Tools

• fluxproof_check_now ~160 tokens
  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.
• fluxproof_create_monitor ~358 tokens
  Create a monitor using a buyer-owned FluxProof API key. Creates persistent state and performs a baseline check, consuming quota. Not idempotent: each call creates a new monitor.
• fluxproof_get_free_key ~82 tokens
  Create a free FluxProof API key: one page, checked daily, for 30 days, no card. One per network per month. The key is returned once and is a secret credential.
• fluxproof_list_changes ~165 tokens
  List recent evidence receipts for a monitor.
• fluxproof_offer ~124 tokens
  Return free and paid boundaries and purchase routes without charging. Returns the free daily plan, the $9 paid pass (30 days paid once; when offered, also $9 a month through the human checkout, cancel any time), the human checkout link and the agent payment route. Example: {}. Reading the offer char
• fluxproof_preflight ~204 tokens
  Fetch a public URL and return fetchability, size, final URL, title, and content hash without page content or payment. How it works: given one public page address, FluxProof fetches it once and says whether it can watch it; nothing is created or charged. Example: {"url":"https://example.com/"}.
