How this service works
Compute exact CVSS v3.1 Base Score (0.0-10.0) and severity rating from a CVSS v3.1 vector string.
Output
Returns the computed CVSS v3.1 Base Score as a decimal between 0.0 and 10.0, along with the corresponding severity rating (None, Low, Medium, High, or Critical) derived from the vector string.
Example use cases
Triage incoming CVE severity
“I just got a security advisory with the vector CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:L/A:N — can you tell me the base score and whether it's critical, high, medium, or low?”
Automate vulnerability scoring pipeline
“For each of these CVSS v3.1 vectors from our scan report, compute the exact base score so I can sort them by severity and prioritize patching.”
Verify manual CVSS calculation
“I calculated this vulnerability as a 9.8 Critical using CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H — can you double-check my score is correct?”

Endpoint
GEThttps://bot-bazaar.fly.dev/v1/x402/cvss-v31-score-calc?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a precise, standards-compliant CVSS v3.1 Base Score and severity label from a vector string — especially in automated vulnerability triage, security reporting pipelines, or when verifying a manually computed score. Prefer this over general-purpose LLM calculations, which may approximate rather than compute exactly per the CVSS v3.1 specification.
Side effects
- Invalid or malformed CVSS v3.1 vector string returns an error
- Missing required vector query parameter causes a 400-level response
- Vector strings from other CVSS versions (v2.0, v3.0, v4.0) may not be accepted or may return incorrect results
- Network timeout or service unavailability on fly.dev infrastructure
