01 x402 security intelligence

Cut the noise. Ship the fix.

Current vulnerability context, ranked for agents. Synthr turns OSV advisories, EPSS probability, and CISA KEV status into source-linked JSON your workflow can act on.

02 Intelligence menu

One endpoint.
One sharp answer.

Choose the exact security context your agent needs. Every call returns structured data designed for tools, CI, and autonomous workflows.

POST /v1/cyber/stack-brief

Prioritize a supplied dependency stack with OSV, EPSS, KEV, and agent-surface context.

curl -X POST 'https://synthr.online/v1/cyber/stack-brief' \
  -H 'Content-Type: application/json' \
  -d '{
    "stack": {
      "dependencies": [
        { "name": "hono", "version": "4.7.0", "ecosystem": "npm" }
      ]

03 The protocol

No signup maze.
Just request → pay → act.

  1. 01 / ASK

    Send context

    Your agent sends a dependency stack, CVE, or security question as structured JSON.

  2. 02 / PAY

    Sign once

    The endpoint returns an x402 challenge. Your client signs a tiny USDC payment—no API account.

  3. 03 / ACT

    Get the signal

    Receive source-linked findings with exploitability context and prioritized action cues.

04 Signal, not theater

Vulnerability data is cheap.
Knowing what matters isn’t.

Synthr composes public security signals into the decision layer an autonomous builder actually needs.

  • 01
    Exploit probability

    EPSS context helps separate theoretical exposure from likely exploitation.

  • 02
    Known exploitation

    CISA KEV flags raise urgency when a vulnerability is active in the wild.

  • 03
    Agent relevance

    Heuristic surface tags highlight auth, tool, and harness-adjacent risk.

  • 04
    Source-linked output

    Machine-readable results point back to the underlying advisories.
