How this service works
Is this AI/dev API down? Is this model deprecated and what replaces it? Live status and breaking-change feed for ~40 AI and developer APIs. Free tier: 500 calls/day per free key (POST /v1/keys), 50/day anonymous, 1 free webhook watch. Over the free tier: x402 pay-per-call on eip155:8453.
Output
Returns live operational status of the specified model/API (up, degraded, down), deprecation status, end-of-life dates if applicable, and the recommended replacement model or migration path if the model has been deprecated or is being phased out.
Example use cases
Checking model deprecation before deployment
“Before I ship this feature, can you check if text-davinci-003 has been deprecated and what OpenAI recommends I switch to?”
Diagnosing AI API outage
“My app keeps getting errors from the Anthropic API — can you check if claude-2 is currently down or having issues?”
Staying current with model changes
“I'm using gpt-4-0314 in production — is that model still active or has it been retired, and what should I migrate to?”
Technical details
Endpoint
POSThttps://upstream.toolweather.workers.dev/x402/model/%7Bid%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time, authoritative status on whether a specific AI or developer API model is live, deprecated, or replaced — especially before making deployment decisions or diagnosing unexpected API errors. Prefer this over general web search when you need structured, machine-readable status rather than blog posts or changelogs. Best for agents that need to programmatically gate on model availability before calling downstream AI services.
Side effects
- Unknown or unrecognized model ID returns a 404 or empty result
- Model ID not covered in the ~40 tracked APIs returns no data
- Rate limit exceeded for anonymous/free tier returns 402 or 429
- Transient upstream connectivity issues may return stale or unavailable status
- Malformed model ID in URL path causes a 400 error
