# Status State API – Base Monitor

> Status State API – Base 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 2026-10-12).

Returns the current normalized operational status, fault-first component breakdown, and active or recent incident data for the Base blockchain network

## Facts

- Endpoint: GET https://status-state-api.replit.app/api/monitors/base?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-12
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/status-state-api-base-monitor-97a5d119
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_8PSilVagnD2ry4oYCo-xQ

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-base-monitor-97a5d119
```

Example prompt: Check if Base blockchain is currently up and whether there are any active incidents or degraded components right now.

## When to prefer this

Use this endpoint when you need a normalized, machine-readable operational status for the Base blockchain network specifically, especially when you want to avoid API key registration overhead. The x402 micropayment model ($0.01 USDC) makes it practical for agent-driven polling without subscription commitments. Prefer this over scraping Base's status page directly when you need structured JSON with fault-first component ordering and incident history in a single call. The 402 pre-flight that reveals overallStatus and hasActiveIncident is particularly useful for conditional logic — pay only when you need the full detail.

## Known failure modes

- Payment not accepted or insufficient USDC balance — HTTP 402 returned; overallStatus and hasActiveIncident still visible in 402 body
- Invalid or unrecognized slug (e.g. slug does not exist in monitor catalog) — likely 404 or error response
- Upstream status page unavailable causing stale data — staleness object will indicate age
- Network timeout from Replit-hosted service — transient 5xx response
- Rate limiting or infrastructure issues on the Replit host — 503 or similar

## 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: normalized overallStatus string (e.g. 'operational', 'degraded', 'outage'), an array of components sorted fault-first with their individual statuses, an activeIncident object if one is ongoing (or closedIncidentSummary if the last incident recently closed), timestamps for lastCheckedAt and sourceUpdatedAt, a staleness object, checkIntervalMinutes, and a hasActiveIncident boolean. The overallStatus and hasActiveIncident fields are also surfaced in the 402 payment-required response so callers can triage before paying.
