# SYNTHORA Port-Watch

> SYNTHORA Port-Watch is a paid API for AI agents from api.hergertsynthora.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-14).

Returns daily port activity metrics for any of 2,065 global ports, including port calls, import/export capacity (dwt), 7-day moving average vs 30-day baseline deviation, and anomaly flags sourced from IMF PortWatch satellite AIS data.

## Facts

- Endpoint: POST https://api.hergertsynthora.com/v1/port-watch
- Price: $0.03/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/synthora-port-watch-72287e30
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_7bsC59B7zpFOPYjsy96vm

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-port-watch-72287e30 -d '<json body>'
```

Example prompt: Pull today's port activity for Shanghai — I want the port call count, import/export DWT capacity, the 7-day moving average vs 30-day baseline deviation, and whether there's an anomaly flag.

## When to prefer this

Choose this endpoint when you need a leading macro indicator for trade flows, tariff impact, or recession signals — port volume data leads official statistics by weeks. Ideal for macro traders, supply chain analysts, and geopolitical risk monitors who need near-real-time satellite AIS-based shipping data for any of 2,065 global ports without requiring an API key.

## Known failure modes

- Unknown or misspelled port name returns an error or empty result
- Port not among the 2,065 covered ports returns no data
- IMF PortWatch upstream data delay causes stale or missing daily values
- Payment of $0.01 USDC via x402 not completed results in 402 Payment Required
- Network timeout if upstream AIS data pipeline is slow

## How this service works

SYNTHORA port-watch: daily port activity for any of 2,065 ports (Shanghai, Singapore, Rotterdam, LA, Long Beach presets + any name) — port calls, estimated import/export capacity (dwt), 7d moving average vs 30d baseline deviation and anomaly flag. Port volume leads official macro data by weeks: the input for trade/tariff/recession markets. Source: IMF PortWatch (satellite AIS, free, no key). $0.01 USDC x402 Base.

## Output

Returns structured daily port metrics for the requested port: number of port calls, estimated import capacity (DWT), estimated export capacity (DWT), 7-day moving average for port activity, deviation from 30-day baseline, and a binary anomaly flag indicating statistically unusual activity. Data is sourced from IMF PortWatch satellite AIS feeds.
