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 upstream-ai-dev-api-status-deprecation-monitor-3c0bd23e -d '<json body>'
```

Example prompt: Is the Anthropic Claude API currently down, and has any model been deprecated recently — and if so, what replaced it?

## When to prefer this

Use this endpoint when you need real-time operational status or deprecation information specifically for AI and developer APIs (covering ~40 providers). Prefer it over generic uptime monitors (e.g. StatusPage, Better Uptime) when you need AI-domain-specific context like model deprecation notices and breaking-change feeds, not just ping/latency data. Ideal for agents that orchestrate multiple AI providers and need to fail-over or re-route when a provider is degraded.

## Known failure modes

- Unknown or unsupported provider name returns an error or empty result
- Provider not in the ~40 supported list returns a not-found response
- Exceeding 50 anonymous calls/day or 500 free-tier calls/day returns an x402 payment-required response
- Network timeout if the upstream status source is unreachable
- Stale data if the provider's status page hasn't been crawled recently

## 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 the current operational status of the specified AI/developer API provider, including whether the service is up or degraded, whether any models are deprecated, what models replace deprecated ones, and any recent breaking changes or incident alerts in the provider's feed.
