Is this your server? Own a server? ToolFit hosted watch re-checks it every 24 h ($0.25 per 30 days) or 6 h ($0.60) and sends you an HMAC-signed webhook when its tools or grade change: POST https://api.youraitools.co/toolfit/v1/watch. To opt out, see About & opt-out.

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/"}. params: url* |
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. params: none |
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. params: none |
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. params: api_key, url*, label, interval_minutes, watch_terms, webhook_url, part, alert_when |
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. params: api_key, monitor_id* |
fluxproof_list_changes | List recent evidence receipts for a monitor. params: api_key, monitor_id*, limit |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json. Opt-out: how or hello@youraitools.co.
