POST https://a-upgradenet.com/x402/endpoint-check · 2 observations
x402 Endpoint Check: verifies that a seller's x402 endpoint is alive and payable before you spend. Use before paying an unknown endpoint, or to monitor your own. Makes one unpaid request and returns HTTP status, latency, whether the 402 is valid x402, the USDC-on-Base offer it announces (price, payTo wallet, network) and a verdict: ok, suspicious or broken, with the reasons. Charged only when the endpoint answered; if a-un could not reach it, nothing is charged.

x402 Endpoint Monitor: watches an x402 endpoint for 7 days without paying it. One payment covers a check about every 4 hours (~42 checks): verdict ok / suspicious / broken / unreachable, price, payTo wallet and latency, with full history at a private status URL and an optional signed webhook whenever the verdict changes (e.g. the endpoint goes down or changes its wallet). Use it to monitor your own paid routes or a seller you depend on. Charged only once the monitor is created.

Counts describe directory coverage, including testnets. Each resource groups the same URL, HTTP method or MCP tool across sources. A catalog sighting records published terms. A live 402 records the endpoint’s reply to an unpaid request.
