Api Endpoint

Forest Web

Preflight one public URL before an agent uses it: verify immediate HTTP reachability, origin status, redirect destination, response headers and cache validators with a bounded HEAD-first probe. GET is used only when HEAD is unsupported. No JavaScript, login, page extraction or availability guarantee. Base mainnet USDC
