Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-free?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically want to discover x402-protocol services that are free (zero or near-zero cost), ranked by authentic on-chain usage signals (30-day calls and unique paying wallets). It is preferable over generic API directories when you need verifiable, blockchain-sourced popularity metrics and a tamper-evident snapshot receipt. Use it when building agents that need to auto-select free x402 services or when auditing the free-tier x402 marketplace.
