# Hybrid Agent API – Ping Check

> Hybrid Agent API – Ping Check is a paid API for AI agents from 138.68.190.61.nip.io, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-15).

Verifies that a target URL is reachable by performing an HTTP ping and returning status code, latency, and success/failure result.

## Facts

- Endpoint: POST https://138.68.190.61.nip.io/check-ping?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/hybrid-agent-api-ping-check-cba2853c
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_E7m32MnhrOCh2OQd-pwS2

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 hybrid-agent-api-ping-check-cba2853c -d '<json body>'
```

Example prompt: Can you ping https://api.myservice.com/health and tell me if it's up — and how many milliseconds it took to respond?

## When to prefer this

Choose this endpoint when you need a quick, real-time reachability check on a specific URL and want both the HTTP status code and latency in a single call. It is ideal for pre-flight checks before chaining further API calls, lightweight uptime probes, or webhook validation — especially when operating in an automated agent pipeline that uses x402 micro-payments on Base for per-call billing rather than subscription monitoring services.

## Known failure modes

- Target URL is unreachable or times out — success=false with an error_message and no status_code
- Invalid or malformed target_url input — request rejected with validation error
- Target server returns a non-2xx status — success may be false with the actual status_code captured
- Payment authorization fails via x402 — request blocked before execution
- DNS resolution failure for the target host — error_message reflects lookup failure

## How this service works

Autonomous agent utility network offering web scraping, document conversion, text summarization, and ping verification via x402 micro-payments on Base.

## Output

Returns a JSON object with a success boolean, the HTTP status code returned by the target URL, round-trip latency in milliseconds, a timestamp of the check, the echoed target URL, and an error message if the ping failed.
