# SYNTHORA Shipping Alpha — Physical vs Price Divergence

> SYNTHORA Shipping Alpha — Physical vs Price Divergence is a paid API for AI agents from api.hergertsynthora.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Crosses live physical shipping/logistics data (chokepoint transits, sea navigability) with current stock prices for major shipping stocks to surface unpriced deterioration signals for investors.

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-shipping-alpha-physical-vs-price-divergence-ee7d2e5d -d '<json body>'
```

Example prompt: Check if there's a physical-vs-price divergence signal for ZIM and Maersk right now — I want to know if deteriorating chokepoint transit or wave navigability data hasn't been priced into the stocks yet and what the confidence level is.

## When to prefer this

Use this endpoint when you need a quantitative, data-fused signal specifically combining live maritime physical reality (port chokepoint transits, sea navigability) with equity price movements for shipping/logistics stocks. It is distinct from pure financial data APIs because it ingests real-world physical shipping conditions; prefer it over generic financial alpha endpoints when the investment thesis involves maritime or logistics operational risk that equity markets may not yet have digested.

## Known failure modes

- IMF PortWatch or WaveWatch III data unavailable — partial result with reduced confidence score
- Stock price feed delay — divergence calculation may be stale
- Unrecognized ticker/stock name in input — returns error or empty result
- Chokepoint data not yet updated for recent events — confidence flag raised
- x402 payment failure — endpoint returns 402 and no data

## How this service works

SYNTHORA shipping-alpha: physical-vs-price divergence for shipping/logistics stocks (ZIM, Maersk AMKBY, Hapag-Lloyd, FedEx, UPS, Matson) — crosses LIVE physical reality (IMF PortWatch chokepoint transits + WaveWatch III navigability) with the official stock price move. Physical deterioration not yet priced = the investor window. 3 independent free sources crossed, confidence declared. $0.05 USDC x402 Base.

## Output

Returns a divergence analysis for one or more shipping/logistics stocks showing: current physical conditions (IMF PortWatch chokepoint transit volumes, WaveWatch III navigability scores), official stock price movement, the computed divergence gap indicating unpriced physical deterioration or improvement, an investor window assessment, and a declared confidence score derived from 3 independent free data sources.
