With payments configured, an unpaid request returns HTTP 402 payment requirements.
Unavailable configuration returns HTTP 503; availability flags above must be checked.
Use a wallet-enabled x402 client to inspect the actual challenge, verify the same-host
resource URL, price, USDC asset, network and receiver, and obtain explicit spending
approval before signing or retrying. Never put a wallet private key into a request,
URL, browser page, or MCP arguments. This guide does not sign, pay or auto-retry.
Do not pay twice by calling both HTTP aliases for the same intended adaptation.

MCP: connect to https://www.hybriqx.com/mcp/ using stateless Streamable HTTP.
Read current tools/list schemas or https://www.hybriqx.com/.well-known/mcp/server-card.json.
service_info is free metadata. scale_workout is paid at the same configured price;
it needs an x402-capable wallet client using _meta["x402/payment"].
An ordinary MCP connection alone does not authorize payment.

The client cap is at most 0.05 USDC per paid attempt and per in-memory session; a runtime price above the cap is refused, not automatically approved. LangChain and OpenAI Agents integrations require optional langchain/openai extras. Paid framework tools are disabled unless a trusted operator approval_policy is supplied; model arguments cannot authorize spending. Reuse the tool factory for session limits; production needs a durable external budget/approval ledger. No automatic paid retries. This is a buyer client, not an MCP server or A2A agent.

SYNTHETIC_ILLUSTRATION: static request/response contract illustration only. Not executed, not a paid result, not a verified duration, and not medically approved. execution_time_ms=0.0 is a placeholder, not a latency measurement.
athlete_notes is optional. Submitted workout text, equipment and notes are sent to the configured Google Gemini model. Do not send personal or health information without the athlete's informed consent and appropriate data-handling authorization.
Model-generated adaptations are not medical advice or medically approved workouts. Equipment checks are bounded and cannot verify all movement, medical, or duration constraints. Human review is required, especially for injuries or restrictions. Do not exercise through pain; seek appropriate professional guidance.
The browser app's internal APIs and generated workouts are not advertised paid tools.
