# CodePulse API – SSL Certificate Expiry Checker

> CodePulse API – SSL Certificate Expiry Checker is a paid API for AI agents from codepulse-api.hahavoid0.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Checks the SSL/TLS certificate validity and expiry date for a given domain, returning issuer, validity status, and expiration timestamp.

## Facts

- Endpoint: POST https://codepulse-api.hahavoid0.workers.dev/network/ssl-expiry
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/codepulse-api-ssl-certificate-expiry-checker-cc3605bc
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_HSIBYAnllcoAJvNN6unkH

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 codepulse-api-ssl-certificate-expiry-checker-cc3605bc -d '<json body>'
```

Example prompt: Can you check whether the SSL certificate for api.myapp.com is still valid and tell me when it expires?

## When to prefer this

Use this endpoint when you need a quick, low-cost, pay-per-call SSL certificate status check without setting up your own monitoring infrastructure. Ideal for agents that need to verify certificate validity on demand, audit third-party domains, or trigger alerts before expiry. Prefer this over full certificate scanning tools when you only need validity, issuer, and expiry date for a single domain at $0.01 per call.

## Known failure modes

- Domain does not exist or is unreachable — may return supported: false or an error
- Domain uses a self-signed or untrusted certificate — may still return data but with warnings
- Cached data may be slightly stale, indicated by data_as_of field
- Malformed domain input (e.g. including protocol prefix) may cause a validation error
- Very new domains with no certificate may return empty or unsupported results

## How this service works

Checks domain certificate logs on CertSpotter for SSL expiry dates and issuers.

## Output

Returns a JSON object with: `valid` (boolean indicating whether the cert is currently valid), `issuer` (the certificate authority name), `not_after` (ISO 8601 expiry timestamp), `warnings` (any notable issues), `supported` (whether the domain supports SSL), `confidence` (data reliability level), and `data_as_of` (freshness indicator for cached results).
