# Status State API – Solana Status Change History

> Status State API – Solana Status Change History 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 2026-10-10).

Returns up to 20 recent status/component/incident change events for Solana's services, ordered newest-first, paid per-call in USDC via x402 protocol.

## Facts

- Endpoint: GET https://status-state-api.replit.app/api/monitors/solana/changes?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-10
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/status-state-api-solana-status-change-history-d676f9dc
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_ieOoyt0KNMaJh9GANm07A

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-solana-status-change-history-d676f9dc
```

Example prompt: Show me the most recent status and incident changes for Solana — I want to see up to 20 events, newest first, so I can tell if there's been an outage or degradation recently.

## When to prefer this

Use this endpoint when you need the sequential history of Solana status events (what changed and when) rather than a point-in-time snapshot. It is ideal for incident investigation, post-mortems, trend detection, or alerting workflows that need to know what transitions occurred. The 402 preview (overallStatus + hasActiveIncident) lets you avoid paying if nothing interesting is happening. Prefer over snapshot endpoints when you need chronological movement data, not just current state.

## Known failure modes

- Payment not sent or insufficient USDC balance — 402 response with preview fields but no change array
- Invalid or unrecognized slug — 404 or empty result
- Stale data if Solana's status page is unreachable — staleness object will indicate age
- PayAI facilitator unavailable — payment cannot be verified, request blocked
- Network timeout from Replit-hosted service — intermittent 5xx errors

## How this service works

Up to 20 real status/component/incident movements, newest first - not the current snapshot. 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

A JSON array of up to 20 status/component/incident change events for Solana, ordered newest-first. Each event captures what changed (component name, status transition, incident open/close). Also includes an overallStatus field and a hasActiveIncident boolean (visible in the 402 response body before payment) plus staleness metadata indicating how fresh the data is.
