  • account — Your balance, totals, limits, and recent calls. Requires Authorization: Bearer <gwk_ key>.
  • call_service — Call a catalog service through the gateway. The gateway pays the upstream x402 USDC price from its own wallet and deducts your prepaid credits (upstream price + 25% markup, min $0.005). Requires an account key with credits.
  • create_account — Create a gateway account. Returns your secret key (gwk_…) - store it; it is shown only once. New accounts start at 0 credits.
  • create_owner_key — One-time: mint a separate OWNER key (gwo_…) for the human supervisor. After this, the gwk_ agent key can spend and TIGHTEN limits but never loosen or clear them; only the owner key can. Shown once - the human should store it where the agent can't read it. Requires Authorization: Bearer <gwk_ key>.
  • create_topup_link — Create a hosted card-payment link (Stripe Checkout) that adds $5, $10 or $20 of credits to YOUR account. Give the returned url to your human to open and pay - no crypto wallet needed; credits land 1:1 within seconds of payment. Requires Authorization: Bearer <gwk_ key>.
  • get_service — Full detail for one catalog service: grade breakdown, live price, our price (incl. markup), input schema, output example. Free.
  • get_service_history — Daily probe history for one catalog service (UTC days): uptime %, 402/2xx %, p50/p95 latency, grade per day, price changes, probe counts. Probed every 6 hours. Free.
  • list_services — Search the graded catalog of x402 services (the x402 Bazaar + independent indexes), ranked by real 30-day demand and agent-usability grade (A-F). Free.
  • set_limits — Configure YOUR account's spending guardrails, enforced on every call_service: max_call_usd (refuse any call charging more), daily_usd (rolling-24h charge budget), min_grade (refuse services graded below it), allow (exact service-id allowlist). Send only fields to change; null clears a field. Requires Authorization: Bearer <gwk_ key>.
  • top_up_info — How to add credits (x402 USDC, or a card checkout link via create_topup_link).
