# broker-tls-scanner

> broker-tls-scanner is a paid API for AI agents from x402broker.com, paid per call via x402 or MPP, $0.01/call, status unknown (last checked 2026-10-20).

Inspects a domain's live DNS resolution (IPv4/IPv6), TLS certificate details (issuer, expiry), and HTTP security headers to produce a security grade.

## Facts

- Endpoint: GET https://x402broker.com/v1/tls-scanner?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402, MPP
- Status: unknown
- Last checked: 2026-10-20

- Canonical page: https://www.zero.xyz/c/broker-tls-scanner-976d74f1
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_a-wnY5VZihhHg1tlWVFih

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability broker-tls-scanner-976d74f1
```

Example prompt: Can you scan stripe.com and tell me its TLS certificate issuer, expiry date, whether it resolves on IPv4 and IPv6, and its HTTP security headers grade?

## When to prefer this

Choose this endpoint when you need a lightweight, single-call OSINT snapshot of a domain's TLS certificate, DNS resolution, and HTTP security posture without deploying full-scale vulnerability scanners. Ideal for pre-launch checks, vendor monitoring, or quick domain reconnaissance at $0.01 per call.

## Known failure modes

- Domain does not exist or fails DNS resolution — returns DNS lookup failure
- Domain is reachable but has no TLS/HTTPS — certificate fields will be empty or error
- TLS certificate is expired or self-signed — returned as data, not an API error
- Network timeout reaching the target domain — returns timeout error
- Invalid domain input format — returns validation error

## How this service works

Inspects live IPv4/IPv6 DNS resolution, TLS certificate issuer/expiry, and HTTP security grade. (Live x402 v2, IETF MPP & MCP endpoint at https://x402broker.com/v1/tls-scanner)

## Output

Returns live IPv4 and IPv6 DNS resolution results, TLS certificate details (issuer, subject, expiry date, validity status), and an HTTP security headers assessment including presence of headers like HSTS, CSP, X-Frame-Options, along with an overall HTTP security grade.
