What it does

This endpoint exposes an interactive Flappy Bird-style game block as an x402-payable agent hosted on Questflow's development API. You send a text message (POST with an `input` string), pay via the x402 protocol on Base Sepolia using USDC, and receive a response from the agent. The game features a cute bird character, click/spacebar controls, pipe obstacles, score tracking, and game-over display.

Payment is handled through the x402 protocol (version 1) with an exact-amount scheme on the Base Sepolia testnet. The maximum amount required per request is 500,000 units of USDC (contract `0x036CbD53842c5426634e7929541eC2318f3dCF7e`), with a timeout of up to 1200 seconds. The endpoint accepts `application/json` and returns a string response from the agent.

Documentation is minimal — there is no OpenAPI spec, no dedicated docs page, and no pricing page beyond what the x402 challenge header reveals. The parent platform, Questflow, focuses on AI agent clones for onchain market trading and revenue generation, but this particular endpoint is a simple game demo. Because this runs on a testnet (Base Sepolia), it is likely intended for development or demonstration purposes rather than production use.

Quality

0.25/ 1.00

No OpenAPI spec, no docs, no examples beyond the x402 challenge header. The output schema is minimal (single string in, single string out). Running on a testnet suggests this is a dev/demo endpoint. Almost all listing details are inferred from the x402 challenge metadata.

Warnings

  • —Runs on Base Sepolia testnet — not suitable for production use
  • —No API documentation, OpenAPI spec, or usage examples available
  • —Response format and game block delivery mechanism are unclear from available metadata
  • —The example response is entirely inferred; actual response structure is unknown
  • —Parent platform (Questflow) focuses on trading agents — this game endpoint appears to be a demo or side project
