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 straits-live-premium-stream-session-a30db2ab -d '<json body>'
```

Example prompt: Start a live Straits.live premium stream session for real-time Strait of Hormuz shipping ticks and Hormuz Index moves — go ahead and authorize the $0.05 USDC payment to get the signed token.

## When to prefer this

Choose this endpoint when you need a continuous, push-based real-time feed of Strait of Hormuz data (vessel ticks, index moves, events) without polling overhead. It is ideal for latency-sensitive trading systems, automated risk monitors, or any agent that must react to Hormuz crisis developments as they happen rather than on a scheduled pull basis. Prefer over the snapshot REST endpoints when sustained streaming and instant event delivery are required.

## Known failure modes

- Payment failure or insufficient USDC balance returns a 402 Payment Required error
- Expired or invalid signed token results in 401 Unauthorized on the SSE endpoint
- Token used after its short TTL has elapsed returns 403 Forbidden
- Malformed POST body (missing required type or method fields) returns 400 Bad Request
- Network interruption drops the SSE connection, requiring a new session purchase

## How this service works

Buy a real-time stream session: one payment returns a short-lived signed token that authenticates a Server-Sent Events connection at /api/premium/stream, pushing Strait of Hormuz ticks, Hormuz Index moves, and events without polling.

## Output

Returns a short-lived signed session token that the caller uses to authenticate a persistent Server-Sent Events connection at /api/premium/stream, which then pushes real-time Strait of Hormuz vessel ticks, Hormuz Index price moves, and geopolitical/shipping events without any further polling.
