How do I get started?
Choose an available plan here. Select an existing application or create your first one during setup, save its API key, and activate your plan. Then use the key in the request builder. Requests call the gateway for real and count against your plan.
Do free requests reset every month?
Check the allowance period on each plan. A one-time allowance does not reset. A monthly free allowance renews on the subscription anniversary. Free allowances are per application.
Why are some plans unavailable for activation?
Their published pricing is available for comparison. Free allowances can be activated here; commercial plans with active checkout can be purchased. Custom enterprise tiers require contacting the provider directly.
What does the trust score tell me?
The score summarizes recorded catalog verification checks. Review the breakdown for individual signals; it is not an uptime or performance guarantee.
