Read key, no browser: POST https://api.loyalspark.online/x402-gateway/register-agent. HTTP 402 is $0.01 USDC on Base. Pay it and do not send an API key. You receive lsk_ once, scope read only: list your programs, rewards, balances, and analytics. That key cannot mint, deploy a program, create rewards, or trade. A new wallet gets a 45-day Pro trial (5 agents, 10,000 calls/month), then Free (1 agent, 200 calls/month, 1,000 tokens minted/month, 1.25% mint fee) unless that wallet pays.

How these numbers are made
Each listing is called on a schedule without paying. Listings with usage or a verified owner are checked about every 30 minutes, others about every 6 hours. Uptime is the share of passing checks over 30 days, averaged across this provider's listings. Trust scores follow the published method. The figures on this page can be a few minutes behind the latest checks, and listings hidden after review aren't counted.
