# SYNTHORA Chokepoint Risk

> SYNTHORA Chokepoint Risk 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).

Returns a supercorrelated risk verdict for major maritime chokepoints by fusing real vessel traffic, global news sentiment, and sea-state data into a single score with confidence level.

## 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-chokepoint-risk-807a4f18 -d '<json body>'
```

Example prompt: What's the current chokepoint risk score for the Strait of Hormuz — I want to know if the news narrative is actually backed by real traffic disruption or if the market is overreacting.

## When to prefer this

Choose this endpoint when you need a single fused risk verdict for a specific maritime chokepoint that combines vessel traffic reality, news narrative momentum, and sea-state navigability — especially when detecting divergences between market narrative and actual disruption. Prefer this over raw news sentiment APIs (which lack traffic grounding) or pure vessel-tracking APIs (which lack narrative context). Ideal for prediction market alpha, commodity risk desks, and supply chain early-warning use cases.

## Known failure modes

- Degraded source data (e.g. IMF PortWatch outage) reduces confidence score rather than failing outright
- Unrecognized or unsupported chokepoint name returns an error
- Malformed input string causes a 400-level response
- Payment failure via x402 results in 402 Payment Required before any computation
- Temporary GDELT data lag may produce stale narrative scores

## How this service works

SYNTHORA chokepoint-risk: SUPERCORRELATED risk verdict per maritime chokepoint (Hormuz, Suez, Panama, Bab el-Mandeb, Malacca, Gibraltar, Taiwan) — crosses REAL TRAFFIC (IMF PortWatch, canonical Polymarket resolution source) x NARRATIVE (GDELT global news spike+tone) x NAVIGABILITY (WaveWatch III sea state) into one score with confidence level. The alpha: narrative/traffic divergence (noise without disruption = market overreaction; silent disruption = early signal). Sources declared; degraded sources lower confidence. $0.05 USDC x402 Base.

## Output

A structured risk verdict for the requested maritime chokepoint including: a composite risk score, a confidence level (lowered when source data is degraded), a narrative-vs-traffic divergence signal indicating whether news sentiment is ahead of or behind actual vessel traffic, the current sea-state contribution from WaveWatch III, and declared source availability status.
