Tool	Description	Behaviour
fluxproof_check_now	Run a monitor now and return a source- and hash-bound change receipt. Consumes check quota, stores a receipt and may deliver a configured webhook. Not an idempotent read.	Changes data
fluxproof_create_monitor	Create a monitor using a buyer-owned FluxProof API key. Creates persistent state and performs a baseline check, consuming quota. Not idempotent; do not retry blindly after an uncertain result.	Changes data
fluxproof_get_free_key	Create a free FluxProof API key: one page, checked daily, for 30 days, no card. One per network per month. Use after a successful preflight when the user wants the page watched, then pass the key to fluxproof_create_monitor. The key is shown once: give it to the user and treat it as a secret.	Changes data
fluxproof_list_changes	List recent evidence receipts for a monitor.	Read-only
fluxproof_offer	Return free and paid boundaries and purchase routes without charging. Read this for the free daily plan, $9 paid pass, human checkout and agent payment route. Example: {}. A returned offer is not purchase authorization.	Read-only
fluxproof_preflight	Fetch a public URL and return fetchability, size, final URL, title, and content hash without page content or payment. Start here before creating a monitor. Example: {"url":"https://example.com/"}.	Read-only
