# x402.clashofcoins.com

This host serves agents that need to confirm end-to-end x402 payment settlement and service availability for the Clash of Coins platform before attempting higher-value operations. It is a diagnostic endpoint, not a commerce or data endpoint — it does not expose game data, NFT listings, pricing, or purchase flows.

## When to use this host

Use this host when an agent needs to verify that the Clash of Coins x402 gateway is operational before committing to a higher-cost transaction, or to confirm that x402 payment infrastructure is settling correctly on Base. Do not use it for retrieving game data, NFT prices, shop inventory, or executing purchases — those require the sale or shop endpoints on the Clash of Coins platform. This is not a free ping; it requires a settled x402 payment, so it should not be used as a routine liveness check where cost matters. If the agent only needs a no-cost reachability test, this host is not appropriate.

### `fetch-cheap-health-status`

**Cheap Health Check** — Performs a low-cost x402 payment-gated health probe against the Clash of Coins gateway and returns aggregated service status, checkout configuration, and x402 probe details for $0.001 USDC on Base.

*Use when:* Use when an agent needs to verify that the Clash of Coins x402 gateway and its downstream checkout services (sale, shop) are operational, or to confirm x402 payment settlement is functioning end-to-end at minimal cost.

*Not for:* Do not use for retrieving live pricing, executing purchases, or fetching game/NFT data; use the appropriate sale or shop endpoints instead. Not a substitute for a free ping — this endpoint requires a settled x402 payment.
