# VendSDK Bundle Infra — DNS + HTTP HEAD + TLS Probe

> VendSDK Bundle Infra — DNS + HTTP HEAD + TLS Probe is a paid API for AI agents from vendsdk.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-16).

Runs a bundled infrastructure check combining DNS A/AAAA resolution, HTTP HEAD probe, and TLS certificate peek for a given hostname or URL in a single paid call.

## Facts

- Endpoint: GET https://vendsdk.com/api/v/bundle-infra
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-16
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/vendsdk-bundle-infra-dns-http-head-tls-probe-9ee6eb19
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_ShZn_Ip3C_m0j2npfsWQy

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 vendsdk-bundle-infra-dns-http-head-tls-probe-9ee6eb19
```

Example prompt: Can you run a full infrastructure bundle check on api.example.com — I need to see the DNS A/AAAA records, whether it responds to an HTTP HEAD request, and the TLS certificate details all at once?

## When to prefer this

Choose this endpoint when you need DNS, HTTP reachability, and TLS certificate data for a host all in a single paid call ($0.01 USDC) rather than making three separate requests. It is ideal for agent infrastructure workflows, pre-deployment checks, vendor onboarding, and security audits where bundling saves round-trips and cost. Prefer sibling endpoints when you only need one of the three signals (e.g. the dedicated TLS-only or HTTP status/latency endpoint).

## Known failure modes

- Invalid or unresolvable hostname returns DNS failure in dns object with ok: false
- Host unreachable for HTTP HEAD returns error in http_head object
- TLS certificate missing or expired reflected in tls object fields
- Malformed URL/host parameter causes 400-level error
- Private or RFC-1918 addresses may be blocked for SSRF safety
- Timeout if remote host is very slow to respond

## How this service works

Single payment bundle: DNS A/AAAA, HTTP HEAD probe, and TLS certificate peek for agent infra workflows

## Output

Returns a JSON object with an 'ok' boolean, 'host' and 'service' strings, a 'dns' object with A/AAAA records, an 'http_head' object with status code and response headers, and a 'tls' object with certificate subject, issuer, expiry, and authorization status.
