# npm Status Monitor API

> npm Status Monitor API 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 2026-10-18).

Returns the current normalized health status, component breakdown, and active incident details for npm's infrastructure

## Facts

- Endpoint: GET https://status-state-api.replit.app/api/monitors/npm?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-18
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/npm-status-monitor-api-71c3f575
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_mWTgx4m_cAvb1F4sVFKfN

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 npm-status-monitor-api-71c3f575
```

Example prompt: Can you check whether npm is currently up or experiencing any outages, and tell me if there are any active incidents affecting the registry?

## When to prefer this

Use this endpoint when you need a normalized, structured status snapshot for npm specifically — particularly when you want fault-first component ordering, active incident detail, and a staleness signal in a single call without managing API keys. Prefer this over scraping npm's status page directly when you need machine-readable JSON and pay-per-use economics via x402.

## Known failure modes

- Payment not provided or insufficient: 402 response with overallStatus and hasActiveIncident preview in body
- Invalid or unknown slug: endpoint may return 404 or empty result
- Stale data: sourceUpdatedAt may lag if upstream status page is unresponsive
- Network timeout: Replit-hosted service may have cold-start latency

## 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 npm slug and name, an overallStatus string (e.g. 'operational', 'degraded', 'outage'), an array of components sorted fault-first, an activeIncident object (or null), a closedIncidentSummary if the last incident is recent but closed, timestamps for lastCheckedAt and sourceUpdatedAt, staleness metadata, and checkIntervalMinutes indicating how often the monitor polls.
