# ChainVerdict TLS Security Probe

> ChainVerdict TLS Security Probe is a paid API for AI agents from chainverdict.xyz, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-14).

Probes a given hostname over TLS to assess its security posture and certificate configuration

## Facts

- Endpoint: GET https://chainverdict.xyz/v1/security/tls/%7Bdomain%7D?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown

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 chainverdict-tls-security-probe-a5f9813c
```

Example prompt: Can you check the TLS security configuration for api.example.com and tell me if it has any vulnerabilities or weak cipher suites?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call TLS security check on a specific hostname without setting up your own scanning infrastructure. Ideal for spot-checks, pre-deployment audits, or verifying third-party domains. At $0.01 USDC per call via x402, it suits low-volume, on-demand security probing workflows.

## Known failure modes

- Domain does not exist or is unreachable — returns error indicating failed connection
- Invalid hostname format — returns validation error
- TLS handshake failure — may return partial results or error
- Payment not provided — returns HTTP 402 with payment requirements
- Rate limiting or upstream network issues may cause timeouts

## How this service works

x402 v2 pay-per-call. Unpaid requests receive HTTP 402 with payment requirements.

## Output

Returns a security verdict and detailed TLS inspection results for the given hostname, including certificate information, supported protocol versions, cipher suites, and any identified vulnerabilities or misconfigurations.
