# SSL Checker API
[](https://ssl-checker.api.klymax402.com/mcp)
[](https://x402.org)
[](LICENSE)
Check SSL/TLS certificate validity, expiry, issuer, chain details, and security grade for any domain. Pay-per-call via [x402](https://x402.org) (USDC on Base L2) -- no API key, no signup, no rate-limit wall.
Part of the [klymax402](https://klymax402.com) marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.
## Quickstart -- MCP
Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):
```json
{
"mcpServers": {
"ssl-checker": {
"url": "https://ssl-checker.api.klymax402.com/mcp"
}
}
}
```
## Quickstart -- HTTP (x402)
```bash
curl -X POST "https://ssl-checker.api.klymax402.com/api/check" \
-H "Content-Type: application/json" \
-d '{"domain":"..."}'
# -> 402 Payment Required, with an x402 payment challenge in the response body
```
Any x402-aware client ([`@x402/fetch`](https://www.npmjs.com/package/@x402/fetch), [`x402-agent-tools`](https://www.npmjs.com/package/x402-agent-tools), ATXP) handles the 402 -> sign -> retry cycle automatically.
## Tools
| Tool | Method | Path | Price | Description |
|---|---|---|---|---|
| `security_check_ssl` | POST | `/api/check` | $0.005 | Check SSL certificate for a domain |
### `security_check_ssl`
Use this when you need to check if a domain's SSL/TLS certificate is valid, when it expires, and who issued it. Returns structured certificate data in JSON.
**Parameters**
| Name | Type | Required | Description |
|---|---|---|---|
| `domain` | string | yes | Domain name to check SSL certificate (e.g. example.com) |
Example response:
```json
{"domain":"example.com","valid":true,"expiryDate":"2026-12-15","daysRemaining":245,"issuer":{"name":"DigiCert","organization":"DigiCert Inc"},"protocol":"TLSv1.3","securityGrade":"A+"}
```
**When to use**: deploying a website, FOR monitoring certificate expiration, auditing security posture, and validating HTTPS setup.
**Not for**: DNS lookup (use `network_lookup_dns`), HTTP headers analysis (use `network_analyze_headers`), port scanning (use `network_scan_ports`).
