Tools
| 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: each call creates a new monitor. | Changes data |
| fluxproof_get_free_key | Create a free FluxProof API key: one page, checked daily, for 30 days, no card. One per internet connection (IP address) per month. The key is returned once and is a secret credential. | 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. 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 charges nothing. | Read-only |
| fluxproof_preflight | 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/"}. | Read-only |
