What it does

This endpoint exposes an AI agent ("new creation") on Questflow's swarm infrastructure via the x402 payment protocol. Callers send a POST request with a JSON body containing an `input` string (a message to the agent) and receive a `response` string back. Payment is handled through the x402 challenge-response flow using USDC on the Base Sepolia testnet, with a maximum amount of 500,000 units (likely 0.50 USDC given 6-decimal USDC) per request and a timeout of up to 1,200 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 appears to be a developer/testnet instance — it runs on Base Sepolia rather than mainnet, and the agent's name and description are both simply "new creation," suggesting it may be a freshly created or template agent rather than a production-tuned one.

Documentation is extremely sparse. There is no OpenAPI spec, no dedicated docs page, and no detailed description of what this specific agent does beyond accepting a text message and returning a text response. The x402 challenge and outputSchema are the only technical references available. Prospective callers should treat this as an experimental/testnet endpoint.

Capabilities

Use cases

  • —Sending natural-language queries to an autonomous AI agent and receiving text responses
  • —Testing x402 micropayment flows against a live agent on Base Sepolia
  • —Integrating Questflow swarm agents into automated pipelines via HTTP POST

Fit

Best for

  • —Developers experimenting with x402 payment protocol integrations

  • —Exploring Questflow's swarm agent infrastructure

Not for

  • —Production workloads requiring mainnet payments and SLAs
  • —Users needing detailed, documented API contracts or OpenAPI specs
  • —Non-crypto use cases where standard API auth is preferred over x402

Quality

0.35/ 1.00

The endpoint is live (402 challenge confirmed) and has a minimal outputSchema, but there is no OpenAPI spec, no documentation, no examples, and the agent name/description are generic placeholders ("new creation"). This is effectively a stub listing on a testnet.

Warnings

  • —Running on Base Sepolia testnet — not suitable for production use
  • —Agent name and description are both 'new creation', suggesting a template or placeholder
  • —No API documentation, OpenAPI spec, or usage examples available from the provider
  • —Response example is inferred from the outputSchema, not from an actual observed response
  • —Maximum timeout of 1200 seconds suggests potentially long-running agent tasks
