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.
Tools: pw_health pw_snapshot pw_watch_status pw_stats skills_list_tool read_skill
pw_health | Liveness check for the Perimeter Watch API. Returns ok, service, version. Call first to verify connectivity before pw_snapshot. params: none |
pw_snapshot | Run a free one-time external-perimeter scan on a domain you control.
Checks TLS certificate expiry, domain renewal status, dangling CNAME
takeover risk, and CT-log lookalike domains. Returns a rating plus
per-check detail. NOT idempotent (each call consumes rate limit);
takes 20-60s; rate-limited to 3 scans per IP per 24h.
Args:
domain: the domain to scan (e.g. example.com)
authority: MU params: domain*, authority* |
pw_watch_status | Check whether a domain is enrolled on a paid weekly monitoring plan.
Returns enrollment status. Paid plans add weekly re-scans with email
briefs. Read-only lookup.
Args:
domain: the domain to look up (e.g. example.com)
params: domain* |
pw_stats | Service funnel counters: page views, snapshots run, paid registrations. Read-only. params: none |
skills_list_tool | List this product's skills. Each entry carries the SKILL.md URI,
its name and description, verbatim frontmatter, and a per-file
sha256 manifest. Read a body with `read_skill`. params: none |
read_skill | Read a product skill file by its skill:// URI.
Args:
uri: e.g. skill://<product>/<skill-name>/SKILL.md
Get valid URIs from `skills_list_tool`.
params: uri* |
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.
