clones") that aggregate onchain markets such as Polymarket, Pump.fun, OKX, and Opinion Labs. The platform's agents scan markets, execute trades, and generate signals. This particular endpoint is labeled "Personal use" and appears to be a general-purpose conversational agent within the Questflow swarm infrastructure. The exact capabilities of the agent behind this endpoint are not documented beyond the generic input/output schema.

The endpoint is live and returns a valid x402 challenge on POST requests. However, there is no OpenAPI spec, no dedicated documentation, and no detailed description of what the agent actually does or what domain knowledge it has. The endpoint is on a development subdomain (api-dev), suggesting it may be a staging or test deployment rather than a production service.

Capabilities

Use cases

  • —Sending a text query to a Questflow AI agent and receiving a response
  • —Integrating a pay-per-message AI agent into an automated workflow
  • —Testing x402 micropayment flows with a conversational agent on Base Sepolia

Fit

Best for

  • —Developers experimenting with x402 payment protocol integrations
  • —Users wanting to interact with Questflow swarm agents programmatically
  • —Testing micropayment-gated AI agent interactions on a testnet

Not for

  • —Production workloads requiring guaranteed uptime (this is a dev endpoint)
  • —Users needing detailed documentation or predictable agent behavior
  • —Anyone expecting free access — every request requires an x402 USDC payment

The endpoint is live and returns a valid x402 challenge with an outputSchema, but there is no documentation, no OpenAPI spec, and the agent's actual capabilities are completely undescribed. The 'Personal use' label and dev subdomain suggest this is a test or staging deployment. The response example is inferred from the outputSchema, not observed.

Warnings

  • —Endpoint is on a development subdomain (api-dev), suggesting non-production status
  • —No documentation or OpenAPI spec available
  • —Agent capabilities and domain knowledge are entirely undocumented
  • —Payment uses Base Sepolia testnet — not real money, likely a test environment
  • —The response example is inferred from the outputSchema, not from an actual observed response
