What it does

This x402-enabled endpoint exposes a Questflow "swarm" agent that accepts a text message and returns an AI-generated response. Payment is handled via the x402 protocol on the Base Sepolia testnet using USDC (asset 0x036CbD53842c5426634e7929541eC2318f3dCF7e), with a maximum charge of 0.5 USDC per request (500000 in token units). 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.

Questflow is a platform focused on autonomous AI agents ("Clones") that operate across onchain markets such as Polymarket, Pump.fun, OKX, and Opinion Labs. The specific agent behind this endpoint is not well-documented — the listing title is simply "Personal use" and no further details about the agent's specialization, training, or capabilities are provided. The endpoint is on a development/staging domain (api-dev.intra-tls2.dctx.link), suggesting it may not be production-ready.

No OpenAPI spec, dedicated documentation, or pricing page was found for this endpoint. The only schema information comes from the x402 challenge's `outputSchema` field. Users should treat this as an experimental, testnet-only endpoint with limited guarantees around uptime, response quality, or stability.

No OpenAPI spec, no dedicated docs, no examples, and the endpoint is on a dev/staging domain using testnet tokens. The only schema info comes from the x402 challenge outputSchema. The agent's purpose and capabilities are entirely unspecified beyond 'Personal use'.

Warnings

  • —Endpoint is on a development domain (api-dev.intra-tls2.dctx.link) — likely not production-ready
  • —Uses Base Sepolia testnet, not mainnet — USDC payments have no real monetary value
  • —No documentation, OpenAPI spec, or /docs endpoint found
  • —Agent purpose and behavior are undocumented; listing title is just 'Personal use'
  • —Response example is inferred/fabricated since no actual successful response was captured
