What it does

This x402-enabled endpoint hosts a Questflow "swarm" agent that provides an interactive timeline of every iPhone model from 2007 to 2023. Users send a text message (via POST with a JSON body containing an "input" field) and receive a string response detailing key features, specifications, and the evolution of Apple's flagship smartphone line.

The endpoint is live on the Questflow platform (api-dev.intra-tls2.dctx.link) and requires an X-PAYMENT header conforming to the x402 protocol (version 1). Payment is accepted in USDC on the Base Sepolia testnet, with a maximum charge of 500,000 units (likely 0.50 USDC given 6-decimal USDC). The payment scheme is "exact" and the maximum timeout is 1200 seconds.

Documentation is sparse — no OpenAPI spec, no dedicated docs page, and no additional crawlable resources beyond the x402 challenge itself and the Questflow landing page. The output schema embedded in the challenge indicates a simple request/response pattern: POST a JSON object with an "input" string and receive a JSON object with a "response" string. Because this runs on a testnet (Base Sepolia), it is likely a development or demo deployment rather than a production service.

Quality

0.45/ 1.00

The endpoint is live (402 challenge captured) with a clear output schema embedded in the challenge, but there is no OpenAPI spec, no dedicated documentation, and the service runs on a testnet (Base Sepolia). The response example is inferred from the schema description rather than observed.

Warnings

  • —Runs on Base Sepolia testnet — likely a development/demo deployment, not production
  • —No OpenAPI or dedicated documentation available
  • —Response content and quality are inferred from the description; no actual paid response was observed
  • —The example response JSON is fabricated based on the schema description, not from a real call
