## 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 agent-services-x402-tls-ssl-certificate-checker-e0f4d69c
```

Example prompt: Can you check the SSL certificate for api.mycompany.com — is it valid, who issued it, and how many days are left before it expires?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call TLS certificate check without maintaining your own SSL monitoring infrastructure. It's ideal for AI agents that need on-demand, real-time certificate status rather than continuous polling services. Best suited for spot-checks, pre-deployment validation, or vendor security assessments where cost-per-call (0.0005 USDC) is acceptable.

## Known failure modes

- Host not found or unreachable — returns error or empty result
- Domain has no TLS certificate — may return invalid/null fields
- Network timeout fetching certificate — returns error response
- Malformed host input — returns validation error
- Expired certificate — returns valid:false with negative or zero days_left

## How this service works

Paid per-call web tools for AI agents: DNS, TLS, robots.txt, hashing, JavaScript rendering and screenshots. Payment over x402 (USDC on Base).

## Output

Returns a JSON object with the queried host, a boolean indicating whether the certificate is valid, the certificate issuer name (e.g. 'Let's Encrypt'), and the number of days remaining until expiration.
