# SYNTHORA Marine Daily Brief

> SYNTHORA Marine Daily Brief is a paid API for AI agents from marine-daily.hergertsynthora.com, paid per call via x402, $0.5/call, status unknown (last checked 2026-10-28).

Delivers a daily structured intelligence brief on vessel traffic and sanctions signals across the world's major maritime chokepoints, based on proprietary AIS listener data.

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 synthora-marine-daily-brief-71b70572 -d '<json body>'
```

Example prompt: Give me today's maritime chokepoint brief — I want to see vessel traffic counts, any anomalies, and sanctions signals across Hormuz, Suez, Panama, Malacca, and Gibraltar.

## When to prefer this

Choose this endpoint when you need a daily, structured, ready-to-consume intelligence brief on maritime chokepoint activity and sanctions signals, backed by a proprietary AIS listener rather than relying on third-party data resellers. It is ideal for compliance workflows, shipping routing decisions, and geopolitical risk monitoring that require honest data coverage disclosures and cryptographic response integrity (ed25519 receipt). It is not suitable for real-time, sub-hourly vessel tracking or historical data retrieval.

## Known failure modes

- No AIS listener coverage for the day — brief returns 'sin cobertura del listener' rather than fabricated data
- Cache not yet pre-warmed if requested before 06:00 UTC — may return stale or unavailable status
- Payment not processed via x402 on Base — request rejected with 402 status
- Invalid op enum value — request rejected with schema validation error
- Network or service downtime — endpoint unavailable

## How this service works

SYNTHORA sanctions-marine-daily: the daily premium brief of chokepoint maritime movements + sanctions signal. Every day our OWN AIS listener aggregates real vessel traffic in Hormuz, Suez, Panama, Malacca and Gibraltar (bbox-filtered), crosses the AIS x sanctions signal (OFAC/UE, deterministic), and the Comandante writes an honest structured ES brief: {fecha, chokepoints[{zona,n_vessels,anomalias,senal_sanciones}], movimientos_destacados, riesgo_general}. No data = honest 'sin cobertura del listener' (never invented). Daily cache, pre-warmed 06:00 UTC. Premium pack, no free tier. 0.50 USDC per brief via x402 on Base.

## Output

A structured JSON object containing today's date, an array of chokepoint entries (zone name, vessel count, anomalies list, sanctions signal score), a UTC time window, highlighted movements of note, and an overall general risk assessment — plus a cryptographic receipt (ed25519) confirming the response. If no AIS listener data is available, the brief honestly reports 'sin cobertura del listener' rather than inventing data.
