Mail Security Tools
Mail Security Tools API: Prepaid email setup watch: up to 25 domains for 30 days, webhook on change. Pay once, then each domain's SPF, DMARC, DKIM (common selectors), MX and score are re-checked about once a day for 30 days. When something changes or breaks you get an HMAC-signed JSON POST at your https webhook_url (event watch.changed, kind changed|broke, before/after). A watch.created POST is sent right away. Webhook only, no email. Free status at GET /v1/watch/{watch_id}. Bad input 400, never

Categories and declared capabilities
Topic categories are derived from publisher text for discovery, not independently verified capabilities.
The registry does not provide a verified tools list. See the observations, when available, for any tools/list check; a published tools list does not establish that execution succeeds.
Evidence, with its limits.
This listing is indexed. Any domain claim or endpoint observation appears separately with its date and limited scope. No payment execution, factual accuracy or safety certification is inferred.
