# 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, $0.01/call, status unknown (last checked 2026-10-21).

Sends an HTTP ping to a target URL and returns reachability status, HTTP status code, and latency measurement via x402 micropayment on Base.

## Facts

- Endpoint: POST https://138-68-190-61.nip.io/check-ping?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-21
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/hybrid-agent-api-ping-check-1144781d
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_Fau78lVfhC2ZMV8Cv_VAo

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-1144781d -d '<json body>'
```

Example prompt: Can you ping https://example.com and tell me if it's up, what HTTP status it returned, and how long it took to respond?

## When to prefer this

Use this endpoint when you need a quick, lightweight reachability check of any HTTP/HTTPS URL without setting up your own monitoring infrastructure. It is ideal for one-off verification tasks, pre-flight checks before automated workflows, or agent-driven uptime probes. Prefer this over general-purpose web scraping endpoints when you only need status/latency rather than page content.

## Known failure modes

- Target URL is unreachable or DNS fails — success: false with error_message explaining the network failure
- Invalid or malformed URL supplied — request rejected or connection error returned
- Target URL times out — success: false with a timeout error_message
- x402 payment fails or insufficient USDC balance — payment gateway error before the ping is executed
- Target returns a non-2xx status — captured in status_code field but success may still be false depending on implementation

## 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 indicating whether the ping succeeded (success boolean), the HTTP status code returned by the target, the round-trip latency in milliseconds, the timestamp of the check, the target URL echoed back, and an error message if the request failed.
