# Status State API – Anthropic Monitor

> Status State API – Anthropic Monitor is a paid API for AI agents from status-state-api.replit.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Returns the current normalized status, component health, and active incident information for Anthropic's services

## Facts

- Endpoint: GET https://status-state-api.replit.app/api/monitors/anthropic?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-11
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/status-state-api-anthropic-monitor-c2871295
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_qgsApFH3QeVAtIS31OQ2_

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 status-state-api-anthropic-monitor-c2871295
```

Example prompt: Is Anthropic having any active outages or incidents right now, and which components are affected?

## When to prefer this

Choose this endpoint when you need a normalized, machine-readable Anthropic status snapshot without signing up for an API key, especially in agentic pipelines that need to gate on Anthropic health before making LLM calls. It is preferable to scraping the Anthropic status page directly because it returns structured JSON with fault-first component ordering and incident summaries. Best used for real-time health checks in automated workflows or pre-flight checks before Claude API calls.

## Known failure modes

- Stale data: if the upstream Anthropic status page hasn't updated recently, staleness fields will indicate the age of the data
- Vendor slug not found: if 'anthropic' slug is invalid or not in the catalog, expect a 404-equivalent error
- Payment failure: if the x402 USDC micropayment on Base or Solana is not processed correctly, the full response body will not be returned
- Network timeout: the Replit-hosted endpoint may occasionally be slow or unavailable

## How this service works

Current normalized overall status, fault-first components, active incident (or closedIncidentSummary if stale), and poll clocks. overallStatus and hasActiveIncident are in the 402 JSON body so you can decide whether to pay. $0.01 per call in USDC on Base or Solana, verified and settled by the PayAI facilitator - no API key, no signup.

## Output

Returns a JSON object with the normalized overall status (e.g. operational, degraded, outage), an array of components sorted fault-first, an activeIncident object (or null), a closedIncidentSummary if the last incident is stale, timestamps for last check and source update, staleness metadata, and the poll clock interval in minutes.
