Feeds & API

Every listing on this site doubles as a feed. Two formats are available: RSS 2.0 (feed.xml) and JSON Feed 1.0 (feed.json). Same items, same ordering. Use whichever your client supports.

All briefs

RSS: https://feed.craftedsignal.io/feed.xml
JSON: https://feed.craftedsignal.io/feed.json

Items are ordered newest-first. Both feeds return up to 100 items. The JSON feed paginates beyond that. When another page exists, the response includes next_url.

Filtered feeds

Replace <term> and <slug> with the value you want.

Filter	RSS	JSON
Severity	`/severities/<term>/feed.xml`	`/severities/<term>/feed.json`
Type	`/types/<term>/feed.xml`	`/types/<term>/feed.json`
Product	`/products/<slug>/feed.xml`	`/products/<slug>/feed.json`
Vendor	`/vendors/<slug>/feed.xml`	`/vendors/<slug>/feed.json`
Actor	`/actors/<slug>/feed.xml`	`/actors/<slug>/feed.json`
Tag	`/tags/<slug>/feed.xml`	`/tags/<slug>/feed.json`

Severity terms: critical, high, medium, low, rumour. Type terms: threat, coverage, advisory, rumour.

Tips

Slack speaks RSS natively: /feed subscribe https://feed.craftedsignal.io/severities/critical/feed.xml.
Microsoft Teams has an "RSS" connector. Point it at any of the URLs above.
Email aggregators (Buttondown, Feedrabbit, Follow.it) will turn an RSS URL into per-item or daily-digest mail.
Custom integrations can pull feed.json and decode it with your runtime's JSON library. No auth, no rate limit beyond the static-site CDN.

For per-subscriber filter combinations and channel routing (Slack/Teams webhooks, magic-link email confirmation), use the subscribe form instead.
