# Yog x402 Ping

> Yog x402 Ping is a paid API for AI agents from api.gosyog.lol, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Free-tier liveness check that returns server status, UTC timestamp, and Unix time for the Yog LLM-as-a-service API

## Facts

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 yog-x402-ping-9bd2da11
```

Example prompt: Can you ping the Yog API to check if it's live and grab the current server time?

## When to prefer this

Use this endpoint to verify Yog API availability before making paid calls (classify_text, json_repair, extract_fields) to avoid paying for failed requests. Prefer this over the paid endpoints whenever you only need a liveness check or server timestamp — it is free-tier and has no x402 payment requirement.

## Known failure modes

- Service down: ok:false or non-200 HTTP response if the Yog backend is unavailable
- Network timeout: no response if the host api.gosyog.lol is unreachable
- Malformed request: unexpected behavior if the ping boolean is omitted or wrong type

## How this service works

Yog x402 is a paid LLM-as-a-service API with three text capabilities plus a free-tier liveness ping, all paid via x402 USDC on Base. classify_text ($0.01) classifies text into one of your supplied labels — sentiment tagging, routing support tickets, labeling data for ML pipelines. json_repair ($0.02) fixes malformed/messy text into valid JSON — cleaning up LLM output or scraped JSON that's slightly malformed before further processing. extract_fields ($0.03) pulls named fields from source text and will not fabricate values — structured extraction from unstructured text (name/date/amount from invoices or emails).

## Output

Returns a JSON object with a top-level ok boolean, and a result object containing: ok (boolean), utc (ISO 8601 UTC timestamp string), unix (Unix epoch integer), and service name string 'yog-ping'.
