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 an 'ok' boolean and a 'result' object containing: whether the URL was reachable, the actual HTTP status code returned, and whether it matched the expected status code (if one was provided).
Example use cases
Pre-call liveness check for agent pipeline
“Before my agent calls the payment API, can you ping https://api.payments.example.com/health with a GET and make sure it's reachable and returning 200?”
Schema validation before data ingestion
“Check that https://data.myservice.io/api/feed responds to a GET with a 200 and returns JSON that matches this schema: {"type":"object","properties":{"items":{"type":"array"}}}.”
Verify third-party webhook endpoint is live
“Can you do a HEAD request to https://hooks.partner.io/receive and tell me if it's reachable and what status code it returns?”
Technical details
Endpoint
POSThttps://api.gosyog.lol/api/service/yog/api_health_check?utm_source=zero.xyzWhen to prefer
Use this endpoint as a lightweight, free-tier liveness check when you need to confirm a URL is reachable and optionally validate its response status or JSON shape before invoking more expensive downstream operations. Prefer it over other Yog x402 endpoints (classify_text, json_repair, extract_fields) when you don't need LLM-based text processing — just a simple HTTP probe with optional schema assertion.
Side effects
- URL is unreachable or DNS fails — reachable: false with no status code
- Expected status does not match actual status — status_match: false
- Invalid URI format provided — validation error before request is made
- Timeout if remote server is slow to respond
- Expected JSON schema provided but response body is not JSON
