Example prompt: Can you pull up the AIS Labs historical daily CVE brief for September 27, 2026 so I can see which vulnerabilities were ranked highest that day?

## When to prefer this

Choose this endpoint when you need historical CVE priority data for a specific past date — ideal for incident retrospectives, compliance audits, trend analysis over time, or comparing current vulnerability posture against a past baseline. Use the sibling 'today' endpoint for current rankings. This endpoint is specifically for date-anchored archive lookups, not real-time or live data.

## Known failure modes

- Date not found in archive — brief not yet generated or date is in the future
- Invalid date format — must be YYYY-MM-DD
- Payment failure — x402 micropayment of $0.05 USDC not completed
- Unauthorized CVE route access — requires AIS CVE key for unlocked routes
- Date too far in the past — archive may not extend to requested date
- Rate limiting or API key exhaustion

## How this service works

Historical AIS daily brief by date (YYYY-MM-DD) — or unlock every CVE route with an AIS CVE key ($19/30d): https://aislabs.ai/gateway/

## Output

A structured daily CVE brief as it existed on the specified date, including AIS-ranked vulnerabilities with priority scores, CISA KEV flags, EPSS probability scores, patch availability status, and methodology notes explaining why each CVE was ranked where it was.
